I got the following message below and have no idea what to do?

TypeLoadException: Method 'Create' in type 'Microsoft.EntityFrameworkCore.SqlServer.Query.Internal.SqlServerSqlTranslatingExpressionVisitorFactory' from assembly 'Microsoft.EntityFrameworkCore.SqlServer, Version=3.1.3.0, Culture=neutral, PublicKeyToken=adb9793829ddae60' does not have an implementation.

Below is my code for ApplicationDbContext:

Hello,

     So I had this working in Asp.net Core 2.2 with Twitter-Bootstrap 3.3.7.  I then upgraded to Asp.net Core 3.1 and Twitter-Bootstrap 4.4.  Now I am unable to get some of my javascript functions to work.  Setting breakpoints in the javascript in Chrome and Edge, they do not get hit at all.  Though I ran the output from the web through JS Fiddle and it works perfectly fine there.  So I am at a loss for what I did to break this.

What I have is a gating function within javascript that will uncheck any check boxes that are in sequence after a check box if it is unchecked, if it is checked it will enable the next available check box, leaving the others disabled.  When I run it in IIS Express this no longer happens.

Here is the Javascript I have for one page:

//Loops through the checkboxes and disables the next ones if the previous is not checked
function changeFields(fields) {
    fields.change(function () {
        Array.prototype.reduce.call(fields, function (prev, curr) {
            curr.disabled = !prev.checked || prev.disabled;


            //If you want to uncheck remaining use this instead of above line:
            curr.checked = prev.checked ? curr.checked : false;
            curr.disabled = !prev.checked;

            return curr;
        });
    });
}

//Call the for the CharacterCraft
changeFields($(".cALScb"));
changeFields($(".cALMcb"));
changeFields($(".cBLScb"));
changeFields($(".cBLMcb"));
changeFields($(".cCLScb"));
changeFields($(".cCLMcb"));

Here is the what I have in view calling this:

Everything displays correctly on the page, but after an unchecked check box everything is still enabled.  This can been seen in the output from Edge:

Ideally from the output the very last check box should be disabled, but it is not.  Though if I go to JS Fiddle, this works as such: https://jsfiddle.net/MikeRM2/bzfcme06/

So this leads to wondering what went wrong, as it works in JS Fiddle but not on the actual site.  I am not getting any errors in the console or debug.  Any thoughts on why this is not working anymore would be appreciated.

I tried to use below code in asp.net but there is error in html tags like and and say it could not find begin tag. but begin tag is in first if. the errors are in between line 44 to 52.

                j =1;else

Hey everyone. I'm new to asp net core and i need some help. I scaffolded the Identity into my  web form razor project. The database name is ProiectLicenta where i can see all the Indentity tables. Basically what i am trying to do is if anyone registers i want their usernames and emails from the AspNetUsers table listed in another page called userlist. That table on the userlist has to update everytime a new person registers. Is it posible?

Dear all,

I am getting the following error in asp.net core project. Can somebody let me know how to overcome this error.

hi,
with this code i upload my file in .net core ,
i want when internet is disconnected , the upload operation is paused and
when internet is connected it continue the upload
how can i do this in javascript & .net core?

 document.getElementById('upload-video').addEventListener('change', function (event) {

       var file = event.target.files[0];
       console.log($("#upload-video").val());
       var fileReader = new FileReader();
       var extension = file.type.split("/");

           fileReader.onload = function () {
               var blob = new Blob([fileReader.result], { type: file.type });
               var url = URL.createObjectURL(blob);
               var video = document.createElement('video');
               var timeupdate = function () {
                   if (snapImage()) {
                       video.removeEventListener('timeupdate', timeupdate);
                       video.pause();
                   }
               };
               video.addEventListener('loadeddata', function () {
                   GetDuration(video.duration);


               });

               var snapImage = function () {
                   var canvas = document.createElement('canvas');

                   canvas.width = video.videoWidth;
                   canvas.height = video.videoHeight;

                   canvas.getContext('2d').drawImage(video, 0, 0, canvas.width, canvas.height);
                   var image = canvas.toDataURL();
                   var success = image.length > 10000;
                   var image = canvas.toDataURL();
                   if (success) {
                       var img = document.getElementById('video-image');
                       img.src = image;

                       if (document.contains(document.getElementById("upload-preview-loader"))) {
                           document.getElementById('upload-preview-loader').remove();
                       }

                       img.hidden = false;
                       document.getElementById('div-image').appendChild(img);
                       URL.revokeObjectURL(url);

                   }

                   return success;
               };
               video.addEventListener('timeupdate', timeupdate);
               video.preload = 'metadata';
               video.src = url;
               video.muted = true;
               video.playsInline = true;
               video.currentTime = 30;
               video.play();


           
               SendVideo();



           fileReader.readAsArrayBuffer(file);
       }
   });

function SendVideo() {

    var image = $("#upload-video").get(0).files;
    var aVF = new FormData();
    aVF.append("file", image[0])$.ajax({
        method: 'POST',
        url: '/Video/Upload',
        data: aVF,
        processData: false,
        contentType: false,
        xhr: function () {$("#progress-bar-video").addClass("bg-info");$("#progress-bar-video").removeClass("bg-success");
            var xhr = new window.XMLHttpRequest();
            xhr.upload.addEventListener("progress", function (evt) {
                if (evt.lengthComputable) {
                    //console.log(evt.loaded + " / " + evt.total);
                    var progress = Math.round((evt.loaded / evt.total) * 100);$(".progress-bar").css("width", progress + "%").attr("aria-valuenow", progress);$(".progress-bar").html('(' + progress + "%) در حال بارگذاری");
                }
            }, false);
            return xhr;
        },
        success: function (data) {

         //do something
            }

            //




        },
        complete: function (data) {
            //do something
        },
        error: function (result) {
        }
    });
}

My code reads a website field from a database.  The field's values are things likewww.google.com, www.bing.com etc without the preceding http:// (orhttps://).

The MVC model returns and displays this field correctly, but I can't get it to prepend http:// and then make the entire thing clickable.

This is the code I have:

@foreach (var item in Model) {
<tr>
   <td>
   @if (item.PrimarySiteName != null)
   {
      @Html.Raw(@("http://" + @item.PrimarySite))
   }
   </td>

</tr>

}

Without the @Html.Raw, the field actually displays correctly, but this code doesn't even run.  Maybe I need to use <a href=""> to wrap the prepended string.  Depending upon how I mess with the code, sometimes the double slash is interpreted as a comment ( when I use @{ } for example ).  How can I get this link to display and be clickable?

Hi

One of the main reasons i don't use visual studio code more, is because of all the command line stuff,like for creating new projects, solutions etc.

Does anyone have any good resources for command line stuff i can bookmark or print for referencing.

I want to start a new asp.net core MVC web project, but i am but sure if i can follow the database first approach? by creating the database inside my sql server >> then map the database inside my application using entity framework (as we used to do in asp.net mvc-5)? Thanks

Any idea why am I getting this error?   Error Message --> "IServiceCollection does not contain a definition for AddDefaultIdentity"

public class Program
{
  public async static void Main(string[] args)
  {
    await Host.CreateDefaultBuilder(args)
    .ConfigureWebHostDefaults(webBuilder => {
      webBuilder.UseContentRoot(Directory.GetCurrentDirectory());
      webBuilder.UseKestrel();
      webBuilder.UseAzureAppServices();
      webBuilder.UseStartup<Startup>();
    })
    .Build()
    .RunAsync();
  }
}

Hi

I have some entities like Patients with some relations to another entities. My problem is that, in Details view, the navigation properties (which points to other tables) does not display anything! apparently it returns null.

after a lot of search, some people says i should change some configation options in my dbContext (see this link), but i could not find Configuration property!

some people says Lazy loading is not supported by ef core, i should include it manually in my linq query (see this link), but also i could not find Include in my dbContext!!

Here is my Patients class :

public partial class Patients
{
        [Key]
        public Guid PatientRowID { get; set; }
        [Required]
        [StringLength(50)]
        public string PatientCaseID { get; set; }
        [StringLength(50)]
        public string PatientFname { get; set; }
        [StringLength(50)]
        public string PatientLname { get; set; }
	public int? SexID { get; set; }
	[ForeignKey(nameof(SexID))]
        [InverseProperty("Patients")]
        public virtual Sex Sex { get; set; }
}

And here is my another table (Sex) :

public partial class Sex
{
        public Sex()
        {
            Patients = new HashSet<Patients>();
            Persons = new HashSet<Persons>();
        }

        [Key]
        public int SexID { get; set; }
        [StringLength(50)]
        public string SexName { get; set; }

        [InverseProperty("Sex")]
        public virtual ICollection<Patients> Patients { get; set; }
        [InverseProperty("Sex")]
        public virtual ICollection<Persons> Persons { get; set; }
}

And here is my action method :

public IActionResult Details(string id)
        {
            if (string.IsNullOrEmpty(id))
                return BadRequest();

            Guid gid = Guid.Parse(id);
            var patient = _dbContext.Patients.Where(p => p.PatientRowID == gid).FirstOrDefault();
            if (patient == null)
                return NotFound();

            return View(patient);
        }

And here is my Details view code :

<div><dl class="row"><dt class = "col-sm-2">
            @Html.DisplayNameFor(model => model.PatientCaseID)</dt><dd class = "col-sm-10">
            @Html.DisplayFor(model => model.PatientCaseID)</dd><dt class = "col-sm-2">
            @Html.DisplayNameFor(model => model.PatientFname)</dt><dd class = "col-sm-10">
            @Html.DisplayFor(model => model.PatientFname)</dd><dt class = "col-sm-2">
            @Html.DisplayNameFor(model => model.PatientLname)</dt><dd class = "col-sm-10">
            @Html.DisplayFor(model => model.PatientLname)</dd><dt class = "col-sm-2">
            @Html.DisplayNameFor(model => model.SexID)</dt><dd class = "col-sm-10">
            @Html.DisplayFor(model => model.Sex.SexName) // display nothing!</dd></dl></div>

Can anybody help me where is my problem & how to solve it?

Thanks in advance

Good morning, I have a question about something I am trying to develop, the project is in ASP CORE 3.1 MVC. I have 2 identities one to one and the other (which is the one with problems) from one to many. What happens is that I am adding a company (Company Model) and those responsible for this company (Company Responsable Model) which are the following:

publicpartialclassEmpresa{publicintEmpresaId{get;set;}publicstringNombreEmpresa{get;set;}publicstringNumeroDistribuidor{get;set;}publicstringUbicacion{get;set;}publicstringRazonSocial{get;set;}publicstringDomicilio{get;set;}publicstringTelefono{get;set;}publicstringCorreo{get;set;}publicintCantidadEmpleados{get;set;}publicstringFechaAlta{get;set;}publicstringHoraAlta{get;set;}publicstringFechaModificacion{get;set;}publicstringHoraModificacion{get;set;}publicstringUsuarioAlta{get;set;}publicstringUsuarioModificacion{get;set;}publicbool?Estado{get;set;}publicvirtualNaturalezaEmpresaNaturalezaEmpresa{get;set;}publicICollection<ResponsableEmpresa>ResponsableEmpresas{get;set;}}}

Model ResponsableEmpresa:

publicintResponsableEmpresaId{get;set;}publicstringPuesto{get;set;}publicstringNombre{get;set;}publicstringApellidoMaterno{get;set;}publicstringApellidoPaterno{get;set;}publicstringCorreo{get;set;}publicstringTelefono{get;set;}[ForeignKey("Empresa")]publicintEmpresaId{get;set;}publicvirtualEmpresaEmpresa{get;set;}

Now, what I try is that in the view I can add the data of the company and separate those responsible, which would be the following view:

@modelEmpresa<h1 class="text-center">Datos generales de la empresa o grupo</h1><form asp-action="Guardar" asp-controller="Empresa" method="post"><div class="form-group col"><label>Nombre de la empresa:</label><input type="text" asp-for="NombreEmpresa"class="form-control"/><span asp-validation-for="NombreEmpresa"class="text-danger"></span></div><div class="form-group col"><label>Número de distribuidor:</label><input type="text" asp-for="NumeroDistribuidor"class="form-control"/><span asp-validation-for="NumeroDistribuidor"class="text-danger"></span></div><div class="form-group col"><label>Ubicación:</label><input type="text" asp-for="Ubicacion"class="form-control"/><span asp-validation-for="Ubicacion"class="text-danger"></span></div><div class="form-group col"><label>Razón Social:</label><input type="text" asp-for="RazonSocial"class="form-control"/><span asp-validation-for="RazonSocial"class="text-danger"></span></div><div class="form-group col"><label>Domicilio:</label><input type="text" asp-for="Domicilio"class="form-control"/><span asp-validation-for="Domicilio"class="text-danger"></span></div><div class="form-group col"><label>Telefono:</label><input type="tel" asp-for="Telefono"class="form-control"/><span asp-validation-for="Telefono"class="text-danger"></span></div><div class="form-group col"><label>Correo:</label><input type="email" asp-for="Correo"class="form-control"/><span asp-validation-for="Correo"class="text-danger"></span></div><div class="form-group col"><label>Cantidad de empleados:</label><input type="number" asp-for="CantidadEmpleados"class="form-control"/><span asp-validation-for="CantidadEmpleados"class="text-danger"></span></div><div class="form-group col"><label>Cantidad de empleados:</label><input asp-for="ResponsableEmpresas.Add(@responsableEmpresa)"class="form-control"/></div>@*<h1 class="text-center">ResponsableEmpresa</h1><p><br /><br /></p><table id="myTable"class="table table-bordered text-center"><thead><tr><td scop="col">Puesto</td><td scop="col">Nombre</td><td scop="col">ApellidoMaterno</td><td scop="col">ApellidoPaterno</td><td scop="col">Correo</td><td scop="col">Telefono</td></tr></thead><tbody><tr></tr></tbody></table><br><script>function myFunction(){var table = document.getElementById("myTable");

                document.getElementById("myTable").deleteRow(2);}function showTableData(){//gets tablevar oTable = document.getElementById('myTable');//gets rows of tablevar rowLength = oTable.rows.length;//loops through rowsfor(i =0; i < rowLength; i++){//gets cells of current rowvar oCells = oTable.rows.item(i).cells;//gets amount of cells of current rowvar cellLength = oCells.length;//loops through each cell in current rowfor(var j =0; j < cellLength; j++){// get your cell info herevar cellVal = oCells.item(j).innerHTML;if(cellVal.toString()!="Puesto"&& cellVal.toString()!="Nombre"&& cellVal.toString()!="Nombre"&& cellVal.toString()!="Apellido Materno"&& cellVal.toString()!="Apellido Paterno"&& cellVal.toString()!="Correo"&& cellVal.toString()!="Telefono"){

The idea is that a number of managers can be added, but I cannot find a way to add it that when returning to the controller brings the information of Company Responsible .

Basically the idea is to pass an array from the view to the controller, but I have the problem handling the ICollection

Thanks a lot!

I'm not sure where to sort the title at, would that be at the view level or in the repository?

i tried setting it in the repository but that doesn't seem to work

 public IEnumerable<DocumentEntity> FindPoliciesDocuments()
        {
            return DbContext
                .Set<DocEntity>()
                .Include(d => d.EgendaFile)
                .Where(d => d.EgendaDocumentTypeEntity.Id == (int)EgendaDocumentType.Policies)
                .Where(d => d.IsDeleted == false || d.IsDeleted == null).AsEnumerable()
                .OrderByDescending(d => d.Title);
        }

View which sorts the date but not the title which is what I want it to sort by.

Model ResponsableEmpresa:

publicintResponsableEmpresaId{get;set;}publicstringPuesto{get;set;}publicstringNombre{get;set;}publicstringApellidoMaterno{get;set;}publicstringApellidoPaterno{get;set;}publicstringCorreo{get;set;}publicstringTelefono{get;set;}[ForeignKey("Empresa")]publicintEmpresaId{get;set;}publicvirtualEmpresaEmpresa{get;set;}

Now, what I try is that in the view I can add the data of the company and separate those responsible, which would be the following view:

@modelEmpresa<h1 class="text-center">Datos generales de la empresa o grupo</h1><form asp-action="Guardar" asp-controller="Empresa" method="post"><div class="form-group col"><label>Nombre de la empresa:</label><input type="text" asp-for="NombreEmpresa"class="form-control"/><span asp-validation-for="NombreEmpresa"class="text-danger"></span></div><div class="form-group col"><label>Número de distribuidor:</label><input type="text" asp-for="NumeroDistribuidor"class="form-control"/><span asp-validation-for="NumeroDistribuidor"class="text-danger"></span></div><div class="form-group col"><label>Ubicación:</label><input type="text" asp-for="Ubicacion"class="form-control"/><span asp-validation-for="Ubicacion"class="text-danger"></span></div><div class="form-group col"><label>Razón Social:</label><input type="text" asp-for="RazonSocial"class="form-control"/><span asp-validation-for="RazonSocial"class="text-danger"></span></div><div class="form-group col"><label>Domicilio:</label><input type="text" asp-for="Domicilio"class="form-control"/><span asp-validation-for="Domicilio"class="text-danger"></span></div><div class="form-group col"><label>Telefono:</label><input type="tel" asp-for="Telefono"class="form-control"/><span asp-validation-for="Telefono"class="text-danger"></span></div><div class="form-group col"><label>Correo:</label><input type="email" asp-for="Correo"class="form-control"/><span asp-validation-for="Correo"class="text-danger"></span></div><div class="form-group col"><label>Cantidad de empleados:</label><input type="number" asp-for="CantidadEmpleados"class="form-control"/><span asp-validation-for="CantidadEmpleados"class="text-danger"></span></div><div class="form-group col"><label>Cantidad de empleados:</label><input asp-for="ResponsableEmpresas.Add(@responsableEmpresa)"class="form-control"/></div>@*<h1 class="text-center">ResponsableEmpresa</h1><p><br /><br /></p><table id="myTable"class="table table-bordered text-center"><thead><tr><td scop="col">Puesto</td><td scop="col">Nombre</td><td scop="col">ApellidoMaterno</td><td scop="col">ApellidoPaterno</td><td scop="col">Correo</td><td scop="col">Telefono</td></tr></thead><tbody><tr></tr></tbody></table><br><script>function myFunction(){var table = document.getElementById("myTable");

The idea is that a number of managers can be added, but I cannot find a way to add it that when returning to the controller brings the information of Company Responsible .

Basically the idea is to pass an array from the view to the controller, but I have the problem handling the ICollection

Thanks a lot!

    }

When I map   the error is coming is as follows

AutoMapper.AutoMapperMappingException: 'Error mapping types.'

Hi devs,

A week ago I decided to make the switch, I made Windows my secondary OS, and Linux - the main one. I love Linux, but I am experiencing an issue. I started learning ASP.NET Core maybe like half an year ago. I created a small forum app with Visual Studio on ASP NET Core 3.1. It also uses azure key vault. It worked perfectly under Windows, but under Linux it doesn't work as expected.

Summary of the problem I am having:

When I try to connect to Azure key vault under Windows it works, because of VS, but under Linux it doesn't. It throws exception, that it couldn't get a token. I am familiar that under Linux it uses Azure CLI(I have it installed and I am logged in). The shell command for getting a vault token also works. But when i run my code with dotnet run it just doesn't work. For IDE I am using Rider, but that's not important.

Error I am receiving:

Unhandled exception. Microsoft.Azure.Services.AppAuthentication.AzureServiceTokenProviderException: Parameters: Connection String: RunAs=App;, Resource: https://vault.azure.net, Authority: https://login.windows.net/4a06d40c-e447-42be-baef-dd0421ed10bd.

namespace ForumSystem.Web
{
    using Microsoft.AspNetCore.Hosting;
    using Microsoft.Azure.KeyVault;
    using Microsoft.Azure.Services.AppAuthentication;
    using Microsoft.Extensions.Configuration;

                if (!string.IsNullOrEmpty(keyVaultEndpoint))

                    var keyVaultClient = new KeyVaultClient(
                        new KeyVaultClient.AuthenticationCallback(
                            azureServiceTokenProvider.KeyVaultTokenCallback));
                    builder.AddAzureKeyVault(
                    keyVaultEndpoint, keyVaultClient, new DefaultKeyVaultSecretManager());
                }
            })
                .ConfigureWebHostDefaults(
                    webBuilder =>
                    {
                        webBuilder.UseStartup<Startup>();
                    });

        private static string GetKeyVaultEndpoint() => "https://myKeyVault.vault.azure.net/";
    }
}

The code I am using is copy pasted from docs and I added the RunAs=App connection string.

What I tried:

I assured that the Azure CLI is installed, logged into the account and that I am running the latest stable version of the CLI and .NET Core 3.1. I tried reinstalling Linux. Also I tried running the code with and without the connection string in the AzureServiceTokenPorvider. I just recieve a similar error in which I am told that it tried the 3 different ways and on the third(Azure CLI) it just says that the token couldn't be acquired. Of course I also tried reinstalling .NET Core and Azure CLI several times with no success.

I will be happy to provide any additional info if needed :)

I have a drop down that's populated from a database table and its corresponding model. Works great!

However, every time I return to the controller, I have to read the table again.  This seems inefficient at best.  I tried to overcome this by creating a static object, but every time a View is rendered, the object is disposed and an error is thrown by the controller.  How do I overcome this?

Here is my failed code:

// List of bagtypes. Only want to get these once
public static DbSet<Bagtypes> bagtypes {get; set;} = null;

... Other Controller code

[HttpGet]
public async Task<IActionResult> Edit(int? id, bool? copy)
{

// other edit stuff here


if (bagtypes == null) // Only do this the first time through...

{

bagtypes = _db.Types;

}

bvm.TypeOfBag = bagtypes;

return View(bvm);

}

Hi all,

I'm trying to implement dynamic OrderBy using Dynamic LINQ in an Asp Core 3.1 project, here's what I have:

orderedList = filters.SortDirection.ToLower(CultureInfo.CurrentCulture) == "asc"
                    ? orderedList.OrderBy(filters.SortBy).ToList()
                    : orderedList.OrderByDescending(filters.SortBy).ToList();

I note that on the Nuget page (https://www.nuget.org/packages/System.Linq.Dynamic.Core/) it specifies Asp Core 2.1, does anyone know if this can or cannot be used in 3.1 and if not is there an alternative way of achieving this in 3.1?

ASP.NET CORE VS 2019 NuGet "jquery.UI.Combined" where are the files?

I installed the NuGet jquery.UI.Combined but nothing appears in the wwwroot. I also Added jquery ui with the "Add Client Side Library" tool in VS and it added this to my libman.json:
,
{
"library": "jqueryui@1.12.1",
"destination": "wwwroot/lib/jqueryui/"
}

But there is no jqueryui folder in the lib folder.

Thanks! (Confused in the Enterprise)
