I am not sure about RequiredRouteConstraint use. The definition sais“Constraints a route parameter that must have a value.” and”This constraint is primarily used to enforce that a non-parameter value is present during URL generation.”.

The route normally without parameter specified would not be matched if it is not optional parameter or if the default route not comply this case. So appending:required constraint to route parameter (e.g. {name:required}) seems useless to me.

How does look like example of RequiredRouteConstraint common use?

Hi,

I am using ASP.Net Core and Entity Framework 6.0.

I am trying to get the windows user info, which will be checked against the application database for authorization access.

I am having problems with the following script:

BaseController.cs

public class BaseController: Controller
{

     public override void OnActionExecuting(ActionExecutingContext filterContext)
     {
            if (HttpContext.User == null || HttpContext.User.Identity.AuthenticationType != "Forms") 
            {
                    //return null; 
             }

             var identity = HttpContext.User.Identity;
      }
}


web.config

<configuration>
  <system.web>
    <authentication mode="Windows" />
    <authorization>
       <deny users="?"/>
    </authorization>
  </system.web>
</configuration>

When I run the application,

HttpContext.User.Identity.AuthenticationType = "" and HttpContext.User.Identity = "".  How can I get the current windows username?

Thanks,

I have an ASP.NET Core 1.1 web application (simple web API) and an Angular client application. I'm using Azure Active Directory B2C as my auth provider and I've deployed my applications to three separate Azure Web Apps using VS2017 publishing.

1. Client - Angular client
2. ApiCore - The ASP.NET Core 1.1 web application published with the TargetFramework netcoreapp1.1
3. ApiFramework - The ASP.NET Core 1.1 web application published with the TargetFramework net462

Client has a simple config that allows me to change the URI for its API service making it easy to toggle between CoreApi and FrameworkApi backing services.

If the Client's API URI is set to ApiCore's URI everything is working beautifully. Users have access to both secure and open resource when logged in and receive 401 accessing secure resources if not. However, setting the Client's API URI to the ApiFramework URI causes the user to receive 401 accessing secured resources regardless of login status. Open resources continue to function normally.

To be clear the only difference in the publishing of these two web applications is the value of the TargetFramework element in the .csproj file. The code and all configuration is identical.

The following is my .csproj file contents. I simply change the commented TargetFramework line and deploy using VS2017 publishing where I have a profile for each target (shown is for the ApiCore publish).

I am developing ASP.NET Core web api. here i have a situation like i have to use multiple get functions which get data from sql server db. So for that i'm doing custom attribute routes. below are my codes

[Route("api/[controller]")]
public class MeController : Controller
{
    private readonly ITechRepository _tech;
    private readonly IPageOptions _page;
    public MeController(ITechRepository tech,IPageOptions page)
    {
        _tech = tech;
        _page = page;
    }

   [Route("getTech")]
    public IEnumerable<TechStack> Get()
    {
        return _tech.getAll();
    }
    [Route("getOptions")]
    public IEnumerable<PageControl> getOptions()
    {
        return _page.getOptions();
    }
     //GET api/values/5
    [HttpGet("{id}")]
    public int Get(int id)
    {
        return id;
    }
}

The above routes are works well in VS IIS Express and this is that url http://localhost:51889/api/me/gettech

But when i publish this api in IIS 10. The getTech and getOptions were not working it producing 404 error and also [HttpGet("{id}")] is working in both.

Can anybody help on this...

Hello,

   I am having two issues with the Select tag helper in my project.  In both the Edit and Create views the validation for the Select tag helper is not working.  Also the view is not setting to the selected option, as it seems to be stripping it away when displaying the view.  Each view has multiple select tag helpers, pulling data from multiple tables.

So here is my controller for both the Create and Edit. 

        private readonly LotroModel _db;               public CharactersController(LotroModel db)        {            _db = db;        }
        public IActionResult Create()        {            var serverList = _db.Database.SqlQuery<ServersNamesListViewModel>("SELECT Server_ID AS ServerID, Server_Name AS ServerName FROM dbo.Server").ToList();            var professionList = _db.Database.SqlQuery<ProfessionNamesListViewModel>("SELECT Profession_ID AS ProfessionID, Profession_Name AS ProfessionName FROM dbo.Profession").ToList();            var levelList = _db.Database.SqlQuery<LevelNumbersListViewModel>("SELECT Level_ID AS LevelID, Level_Number AS LevelNumber FROM dbo.Level").ToList();            var classList = _db.Database.SqlQuery<ClassNamesListViewModel>("SELECT Class_ID AS ClassID, Class_Name AS ClassName FROM dbo.Class").ToList();            var raceList = _db.Database.SqlQuery<RaceNamesListViewModel>("SELECT Race_ID AS RaceID, Race_Name AS RaceName FROM dbo.Race").ToList();            var sList = new List<SelectListItem>();            var pList = new List<SelectListItem>();            var lList = new List<SelectListItem>();            var cList = new List<SelectListItem>();            var rList = new List<SelectListItem>();            foreach( ServersNamesListViewModel sn in serverList )            {                sList.Add(new SelectListItem { Text = sn.ServerName, Value = sn.ServerID.ToString() });            }            foreach( ProfessionNamesListViewModel pn in professionList )            {                pList.Add(new SelectListItem { Text = pn.ProfessionName, Value = pn.ProfessionID.ToString() });            }            foreach( LevelNumbersListViewModel ln in levelList )            {                lList.Add(new SelectListItem { Text = ln.LevelNumber.ToString(), Value = ln.LevelID.ToString() });            }            foreach( ClassNamesListViewModel cn in classList )            {                cList.Add(new SelectListItem { Text = cn.ClassName, Value = cn.ClassID.ToString() });            }            foreach( RaceNamesListViewModel rn in raceList)            {                rList.Add(new SelectListItem { Text = rn.RaceName, Value = rn.RaceID.ToString() });            }            var character = new CharacterViewModel()            {                ServersList = sList,                ProfessionList = pList,                LevelList = lList,                ClassList = cList,                RaceList = rList            };            return View(character);        }        // POST: Characters/Create        // To protect from overposting attacks, please enable the specific properties you want to bind to, for        // more details see http://go.microsoft.com/fwlink/?LinkId=317598.        [HttpPost]        [ValidateAntiForgeryToken]        public async Task<IActionResult> Create( CharacterViewModel returnedView, Character character)        {            if (ModelState.IsValid)            {                character.Char_First_Name = returnedView.Char_First_Name;                character.Char_Last_Name = returnedView.Char_Last_Name;                character.Char_Gender = returnedView.Char_Gender;                character.ServerServer_ID = Convert.ToInt32(returnedView.ServersList.Select(x => x.Value));                character.Profession_Profession_ID = Convert.ToInt32(returnedView.ProfessionList.Select(x => x.Value));                character.Level_Level_ID = Convert.ToInt32(returnedView.LevelList.Select(x => x.Value));                character.Class_Class_ID = Convert.ToInt32(returnedView.ClassList.Select(x => x.Value));                character.Race_Race_ID = Convert.ToInt32(returnedView.RaceList.Select(x => x.Value));                _db.Characters.Add(character);                await _db.SaveChangesAsync();                return RedirectToAction("Menu", "Menu");            }                       //This is not returning the dropdowns, need the returnView values as selected.                          return View(returnedView);        }        public async Task<IActionResult> Edit(int?

Here is the View Model I am working with, plus a view model for the selectlistitem, all the selectlistitem view models are relatively the same, with just a change of data.

public class CharacterViewModel    {        [HiddenInput]        public int CharID { get; set; }        [Required]        [StringLength(20)]        [Display(Name = "First Name")]        public string Char_First_Name { get; set; }        [StringLength(20)]        [Display(Name = "Last Name")]        public string Char_Last_Name { get; set; }        [Required]        [StringLength(7)]        [Display(Name = "Gender")]        public string Char_Gender { get; set; }        [Required]        [Display(Name = "Server")]        public List<SelectListItem> ServersList { get; set; }        [Display(Name = "Profession")]        public List<SelectListItem> ProfessionList { get; set; }        [Required]        [Display(Name = "Level")]        public List<SelectListItem> LevelList { get; set; }        [Required]        [Display(Name = "Class")]        public List<SelectListItem> ClassList { get; set; }        [Required]        [Display(Name = "Race")]        public List<SelectListItem> RaceList { get; set; }    }

public class ServersNamesListViewModel    {        [Key]        public int ServerID { get; set; }        [Required]        [Display(Name = "Server Name")]        public string ServerName { get; set; }
        public bool IsSelected { get; set; }    }

Lastly here are the two views, with the global portion of my javascript:

What I see in the development tools for the web browsers is essentially the same, no errors show in the console.  I am getting 200 OKs in the network section, but in my DOM, I see:

If I look at the output from Visual Studio while debugging this section I see this:

Disabled: false

Group: null

Selected: true

Text: Brandywine

Value: 4

All others in that listing return false on the selected.  This is essentially the same for all the other lists.  What I get on the View is the "Select a Server" showing.  So how do I get this to display the selected value when displaying the page.  And with the validation, it returns the Select a Server as valid, I would guess because this never shows that these dropdown lists are invalid.  I could leave everything blank on the screen for the Create and I only get two validation errors, while I should be getting 6 errors.

Does anyone see what I am doing wrong?

I'm using a partial view to create a security question and answer view using a model. Besides the issue of naming each one with a index number. That is a whole seperate issue all together.
I want 3 security questions and answers. I add the partial view 3 times to create 3 security questions and answers. Of those 3 only the the first security question and answer is decorated with
model requirements. The next 2 is missing the model requirements. I decided this is a [BUG]. At some point the web controls get decorated with the model requirements. For some reason it only does one
and ignores the reset.

What is going on here and why is this not working failing

Model:

public class QNAViewModel
{
     [Required(ErrorMessage = "The question field is required")]
     public String Question { get; set;}

     [Required(ErrorMessage = "The answer field is required")]
     [StringLength(250, ErrorMessage = "The {0} must be at least {2} and at max {1} characters long.", MinimumLength = 3)]
     public String Answer { get; set; }

}

Partial View:

@model MyNameSpace.Models.ProfileViewModels.QNAViewModel
@{
    string qId = String.Format("Question{0}", ViewData["Index"]);
    string aId = String.Format("Answer{0}", ViewData["Index"]);
}<div class="form-group"><label asp-for="Question" for="@qId" class="col-md-2 control-label"></label><div class="col-md-5"><select asp-for="Question" id="@qId" name="@qId" class="form-control" asp-type="securityquestion"></select><span asp-validation-for="Question" data-valmsg-for="@qId" class="text-danger"></span></div></div><div class="form-group"><label asp-for="Answer" for="@aId" class="col-md-2 control-label"></label><div class="col-md-5"><input asp-for="Answer" id="@aId" name="@aId" class="form-control" /><span asp-validation-for="Answer" data-valmsg-for="@aId" class="text-danger"></span></div></div>

Is there a "proper" way to setup model binding for dynamically adding, editing, and deleting elements in .NET Core? I came across this article (https://www.codeproject.com/Tips/766214/List-Model-Binding-in-MVC) which goes over the concept I'm trying to build. I'm new to ASP.NET MVC and I wanted to see if anyone had suggestions or examples on a good way to handle something like this.

Thanks in advance for any help.

Hi,

I want to write application separated to 3 parts. Client Service, Service, Web.

Let's say we have for example 5 computers and 1 server. Each computer will run Client Service. Server will run Service and Web.
I thinking of Client Service as Windows Service Project. Service as WCF Service and Web as ASP.NET Core (.NET Framework).

Client Service will collect data about users and send it to WCF Service to write it to db.
Web will work as data viewer with graphs etc.

So what's the question?
Currently thinking of if its possible for WCF to connect to ASP.NET Core or is there a better solution instead of WCF? I think WebAPI is not great solution for this.
Also do you think its better to design for each database table own manager for add/edit/delete etc. or share through WCF DatabaseContext to Web for display or make own DatabaseContext for Web? Or Just share from WCF ConnectionString?

I don't have much experience in designing in this concept. So better to ask someone who's experienced :)

Thanks.

Hi!

I'm trying to create a class library in my solution, and I want it to access the Environment Variable, so I can choose the correct db connection string.  Does anybody know how to do that?  Since my main project is dependent on the class library, I can't make the class library dependent on the main project to access that variable.

Thanks!

Hi,

How we can ridirect the current page When user access the Unauthorized content. 

Index Page

When I click on the "Click" button in Index Page, Then It will redirect to Home controller.

<div class="row"><div class="col-md-12"><h1>Welcome to ASP.NET Core Identity !!</h1><p>Security !!</p><a asp-controller="Home" asp-action="Home" class="btn btn-success">Click</a></div></div>

Home Controller

We already set Authorize in Home Action in Home Controller. So the click event will fire Home Action method. But it showing blank page !! 401 

using Microsoft.AspNetCore.Authorization;
using Microsoft.AspNetCore.Mvc;
using RegistrationForm.Models;

namespace RegistrationForm.Controllers.WebApp
{
    public class HomeController : Controller
    {

        public HomeController(IRegRepository repository)
        {
            _repository = repository;
        }

        [Authorize]
        public IActionResult Home()
        {
            var data = _repository.GetAllRegistrations();

I have an ASP.NET Core application running behind IIS in production that is not freeing memory on its own until the application pool recycles itself.  Every request causes the memory to increase.  

I am able to reproduce this with a fresh ASP.NET core application using Visual Studio 2017 with the ASP.NET Core Web API template.  I created the following method and called it from postman about 100 times:

namespace WebApplication3.Controllers
{
    [Route("")]
    public class ValuesController : Controller
    {
        [HttpGet]
        public IEnumerable<string> Get()
        {
            var message = "test";
            return Enumerable.Repeat(message, 100000);
        }
    }
}

I did a publish build and launched the application from the command line.

The memory usage goes up and is never released:

Here is my dotnet version

PS C:\Windows\system32> dotnet --version
1.0.0

I expect the memory to go down after the requests are done being served.  Does anybody have any idea what is going on?

I am trying to just do an controller scaffolding on a ASP.NET Core application I and I get the following error

Unhandled Exception: System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.VisualStudio.Web.CodeGeneration.Utils, Version=1.1.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'. The system cannot find the file specified.

I looked on Google but they are not many references about VS2017 yet.

Thanks

Hi,

I have a Aspx page in that user control is loaded based on the user selection. Here i want to display the page title from Usercontrol ascx file (not from code behind). how can i achieve this. Please help.

Hello

When I use VS Community 2017 and try and install some new dependencies via NuGet Package manager (specifically, Razor tools, Static file and MVC) I get the following error:

 Package Microsoft.AspNet.Razor 3.2.3 is not compatible with netcoreapp1.1 (.NETCoreApp,Version=v1.1). Package Microsoft.AspNet.Razor 3.2.3 supports: net45 (.NETFramework,Version=v4.5)
One or more packages are incompatible with .NETCoreApp,Version=v1.1.

I've clicked on the cog next to the package source and clicked the update button (so I have the most resent package list).

I'm trying to load these files as I am following an online course, and the next step is to load Microsoft.AspNetCore.Razor.Tools , Microsoft.AspNetCore.StaticFiles and Microsoft.AspNetCore.Mvc ( the video instructor is using a lesser version that 2017.. so is that the problem ?).

The tutor goes on to talk about editing the project.json file ( which is now superseded by the csproj file ) to load them...

can anyone help shed some light for me ?

thanks in advance

I have a number of form tags that look similar:

<form asp-area=@ViewBag.Area asp-controller=@ViewBag.Controller asp-action=@ViewBag.Action asp-route-returnurl="@ViewData["ReturnUrl"]" method="post" class="form-horizontal">

It would be nice if I put everything in "<form ... >" into a "super ViewBag" or partial view so I have it all in one place in case of changes. I've unsuccessfully tried a number of ways. Any ideas?

I'm currently trying to get signing keys from Azure Active Directory based on the signing key rollover guide over at Microsoft docs in order to authenticate HTTP requests on an ASP.NET Core Web API endpoint I'm developing.

Although I migrated the source code shown in the article it doesn't seem like some references and classes are available in ASP.NET Core web apps such as System.IdentityModel.Metadata and classes like X509SecurityToken, MetadataSerializer, EntityDescriptor and X509RawDataKeyIdentifierClause.

Source code with types not found

I already searched on NuGet, but it doesn't seem like packages are available for System.IdentityModel and I'm not able to reference system assemblies in ASP.NET Core neither.

Which libraries shall I use in ASP.NET Core instead?
