Cannot set RC2 to build x86 target
Hi there,
I have an ASP.Cet Core Framework app using RC2.
I need to include a 32 bit foreign com assembly - check: made nuget package, added to local repo and added to project from there.
Now I need to generate x86 web app - with x64 build I see BadImageFormatException for that assembly.
The issue: I can not set build x86 in configuration manager. I can add x86 platform (already exists when add new is checked), but after close and reopen configuration manager the Any Cpu platform is selected and the x64 build is run.
Is there something missing to be installed on Win10x64 for x86 target builds, or general RC2 issue?
Thanks
Bo

JsonOutputFormatter override
Hi,
I wrote a custom JsonOutputFormatter in asp.net core rc2. I am trying to migrate to asp.net core and I can see that I need a constructor(JsonSerializerSettings serializerSettings, ArrayPool<char> charPool) in the class that overrides JsonOutputFormatter.
How can I get these settings?
Thanks

ViewComponent InvokeAsync function doesn't take 3 arguments
Hi,
I am in Rich Anderson's View Component Tutorial. However, when I ran the code, I got an
/Views/ToDo/Index.cshtml
No overload for method 'InvokeAsync' takes 3 arguments
34. @await Component.InvokeAsync("PriorityList", 2, false)Well, I follow it step by step, this is totally against what the tutorial says. It says the InvokeAsync function "can take an arbitrary number of arguments." What have happened? Here is my ViewComponent class
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using StarterComponentView.Data;
using StarterComponentView.Models;
using Microsoft.AspNetCore.Mvc;
namespace StarterComponentView.ViewComponents
{
[ViewComponent(Name = "PriorityList")]
public class PriorityListViewComponent: ViewComponent
{
private readonly ApplicationDbContext db;
public PriorityListViewComponent(ApplicationDbContext context)
{
db = context;
}
public async Task<IViewComponentResult> InvokeAsync(int maxPriority, bool isDone)
{
var items = await GetItemsAsync(maxPriority, isDone);
return View(items);
}
private Task<List<ToDoItem>> GetItemsAsync(int maxPriority, bool isDone)
{
return db.ToDo.Where(x => x.IsDone == isDone &&
x.Priority <= maxPriority).ToAsyncEnumerable().ToList(); //.ToListAsync();
}
}
}
Here is the calling View
@using StarterComponentView.Models
@model IEnumerable<ToDoItem><h2>ToDo Starter</h2><table class="table"><tr><th>
@Html.DisplayNameFor(model => model.IsDone)</th><th>
@Html.DisplayNameFor(model => model.Priority)</th><th>
@Html.DisplayNameFor(model => model.Name)</th><th></th></tr>
@foreach (var item in Model)
{<tr><td>
@Html.DisplayFor(modelItem => item.IsDone)</td><td>
@Html.DisplayFor(modelItem => item.Priority)</td><td>
@Html.DisplayFor(modelItem => item.Name)</td></tr>
}</table><div>
@await Component.InvokeAsync("PriorityList", 2, false)</div>And here is the ViewComponent's view section
@model IEnumerable<StarterComponentView.Models.ToDoItem><h3>Priority Items</h3><ul>
@foreach (var todo in Model)
{<li>@todo.Name</li>
}</ul>I hate it when myself just copy / paste and the tutorial code doesn't work

problems with visual studio 2015 and asp.net core
After upgrading to vs2015 update 3 whenever I am building an asp.net core project and there is an error vs does not show it. Instead if I go to cmd and type dotnet build the error comes up at the same time in VS. Also If I delete bin folder manually from windows explorer and build from vs bin\Debug is produced and it is empty.

working with database first in Asp.Net Core
I want to learn Asp.Net Core since it is now RTM. But I am not familiar yet how to work with existing database. In the docs there is an example how to import an database into the project http://bit.ly/2980y46, but it doesn't satisfy my needs and it's just for a specific scenario (the tutorial is for the RC2, not for the RTM, even while the changes are small as much as I see). I want to use also the authentication that Asp.Net gives me, and combine it with the existing database. I want to work with specific tables. In earlier versions of Asp.Net it was very easy to work with existing databases, by just adding an Ado.Net Data Entity and choosing what I need. So, can someone please help me how to work with existing database in Asp.Net Core, and mixing the identity user tables into the database and so on.

No database provider has been configured for this DbContext
Hi,
I got an error message of
InvalidOperationException: No database provider has been configured for this DbContext. A provider can be configured by overriding the DbContext.OnConfiguring method or by using AddDbContext on the application service provider. If AddDbContext is used, then also ensure that your DbContext type accepts a DbContextOptions<TContext> object in its constructor and passes it to the base constructor for DbContext.
I suspect this is because I tried to add my DbContext into AspnetCore template IdentityDbContext. Here is my DbContext
public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options)
: base(options)
{
}
public ApplicationDbContext()
{
}
protected override void OnModelCreating(ModelBuilder builder)
{
base.OnModelCreating(builder);
// Customize the ASP.NET Identity model and override the defaults if needed.
// For example, you can rename the ASP.NET Identity table names and more.
// Add your customizations after calling base.OnModelCreating(builder);
}
public DbSet<Product> Products { get; set; }
public DbSet<Cart> Carts { get; set; }
...
}Here is my Startup.cs
public IConfigurationRoot Configuration { get; }
// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
// Add framework services.
services.AddApplicationInsightsTelemetry(Configuration);
services.AddDbContext<ApplicationDbContext>(options =>
options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));
services.AddIdentity<ApplicationUser, IdentityRole>()
.AddEntityFrameworkStores<ApplicationDbContext>()
.AddDefaultTokenProviders();
..........
} and here is how I call my DbContext
ApplicationDbContext storeDB = new ApplicationDbContext();
I checked my database, after doing
dotnet ef migrations add Initials dotnet ef database update
my database has been created. What's the complaint about then?
Thanks!
