Modular Application with Identity gives 500 error

[upaelfid]

Im creating a modular application. When I reference the module without using Microsoft.AspNetCore.Identity.UI I can see the resources that the referenced module uses. But when I add Microsoft.AspNetCore.Identity.UI then I get 500 errors for all the resources that are referenced by the module. When I go inspect the element that is not being served I get:

An unhandled exception occurred while processing the request.
ArgumentException: Value cannot be null or empty. (Parameter 'areaName')
Microsoft.AspNetCore.Builder.ControllerEndpointRouteBuilderExtensions.MapAreaControllerRoute(IEndpointRouteBuilder endpoints, string name, string areaName, string pattern, object defaults, object constraints, object dataTokens)

Any help would be greatly appreciated

The razor class library with area is not supported with orchard core modular framework #4247 #10230 #10287

Thank you Niraj! Do you know if there a way to add identity to my module without the cms?

I have not tried but you could implement IApplicationFeatureProvider<ViewsFeature> for Identity Assembly and register in your Program.cs

Not having any luck yet. I am creating a module that has an [Authorize] attribute on one of its controllers, this way a user has to sign in to edit an item. Do you know of a way of getting around the razor class library issue?

[ns8482e]

I think the issue might be Identity area not matching with assembly.

Try this---

• add Microsoft identity ui reference to mvc web
• create a mvc module named "Identity" and add reference to mvc web
• Run app

Thank you so much for responding! Here are the steps I am taking.
-I create a .net core web app mvc
-A controller called CoreImg
-A view called index. The view has .jpg image
-I add OrchardCore.Module.Targets as a reference

-I create a project called Website
-Add OrchardCore.Application.Mvc.targets
-set up the Program.cs with AddOrchardCore().AddMvc();
and the useOrchardCore();

when I go to https://localhost/CoreImage/Index I see the .jp image

If I rewrite everything as above but for the Website part, I add the Identity framework, and add [Authorize] to the CoreImg controller... When I got to https://localhost/CoreImage/Index it asks me to login with my credentials. I log in but now the Image isnt being served and when I inspect it it gives me a 500 error

500 error might be due to missing authorization in your orchard pipeline

@upaelfid This is how I made it to work.

1. Create a dummy module Identity

 dotnet new ocmodulemvc -o Identity

2. Create a Modular module Module1. Create your controller here in this module with [Authorize] attribute.

dotnet new ocmodulemvc -o Module1

3. Create a ASP.NET Core web application ( from VS or using following command line) and add project references and package references as below.

dotnet new ocmvc -o ModularWebApp

  <ItemGroup>
    <PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="8.0.2" />
    <PackageReference Include="Microsoft.AspNetCore.Diagnostics.EntityFrameworkCore" Version="8.0.2" />
    <PackageReference Include="Microsoft.AspNetCore.Identity.EntityFrameworkCore" Version="8.0.2" />
    <PackageReference Include="Microsoft.AspNetCore.Identity.UI" Version="8.0.2" />
    <PackageReference Include="OrchardCore.Application.Mvc.Targets" Version="1.8.2" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.Tools" Version="8.0.2" />
  </ItemGroup>

  <ItemGroup>
    <ProjectReference Include="..\Identity\Identity.csproj" />
    <ProjectReference Include="..\Module1\Module1.csproj" />
  </ItemGroup>

5. Update Program.cs as following

using Microsoft.AspNetCore.Identity;
using Microsoft.EntityFrameworkCore;

var builder = WebApplication.CreateBuilder(args);

builder.Services
    .AddOrchardCore()
    .AddMvc()
     // Orchard Specific Pipeline
     .ConfigureServices(services =>
     {
		 // Add services to the container.
		 var connectionString = builder.Configuration.GetConnectionString("DefaultConnection") ?? throw new InvalidOperationException("Connection string 'DefaultConnection' not found.");
		 services.AddDbContext<ApplicationDbContext>(options =>
			 options.UseSqlServer(connectionString));
		 services.AddDatabaseDeveloperPageExceptionFilter();

		 services.AddDefaultIdentity<IdentityUser>(options => options.SignIn.RequireConfirmedAccount = true)
			 .AddEntityFrameworkStores<ApplicationDbContext>();

	 })
     .Configure((app, routes, services) =>
     {
		 app.UseAuthorization();
	})
;

var app = builder.Build();

if (!app.Environment.IsDevelopment())
{
    app.UseExceptionHandler("/Error");
    // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
    app.UseHsts();
}

app.UseHttpsRedirection();

app.UseStaticFiles();

app.UseOrchardCore();

app.Run();

Thank you so much for giving me this direction. Ive been wrestiling trying to duplicate this. Do you add the scaffolded Identity item to the dummy "Identiy" module or do you add it to the ModularWebApp?

[ns8482e]

I used OC Identity module which as nothing in it. It allows OC to be aware of Identity module with area Identity.
Identity area is already exists in Identity UI, so OC will serve UI from Identity UI.

All Identity related Data are in main WebApp

That works like MAGIC!
