NotSupportedException: No IUserTwoFactorTokenProvider<TUser> named 'Default' is registered with .NET 5

[MikeAlhayek]

I am trying to use OrchardCore on a .net 5 project outside the CMS. After a user registers I get the following exception

NotSupportedException: No IUserTwoFactorTokenProvider named 'Default' is registered.

I tried adding the following setting to the startup

services.AddIdentity<User, Role>()
            .AddEntityFrameworkStores<ApplicationContext>()
            .AddDefaultTokenProviders();

and even tried

services.AddIdentity<User, Role>()
            .AddEntityFrameworkStores<ApplicationContext>()
            .AddTokenProvider<DataProtectorTokenProvider<User>>(TokenOptions.DefaultProvider);

But still get the same problem after the user registers.

I am using OrchardCore.Application.Mvc.Targets 1.0.0-rc2-15508

Here is the full stack trace

Can't really tell what is wrong if we don't see your entire code or at least some repro steps. Here is the PR for .NET 5. https://github.com/OrchardCMS/OrchardCore/pull/6999

@Skrypt the project can be found here https://github.com/CrestApps/CrestApps.Core

Ok so typically MVC app. Your HomeController will enter in conflict with OC setup page.

We don't have any implementation of IUserTwoFactorTokenProvider<TUser>, so the question is what component is registered in your app, or what settings, will ask for this service.
