Describe the bug

When retargeting the 3rd party applications to .NET10 with dotnet-sdk-10.0.100-preview.5.25272.110, it will throw below errors when running the app:

System.InvalidOperationException: IdentityRedirectManager can only be used during static rendering System.InvalidOperationException: 'RemoteNavigationManager' already initialized

Application Name: Blazor-Blogs
OS: Windows 10 22H2
CPU: X64
.NET Build Number: dotnet-sdk-10.0.100-preview.5.25272.110

Steps To Reproduce

Minimal Repro steps (Demo attached: BlazorAppDemo):
The machine has dotnet-sdk-10.0.100-preview.5.252722.110 installed.

  1. Create a default 9.0 blazor web project.

  2. Right click on Solution>Properties, Retarget framework selection 10.0.

  3. Add file to the root directory: IdentityRedirectManager. cs

        using Microsoft.AspNetCore.Components;
    namespace BlazorAppDemo
    {
        public class IdentityRedirectManager
        {
            private readonly NavigationManager _navigationManager;
            public IdentityRedirectManager(NavigationManager navigationManager)
            {
                _navigationManager = navigationManager;
            }
            public void RedirectTo(string uri)
            {
                uri ??= "";
                if (!Uri.IsWellFormedUriString(uri, UriKind.Relative))
                {
                    uri = _navigationManager.ToBaseRelativePath(uri);
                }
                _navigationManager.NavigateTo(uri);
                throw new InvalidOperationException($"{nameof(IdentityRedirectManager)} can only be used during static rendering.");
            }
        }
    }

  4. Register Service in Program.cs
    builder.Services.AddScoped<IdentityRedirectManager>();

  5. Remove the judgment of whether it is a development environment in Program.cs：

        app.UseHsts();```

  6. Modify Components/Pages/Home.razor page

        @page "/"
    @inject IdentityRedirectManager Redirector
    @code {
        protected override void OnInitialized()
        {
            RedirectManager.RedirectTo("/dashboard");
        }
    }
    Modify Components/Pages/Error.razor page
    @page "/Error"
    @inject NavigationManager Navigation
    <PageTitle>Home</PageTitle>
    @code {
        protected override void OnInitialized()
        {
            var method = typeof(NavigationManager).GetMethod("Initialize", System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance);
            method?.Invoke(Navigation, new object[] { "https://localhost:5001/", "https://localhost:5001/" });
        }}

  7. Publish app.

  8. Cd \bin\release\net10.0\publish

  9. Launch "BlazorAppDemo.exe"

  10. Open the website: http://localhost:5000/.

.NET Version

10.0.100-preview.5.25272.110

Anything else?

App Repro steps：

Please check the repro machine from devdiv bug

The machine has dotnet-sdk-10.0.100-preview.5.252722.110 installed.

1.Update the "C:\Users\test01\Desktop\App\Blazor-Blogs\BlazorBlogs.runtimeconfig.json" to run against with .NET 10:

{
  "runtimeOptions": {
    "tfm": "net9.0",
    "frameworks": [
      {
        "name": "Microsoft.NETCore.App",
        "version": "10.0.0-preview.5.25272.110"
      },
      {
        "name": "Microsoft.AspNetCore.App",
        "version": "10.0.0-preview.5.25272.110"
      }
    ],
    "configProperties": {
      "System.GC.Server": true,
      "System.Reflection.Metadata.MetadataUpdater.IsSupported": false,
      "System.Reflection.NullabilityInfoContext.IsSupported": true,
      "System.Runtime.Serialization.EnableUnsafeBinaryFormatterSerialization": false
    }
  }
}
}

  1. Launch application from "C:\Users\test01\Desktop\App\Blazor-Blogs\BlazorBlogs.exe".

  2. Open the website: http://localhost:5000/.

  3. Input "appcompat@163.com" in Email.

  4. Get password from "C:\Users\test01\Desktop\Password.txt" , then input into the password.

  5. Click Login.

Expected Result: log in successfully.

Actual Result: log in failed with below error.

We have it documented:
https://learn.microsoft.com/en-us/aspnet/core/blazor/tutorials/movie-database-app/part-2?view=aspnetcore-9.0&pivots=vs#test-the-app

https://learn.microsoft.com/en-us/aspnet/core/release-notes/aspnetcore-10.0?view=aspnetcore-9.0#navigationmanagernavigateto-no-longer-throws-a-navigationexception

Calling NavigationManager.NavigateTo during static SSR no longer throws a NavigationException. Instead, it behaves consistently with interactive rendering by performing the navigation without throwing an exception.
Code that relied on NavigationException being thrown should be updated. For example, in the default Blazor Identity UI, the IdentityRedirectManager previously threw an InvalidOperationException after calling RedirectTo to ensure it wasn't invoked during interactive rendering. This exception and the [DoesNotReturn] attributes should now be removed.
