Exceptions on AuthorizeView net8.0p7

[johnW-ret]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

In server render mode, using AuthorizeView results in a NullReferenceException in Microsoft.AspNetCore.Components.Server.Circuits.RemoteJSRuntime.EndInvokeDotNet upon the component being rendered. In wasm render mode, it results in an InvalidOperationException in the browser. Both exceptions

Expected Behavior

The component to render according to the logic of AuthorizeView.

Steps To Reproduce

Toggle @rendermode to Server or WebAssembly in the provided fork.

Exceptions (if any)

Microsoft.AspNetCore.Components.WebAssembly.Rendering.WebAssemblyRenderer[100]
Unhandled exception rendering component: Authorization requires a cascading parameter of type Task. Consider using CascadingAuthenticationState to supply this.
System.InvalidOperationException: Authorization requires a cascading parameter of type Task. Consider using CascadingAuthenticationState to supply this.

.NET Version

8.0.100-preview.7.23376.3

Anything else?

I apologize if this is a configuration issue on my end. It occurred when trying to get Microsoft.Identity.Web to work in net8.0, so this is my attempt to create a minimal repro - and it still occurs.

[DM-98]

Your repro doesn't have builder.Services.AddCascadingAuthenticationState(); in the server project. Could you add it and try again? This is the new way to register cascading parameters to the root of the app.

[SteveSandersonMS]

Thanks @DM-98.

@johnW-ret Please try the suggestion above and let us know how it goes. AddCascadingAuthenticationState is required as per the exception message.

Hi @johnW-ret. We have added the "Needs: Author Feedback" label to this issue, which indicates that we have an open question for you before we can take further action.

[johnW-ret]

Thank you for your help and support. I apologize for the delay in getting back.

I have tested @DM-98's suggestion on both repos and encountered no issues. This issue is safe to close.

On a side note, what's a great way to keep up with API changes for preview releases? I've only been monitoring #44984 and the official release blog posts.

Official release blog posts are a good way to learn about upcoming changes.
