I am using MAUI blazor and making use of WebAuthenticator, it works fine for iOS and Android but not when running as Windows app.
If you look at this MS doc - Web Authenticator - .NET MAUI | Microsoft Learn it mentions that Windows is broken. Then you follow the link to GitHub issue 2702 - GitHub Issue 2702
This is marked Fixed by MicrosoftDocs/xamarin-docs#3455 - which is a fix for an Android issue - I am not sure I understand why this could be the solution.
Does anyone have WebAuthenticator working on Windows Maui? I have tried all the suggestions in the 2702 Issue including dotMorten solution and I always get the COMException error There are no remote procedure calls active on this thread. (0x800706BD).
I am not sure what to try next and hoping someone out there has had this error and found a fix?

Solomon Fried 1 Reputation point2022-10-30T15:55:22.213+00:00 Having the same issue. Trying to create a new app on Maui using the same login logic that I have for my Xamarin apps.
I think I will revert back to Xamarin until Maui is more mature.
