The type or namespace name 'MauiUIApplicationDelegate' could not be found Microsoft.AspNetCore.Components.WebView.Maui 8.0.7

[garcia252]

Description

We just upgraded Microsoft.AspNetCore.Components.WebView.Maui and Microsoft.Maui.Controls to 8.0.7. When compiling it gives us the error:

/Platforms/iOS/AppDelegate.cs(6,32): error CS0246: The type or namespace name 'MauiUIApplicationDelegate' could not be found (are you missing a using directive or an assembly reference?)

No other code changes were made whatsoever. Recently we used 8.0.6 and it compiled fine.

Steps to Reproduce

Upgrade Microsoft.AspNetCore.Components.WebView.Maui and Microsoft.Maui.Controls to 8.0.7

I think this is tied in with #20565 , this is the actual error I'm getting on my Azure DevOps build agents, with the behavior described in the other issue when installing workloads. Local builds are all working fine after force-cleaning and restore/rebuild after updating to the latest nuget packages.

Are you installing via the CLI or are you using Visual Studio?
If you update to the latest Visual Studio this should work fine.

What version of the sdk are you on?
dotnet --info

@PureWeen this is in Azure DevOps Pipeline. We are using SDK Task to use .NET 8.x, we also check "Include Preview Versions"

@bengavin the workloads we are installing are "install ios maccatalyst tvos macos maui wasm-tools". This has worked great before.

@garcia252 - Yes, we are in a similar boat, there is -something- corrupted/invalid in the mapping for the new 8.0.200 workloads, at least as they are downloaded from the macos-13 hosted DevOps build agent. We haven't enabled preview versions, and we've updated out build in the short term to lock into 8.0.101, but it would be handy NOT to have to do that :)

Please see #20600

Duplicate of #20600 and a fix is available for the hosted build agents without the need for any other changes.
