Cannot change <MauiVersion> in .csproj

[MeestorX]

Description

I receive the following error if I add <MauiVersion></MauiVersion> to my .csproj:

The type or namespace name 'MauiUIApplicationDelegate' could not be found (are you missing a using directive or an assembly reference?) [{.csproj file name}::TargetFramework=net8.0-maccatalyst]

Steps to Reproduce

Create the default Maui Hybrid app
Add the line <MauiVersion>{whatever version of Maui you're currently running or any other version}</MauiVersion>
Run for MacCatalyst

In my case, I have 8.0.6 installed and without <MauiVersion> it runs properly.
The ONLY value that I can put for <MauiVersion> is 8.0.0-rc.1.9171. Any other value will cause the above error. e.g.
<MauiVersion>8.0.0-rc.1.9171</MauiVersion>

This "version string" matches the workload version. I cannot specify any OTHER version of Maui within .csproj to allow me to test a newer build.

Use `dotnet workload search` to find additional workloads to install.

Is this the same issue?

Are you referencing the Nuget packages in your project?

    <ItemGroup>
        <PackageReference Include="Microsoft.Maui.Controls" Version="$(MauiVersion)" />
        <PackageReference Include="Microsoft.Maui.Controls.Compatibility" Version="$(MauiVersion)" />
        <PackageReference Include="Microsoft.AspNetCore.Components.WebView.Maui" Version="$(MauiVersion)" />
        <PackageReference Include="Microsoft.Extensions.Logging.Debug" Version="8.0.0" />
    </ItemGroup>

If you don't reference the nugets, changing MauiVersion will, I believe, change the Workload version. That's why it fails for you, since you only have that version installed. Also, you should really update to .NET SDK 8.0.1 and the newest Workloads (dotnet workload update), those are .NET 8.0 RC1 builds and are quite old.

Are you referencing the Nuget packages in your project?

Yes, those lines are still in there.
As I said, I just created the dotnet maui-blazor template (dotnet new maui-blazer) and only added the <MauiVersion> line to .csproj.

Also, you should really update to .NET SDK 8.0.1 and the newest Workloads (dotnet workload update), those are .NET 8.0 RC1 builds and are quite old.

I have run sudo dotnet workload update a few times. It doesn't make any changes. The version looks to be 8.0.100 in the workloads, but you can see I've got 8.0.6 for MauiControls.

So this is an SDK issue, not Maui? I noticed you moved it from Maui.

Looks like the problem became widespread!
