.NET MAUI projects supported?

[dhindrik]

We have used CodeQL for our .NET MAUI app for a while. But last time it was running successful was 13th November. Since than it failed, even if we still was on .NET 8.

We get a lot of errors like this:
{APP_PATH}\obj\Release\net9.0-windows10.0.19041.0\win10-x64\generated\Microsoft.Maui.Controls.SourceGen\Microsoft.Maui.Controls.SourceGen.CodeBehindGenerator\App.xaml.sg.cs'.'

I guess it is because of code generation of XAML.

So is .NET MAUI projects supported? If I look at the docs I cannot see .NET MAUI there. I a look back and I can also see that we never had any issues reported even if the run succeed.

We have an requirement to run CodeQL on all our repositories, but if it is not supported for .NET MAUI projects we need to explain it for the managers and looking for options.

I've tried the following to reproduce your issue:

dotnet workload install maui
dotnet new maui --name maui1   
cd maui1
dotnet build -f net9.0-maccatalyst /t:rebuild

The above built the application successfully, so then I tried the below, which created a database:

codeql database create DB1 --language=csharp --command="dotnet build -f net9.0-maccatalyst /t:rebuild"

Could you give a bit more context on the errors that you see? Would you be able to provide a minimal repro of your issue?
