Description
[ORIGINATES FROM https://github.com/dotnet/templates/issues/723]
dotnet new command never finishes and seems to fall in an infinite loop during parameter condition evaluation with net8 preview 2.
The same template works properly with latest net7 builds.
Steps to repro
Install .NET 8 Preview 2
dotnet new install Uno.Templates
dotnet new unoapp -o testapp
The command fails to finish and is stuck in the following expression (original template source):
this Cannot obtain value of the local variable or argument because it is not available at this instruction pointer, possibly because it has been optimized away. Microsoft.TemplateEngine.Orchestrator.RunnableProjects.Macros.EvaluateMacro
