.NET 8 Preview 1

When installing .NET MAUI on win-arm64 machines, you might get the error:

Workload ID maui isn't supported on this platform.

To work around this, manually patch the WorkloadManifest.json files as mentioned here.

On macOS, if you encounter a build error related to mono-aot-cross:

An error occurred trying to start process '/usr/local/share/dotnet/packs/Microsoft.NETCore.App.Runtime.AOT.osx-x64.Cross.maccatalyst-x64/8.0.0-preview.1.23115.2/Sdk/../tools/mono-aot-cross'. Permission denied

To work around the issue, by making the file executable:

chmod +x /usr/local/share/dotnet/packs/Microsoft.NETCore.App.Runtime.AOT.osx-x64.Cross.maccatalyst-x64/8.0.0-preview.1.23115.2/tools/mono-aot-cross
