Release build fails for Mac and WASM

[trydalch]

Our application builds just fine in debug, but gets these errors when building in release:

System.Exception: Failed to generate wasm layout (More details are available in diagnostics mode or using the MSBuild /bl switch)

Thanks for the report. This is expected and was fixed with .NET 9.

Ok good to know.

I ended up having to update all my project dependencies from .Net Framework 4.7 to .Net Standard 2.0 as well.

It's still failing, but with a different error for WASM now.

Here are the current errors:

The RuntimeIdentifier platform 'maccatalyst-arm64' and the PlatformTarget 'x64' must be compatible.
The RuntimeIdentifier platform 'browser-wasm' and the PlatformTarget 'x64' must be compatible.

This is a not an error we're seen already. If you're publishing, make sure to use the commands from the documentation.
