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)

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

release-20250204.zip

Uno.Sdk: 5.5.49

.net 8 still.

Building on Windows with VS 2022, version 17.12.2

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

I've tried using the commands from the docs, as well as building in VS. I still get the same error for both mac and wasm. I was able to resolve the build issue by putting this in my .csproj file:

    <PropertyGroup Condition="'$(TargetFramework)' == 'net9.0-browserwasm' OR '$(TargetFramework)' == 'net9.0-maccatalyst'">
        <PlatformTarget>AnyCPU</PlatformTarget>
    </PropertyGroup>

Without that snippet, it throws the error building for Release and Debug. With it, things build but then we have issues trying to debug (WASM says it couldn't listen on port 5000). I'm not sure if the two issues are related at all, or if we'd have the debug issue even if we resolved the build issue without the snippet above.

Here's a binlog of the error:

This error is expected with the configuration being set. It seems that the "Platform" property is set when is should not be.

Can you provide the command line you're using?

I just was building using VS 2022 17.12.2.

I get the same error message when I clean the project and when I build using the CLI with the command: dotnet build /bl WereAllRelated.Uno.csproj.

Here's a binlog from building from the CLI:

I see, you're using the workaround for #18552, which is causing this issue. This workaround is only useful when building for winappsdk, for the other targets it will break the build.

Make sure to set the PropertyGroup around the workaround with a Condition=" '$(TargetFramework)' == 'net9.0-windows10.0.26100' ".
