I'm still hitting this in Microsoft.NET.Sdk.IL: 5.0.0-rc.1.20411.1, SDK: 5.0.100-preview.7.20356.2/5.0.100-preview.8.20359.7

C:\Development\winforms\.dotnet\sdk\5.0.100-preview.8.20359.7\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.ILLink.targets(99,5): error MSB6006: "dotnet.exe" exited with code 1. [C:\Development\winforms\src\System.Windows.Forms\src\System.Windows.Forms.csproj]

How/where do I get the fixed version?

@RussKie Do you still see the failure? I tried something similar with 5.0.100-rc.1.20453.7 and it worked.
If you still see a failure, could you please paste the exact error and what did you try?
