Tried the export but get the following error:

MInimal patch, only VL.Skia referenced and a Renderer[Graphics.Skia]:

Thanks for the report. The problem is that our software and the dotnet SDK have an overlap in the used libraries. So if any of them gets updated the C# compiler fails to load. This is now fixed by invoking it out of process to build the exported solution. Same will happen when referencing C# project from within a patch (that feature was also broken).
