xcad does not compile (.NET5.0) due to RegAsm.exe

dotnet.exe build:

I have not yet ported this to NET 5. It is not using registry free COM, but RegAsm should not be called. RegSvr32 is used for NET Core and .NET 5. I believe the issue is targets file which is missing the case for net5 and fallback on NetFramework while should fallback on NetCore.

As a quick workaround, you can disable the automatic registration with false property and manually call regsvr32, but at this stage, I would recommend writing SW add-ins in .NET Framework until SOLIDWORKS officially supports .NET5/.NET Core, there were few issues reported in .NET Core when using EF, there might be more which we are not aware of. I you are writing stand-alone then it is OK to use .NET Core/NET5.

I figure out how to manually registry COM .dll

dotnet build
dotnet publish -r win-x64 -c Debug
regsvr32.exe  .\bin\Debug\net5.0-windows\solid.abastran.tools.comhost.dll
