[RESOLVED] Directly call the classes in the .NET base lib (mscorlib.dll) in VB6

I often need to test some C#/VB.NET code in VB6. I'd like to know whether there is a way to directly call some classes in the .NET basic library (for example: mscorlib.dll or System.Runtime.dll) in VB6, such as Array, String, Encoding, Marshal, etc.

In addition, can we use the open source and cross-platform .NET-Core framework in VB6? Thanks.
