Hi Jan,
I don't know whether you figured it out yourself in the meantime, but I have
had the same problem today and made it work. So I just wanted to share my
brilliance with you... :-)
Here you go:
clr.GetClrType(CalculatorService)
The clr object offers the "GetClrType" method which returns the type.
I used it in a different context though: XML (De-)Serialization. Worked very
well.
Let me know whether you had success...
