TAPI Service Provider With C#

Question

Hello,

I want to build a TAPI Service Provider (TSP) similair to the H323 TSP.  Basically I have developed  an assembly that provides call control functionality through a hosted VoIP switch.  I use this assembly in a desktop application, and have also built a COM wrapper so it can be incorporated into other people's application (provided it's written in either a .NET or COM-compliant language.) 

Now I want to build another "wrapper" around this assembly so that it can be consumed by any application that supports TAPI, such as Outlook, Goldmine etc.  I have learned that I need to use the TAPI Service Provider Interface (TSPI) in order to ensure the TAPI server can work with the TSP, but all examples and articles use C/C++.  Since my assembly is written in C# and I don't know C/C++, I'm wondering if I can use C# to create the TSP. 

Does anyone have any experience of doing this?  If so can you please help me to get started?

Thanks.
