VSS Provider and .NET

Hello,

I am trying to write my own implementation for vss provider. I took the sample code and and tried to modify it, but no matter how much I tried I can't integrate my .NET code into the provider:

1. Write a separate C# COM+ dll and access it from a provider compiled as a native code - Fail.

2. Write a mixed managed/unmanaged C++ to access my .NET code from the provider - Fail.

3. Write my C# implementation to the provider - Fail (as expected).

Any thought? I know Microsoft require the provider to be compiled as Native code. Does it mean that the only way to integrate my .NET code it to use a different process and communicate it via TCP for instance? 

Any help would be appreciated!!

Thanks :)
