I work with .NET by day, but have few .NET contacts in Second Life. There is a .NET developers group here on Microsoft Island.
They have a web page here at sldnug.net
From the web page:
To join up message Strawberry Fride or G2 Proto on the web or
in world by messaging them or search under Groups for ".Net Developers". Finally
search for Microsoft Island or click here for a SLURL or Second Life link to our island.
