Brett,
That sounds like something that the WmDotNet package will do when it is released later this quarter. Maybe someone from WM could post a description of its capabilities here.
Further down the road (early next year?), the new webMethods Fabric product will offer native .NET support. This would enable webMethods services that “join” the Fabric to invoke .NET services that have joined the Fabric as if they were local IS services. I believe the reverse would also be true. Fabric will also provide transparent failover between “WSDL-equivalent” services written in IS, java or .NET.
Most of Fabric is written in Java, but I understand that the .NET stuff will be written in C#.
HTH,
Mark
