Currently the SDK includes recovery plan sample code that you can build on .NET. You can build C# .NET samples using Microsoft Visual C# 2008 Express or Microsoft Visual Studio 2008.
If you have a later version of Visual Studio, it might ask to convert the solution and project files before proceeding. An earlier version of this SDK supported Visual Studio 2005. Visual Studio 2003 was never supported because of performance issues (.NET took a long time to instantiate the VimService class).
