Russell Pooley has done some research into VB.NET to C# tools  (via Matthew Reynolds).  I always seem to find a lot of tools for converting from C# to VB.NET but seldom the reverse.  These tools are great for me because being a former Java guy, I find C# very easy to pick up and understand, but I have never written any code in VB.NET.   Now I can take code snippets I see in VB.NET and convert them (plus a little tweaking usually) and then I have it in C#!  (I know, it is all .NET, but C# is where I am most comfortable!)
