There are at least 2 tools which I know of to browse and view source code between C# and VB.NET.
This should really be in every .NET developer’s set of useful tools. Reflector allows you to “reflect” and view raw .NET source code of any assemblies/applications written in .NET
This app helps if you have some .NET code you just want to quickly convert between C# and VB.NET. Copy, paste and convert!
Let me know if you find this useful or if you know any other similar tools.
