I would consider not worrying about the tools, but really asking myself, why do you want to do this?
We have a project containing more than 500,000 lines of VB.NET, we need to convert to C#. Any suggestions based on experience, which tools to use? We are using Visual Studio 2008 and our goal is 3.5.
I agree with the comment. You have 500,000 lines of verified VB.NET code. Why would you waste any time to change it? No one says you can’t write all new components in C#.
