I've been working on a new WCF application for the past 6 months. I had originally proposed C# but VB.Net prevailed, because that was a standard for my particular dev shop. Interestingly, this policy changed in the last couple of weeks, so I immediately searched for a decent code conversion tool. I chose Telerik's based on a Hanselman blog. My code base consisted of multiple projects in a single solution. I zipped up each project into its own zip file and uploaded everything at once into Telerik's tool. The result was that 8 hours later I have a fully converted code base in C#. There was definately some manual fixes required after using the tool but 8 hours of tweaks on 6 months of coding is really nothing. So I just wanted to say thanks for this great free tool that you've provided.
