I encounter more and more vb.net because Microsoft uses it as their default "scripting" language for products like SQL Reporting Services. And for that, it actually seems to make sense as a language. In small sniplets it works better than C#.

But honestly Microsoft missed a huge opportunity by not simply making classic VB6 code run under the CLR. In entirely defeats the point of having a common language runtime if every language has to look exactly the same. It wouldn't have been an insurmountable project and would have driven higher the adoption of proper .NET.
