Many companies, including mine, old have older systems written in VB kicking around. I fortunately don’t deal with them directly very often, but when I do, the Telerik code converter is a major help. Rather than spend time converting bits of code to or from VB and C#, just go to the URL, paste in the code and it will convert to and from the languages.
An added benefit is that it’s a simple website with two large text areas. You don’t need to download and install your thousandth tiny developer utility.
