I used a tool to convert NB_Store (open source ecommerce module) from VB.NET to C#. I placed a link in their discussion forum but a moderator removed it because he said the hosting page has popups. Actually one popup and if you use a popup blocker you notice it).  I didn't agree with their action and I have voiced my opinion in the same thread there. 

The link is at the bottom. If you're skeptical about  malware, safety or whatever,  like the NB_Store moderators are, then use a browser with a sandbox, a VM or whatever. It's just a zip file with converted code. They said they will release it once they verify it. Dunno know how long it will take and I am not going to wait.  I am not planning to spend any more time looking for another free upload site. You can do this if you want.  I am posting it here so that it gets more exposure as well. 

It doesn't compile because it needs the proper assembly references, just like the VB version and I haven't tested it. I converted it because I hate looking at VB.NET code!!
