Error CS0246 When Adding Namespace to Web.config - asp.net

Question

I have created a web project that acts as a link between a (ASP).NET web application and a web-based ERP solution. There are four of these web sites, all using the same .NET web application to run the web store. I have successfully applied the project to one site and now I'm trying to apply it to the others. However, when setting it up on the second site, I keep getting the CS0246 error. I have added the DLL file to the BIN folder and I added the namespace and web reference information to the Web.config file, just like in the first site. For the life of me I can't figure out why it keeps causing a server error, though. If I remove the namespace reference and the DLL file the error goes away. Here is what the Web.config file currently looks like:

I've been wracking my brain over this for a while now and would appreciate any additional insight as to what I'm overlooking here.

Answer 1

Ok, I figured out what was wrong. Basically, I didn't have complete information on the remote server. The one site I successfully set this up on was running .NET 4.0, but these other sites are on servers thatr only have .NET 3.5. Since the project was targeting .NET 4.0, I retargeted to 3.5 and everything started working. It just took a while to finally get this information.
