>I would guess this is not a Web Application Project since if I remember correctly the App_Code folder is not allowed for that type project. This would mean his project does not compile into a single dll, but rather a bunch of random named dll's. I am not actually sure if the code in the App_Code folder gets compiled with a build or not. Best solution is to use Web Application Projects, and compile all of it into a dll.

Yes, the project type might be adjusted accordingly to benefit from that.

Thanks for mentioning it.
