This is really frustrating. I've sent two projects two a coworker. One is a website and the other gets built into a DLL. On my computer I simply copy the DLL and PDB files into the bin folder of the website. I immediately have access to the intellisense and can step through the DLL code in debug mode.
My coworker copied the files to the same place on his computer, loaded the solutions for both projects, can build them fine, copied the dll into the website's bin folder, it runs fine, however no intellisense is available. On top of that, when he tries to step through the code, a file browser pops up asking him where it is. The class names and everything are rendered in Visual Studio as normal black text, and have no info on the mouseover.
We tried creating two new projects on his computer and adding the existing code to them, but VS still can't see the code for the other project. What I don't understand is that it runs perfectly. It has the pdb file, so what is wrong with it?
