[SOLVED] Visual studio won't debug into referenced DLL (from same solution)

Visual studio won't debug into referenced DLL (from same solution)

I have a Visual studio 2008 solution, with 2 projects. A DLL, A, and a Web application, B.

B has a project reference to A, and A.dll and A.pdb are being copied to B's bin/ directory.

Everything is set to compile in debug mode.

I can run the cassini webserver and debug web application B fine, but when I come to call a method in A.dll, pressing F11 to step into it does not step into it, it steps over it. I want to step into it.

Any ideas why I might not be able to step into the source code of A?

Edit: Additional Info

I do not have 'just my code' checked.

I can set a breakpoint in the DLL, and it shows as a red circle (not a hollow one), but it is never hit.

Hmmm... I just altered the code in the DLL which is being called to start with

throw new Exception("Hello");

And I'm not getting an exception. That's pretty suspicious...

Solution

Aha!

The method in B I was calling returned IEnumerator<SomeObject>. It was an iterator block with yield keywords and so was not being executed (as I hadn't written the consumer yet).
