I am trying to debug an asp.net application using the CLR Debugger, but when i try to attach to the w3wp.exe process i get the following error...

Unable to attach to the process. The Debugger was unable to automatically select and appropriate type of code. Please manually specify the type(s) of code to which the debugger should attach.

How do i manually specify the type of code?

I am running Vista 64 bit / IIS7 i am running the debugger as an administrator

Has the application been compiled in DEBUG mode?

The appilication hasn't been written in Visual Studio, but a bespoke IDE based on VS for the product i'm developing, so unfortunatly i can't compile in debug mode

Other developers on server 2003 are able to debug without issue, so i assume the bespoke IDE complies in DEBUG mode. I think the problem is a vista/IIS 7 config issue?
