I am having a problem in building my solution in VS2008. Normally, it compiles fine in the environment. Sometimes, it fails with:
/xxx_WEB/secure/CMSManagedT
I had this problem but none of the suggestions worked for me, mine may be a unique case, but just in case other people encounter the same problem:
Mine seemingly had nothing to do with Circular References and was in fact due to my build output. After a while of getting nowhere I placed a breakpoint on the control that couldn't be loaded and got a notification telling me that it would not be hit.
Changing both the project properties and solution configuration settings to build for Any CPU rectified the problem.
