Namespace / Class Qualifier

Question

I have a solution with several projects. One of them is Contexts (where the default namespace is XYZ), and another is BackOffice (where the default namespace is XYZ.BackOffice). BackOffice has a reference to Contexts.

I created a new class (Foo) in Contexts and I specified that Foo's namespace is XYZ. I then wrote some code in BackOffice that used Foo. I DID NOT QUALIFY Foo when I used it, nor did I add a using directive, and the build failed, as I expected. I then changed all Foo to XYZ.Foo and did another build. This time it was successful. I then removed the XYZ's that I had just added, and the build is STILL successful.

How is it now "remembering" the namespace? I did a clean and rebuild; no change. I dropped Foo from Contexts and re-add it; VS2008's automatic error checking showed the errors I expected, but then the next build was still successful.

This only bothers me because I fear that, although I get a successful build, when my teammates check out my code, they may not.

You must have a namespace qualifier somewhere. It may have a using somewhere that didn't get removed. Close your project and reopen. Sometimes there is a cached version of VS projects that probably is not getting updated in your case. Not sure what else to look for.
