The type or namespace name 'Properties' could not be found

I was getting an error message when building my project that said "The type or namespace name 'Properties' could not be found".

This was because I had changed the default namespace in the properties for my project to make it "project.name" instead of "name". The class that did not build was already in the namespace "project.name".

The error message was on a line that said

"global::name.Properties.Resources...."

Changing this to

"global::project.name.Properties.Resources...."

seemed to fix the problem.
