Getting “type or namespace name could not be found” but everything seems ok?

Question

I\'m getting a:

type or namespace name could not be found

error for a C# WPF app in VS2010. This area of code was compiling fine

Answer 1

In my case, adding the dll as a reference gave the type or namespace name could not be found error. However, copying and pasting the dll file directly in bin folder resolved the error.

No idea why this worked.
