Solution 1

The "using directive" is your using mynamespace; piece of code. An "assembly reference" is a reference to an assembly[^].

In this case, you are probably missing an assembly reference. If your ConsoleApplication2 is in another project (but in the same solution), then:

Go to the Solution Explorer.
Right-click on "References" and choose "Add Reference".
In Visual Studio 2012/2013, choose "Solution", in VS 2010, choose "Projects".
Select the project that contains your ConsoleApplication2 namespace and click OK.

If the ConsoleApplication2 project is not in the same solution, then chooose "Browse" instead of "Solution" and choose the desired assembly from your file system.
