C# – Can not find System.Windows Assembly


This is the error we get:

Error 1 The type 'System.Windows.Point' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Windows, Version=, Culture=neutral, PublicKeyToken=7cec85d7bea7798e'. C:\PacMan\PacMan\PacMan\PacManTests\UnitTest1.cs 65 13 PacManTests

We get this error in our unit test project which cant find the System.Windows Assembly but our main project can find the assembly and run it fine.

Does anyone have any input or advice on where or how we can reference System.Windows to fix this problem?

Best Solution

In my case there was no System.Windows reference available to pick up.
I had to include a reference to WindowsBase
