Scenario:  I have a test that needs a file deployed inside a folder (e.g. - DeploymentItems\ControlsMetaData.xml) You can use the DeploymentItem attribute with the 2 parameters overload and specify the directory (folder) you would like the test file to be deployed in.

Why the error? My WPF application UIXStandards has reference to a class library Controls which in turn has a reference to the Smt.Windows.Controls library. In Visual Studio when I add reference to Controls library from my UIXStandards   application, Visual Studio does not copy any references needed for the Controls library (e.g . ) Smt.Windows.Controls to UIXStandards application. Solution: To solve the problem, within Visual Studio when you refer to a class library ( Controls ) also add references its dependencies ( Smt.Windows.Controls ).
