  1. First of all (if it's needed) Open your project in Visual Studio 2012 or later, choose Manage NuGet Packages from the Project menu, and search online for the Microsoft.Composition package.

  2. Right-click on your Project and select "Add Reference". Find System.ComponentModel in the Framework list and add it or the applicable sub assembly.

Thats's all I did when I faced this problem.
