System.Composition namespaces
System.Composition and its child namespaces (System.Composition.Convention, System.Composition.Hosting, and System.Composition.Hosting.Core) contain types for developing extensible applications.
This topic displays the types in the System.Composition namespaces that can be installed and used to create Windows Store apps.
To install the following namespaces, open your project in Visual Studio 2012, choose Manage NuGet Packages from the Project menu, and search online for the Microsoft.Composition package.
