If you're developing a Universal Windows app, your project automatically references all of the correct Windows SDK DLLs. If you are developing a .NET application, your project automatically references *mscorlib.dll*. Some .NET APIs are exposed in components that you have to add manually.

 An SDK is a collection of files that Visual Studio treats as a single component. In the **Extensions** tab, SDKs that apply to the project from which the Reference Manager dialog box was invoked are listed as single entries. When added to a project, all of the SDK content is consumed by Visual Studio such that the user doesn't need to take any further actions to leverage the SDK contents in IntelliSense, toolbox, designers, Object Browser, build, deployment, debugging, and packaging.
