Assemblies in the Visual Studio Tools for Office Runtime

When you create an Office project, Visual Studio automatically adds references to the Visual Studio Tools for Office runtime assemblies that are used for the project type and the target .NET Framework of the project. There are different assemblies in the Office extensions for the .NET Framework 3.5, .NET Framework 4, and .NET Framework 4.5. For more information about the Office extensions, see Visual Studio Tools for Office Runtime Overview.

The following table lists the assemblies that are included in Office extensions for the .NET Framework 4 and the .NET Framework 4.5. For documentation about the namespaces and types in these assemblies, see Managed Reference (Office Development in Visual Studio).
