You are most likely running the program on a Windows XP machine.

Check the Platform section for a list of supported platforms for that class:

Some features in the .NET framework require specific libraries which are not available on all versions of Windows that support .NET.

Even if you have a compatible platform, the library might be a addon you need to enable through the Control Panel, or download from the Microsoft website.
