A target framework moniker (TFM) is a standardized token format for specifying the target framework of a . NET app or library.

What does target framework mean?

A target framework is the particular version of the . NET Framework that your project is built to run on. Specification of a target framework is required because it enables compiler features and assembly references that are exclusive to that version of the framework.

How do I check my target framework?

To verify the change, on the menu bar, select Project > Properties to open your project Property Pages dialog box. In the dialog box, select the Configuration Properties > General property page. Verify that . NET Target Framework Version shows the new Framework version.
