query about Frame maker 11

Hi All

This is regarding a query about Frame maker 11.

I have seen the in the FDK guide of FM 11 which states that  "To compile FDK clients for Windows, you must use Microsoft Visual Studio 2010."

So do we need a separate installation of  Microsoft Visual Studio 2010 in order to develop/compile  FDK clients apart from FM11 installation  or is its a part of FM11 software?

could you please any one can clarify on this .

Thank you .

Regards

Ramesh
