NETMF, Missing assemblies System.Net and System.Net.Sockets?

Where do I download missing assemblies System.Net and System.Net.Socket for NETFM? They are missing when I try to add them using them Add References!

I have installed "Microsoft .NET Micro Framework 4.3 (QFE2) " and “GHI Electronics NETMF SDK 2016 R1 Pre-Release 1” on a VS 2013.
Thanks

Both are included in the System assembly - take a look with object browser.

I don’t see the System.Net and System.Net.Socket in the object browser. See the image posted.
Thanks.

@ bghavami - The screen you displayed is NOT the object browser. But, the reference browser does contain an entry for System, which is the DLL Sprigo told you to include.

That did the job.
:dance:

Thanks.
