What is NetFx in the Windows SDK?

Question

What is NetFx, in the context of the Windows SDK? What differentiates NetFx tools from the tools in the regular SDK bin directory?

I noticed that the version of sgen.exe in C:\Program Files\Microsoft SDKs\Windows\v7.0A\bin\ was built against .NET 2.0, but the version in C:\Program Files\Microsoft SDKs\Windows\v7.0A\bin\NETFX 4.0 Tools\ was built against .NET 4.0.

Update: After a little more searching I found hints that NetFx is the "new" name for WinFx, which was originally a branding intended to convey ".NET with some extra stuff".

Is this right?

NetFx is apparently just shorthand for "Microsoft .NET Framework."

I can see how this might be confusing. There are several references to NetFx in Google, including this company, and this open-source project.
