Is “windowsbase.dll” part of any of the version of .net framework?

Hi,
Is “windowsbase.dll” part of any of the version of .net framework? I have googled it lot but unable to find proper answer, can anyone please tell me about that.

Thanks,
Mushq

I googled it, and seemed to find the answer, strange...

Anyways, it seems as if the Windowsbase.dll forms part of the .NET Framework 3.0 - well, it gets installed with it.
Also, if you install the Visual Studio 2005 extensions for .NET Framework 3.0 (Windows Workflow Foundation) you'd be able to utilise it.

This dll is mainly used to host the System.IO.Packaging Api

I hope my info was useful.

Thanks. :)

This dll hosts more than packaging and is used quite a bit in Windows Presentation Foundation.

Open the dll in Reflector to see what all it hosts.
