Can System.IO.MemoryMappedFiles.dll be used in VS 2008

This will not help you.

If this DLL is included with the .NET 4.0 redistributable, then you should have it installed already, and if you don't, you need to re-download and re-install the redistributable from Microsoft's website. This will allow you to run an application that was written and compiled for .NET 4.0.

If it is not included with the .NET 4.0 redistributable, then you will be unable to use it. Visual Studio 2010 is required to create .NET 4.0 applications; you can't use VS 2008 no matter what DLLs you may have.

In general, having people send you a DLL file is an extremely bad idea. And remember that software piracy is also an extremely bad idea (and illegal!). You need to purchase a copy of Visual Studio 2010 if you want to develop .NET 4.0 applications, or use the free Express edition, obtainable here.

You need VS 2010 to build .NET 4.0 applications

You cannot use .Net 4.0 assemblies in earlier versions of the runtime.
