I wanted to add that Measurement Studio 8.0 will work in Visual Studio 2005. However, only C# and VB .NET are supported, not C++. Plus you do not get the full integration that you would normally get with Visual Studio 2003. This includes a Menu item for Measurement Studio, the DAQ Assistant, and wizards for developing Measurement Studio applications. For more information please take a look at the following articles.

Let me know if you have any questions.
Thanks,
