Develop Office Client Applications using Visual Studio
One of our loyal blog readers asked if "VSTO officially supports targeting the Client Profile? I did a quick check and it seems to be working fine but it is good if we explicitly mention whether it is supported." The answer is yes. Starting in Visual Studio 2008 Service Pack 1 (SP1), you can develop 2007 Microsoft Office solutions with .NET Framework version 3.5 or .NET Framework Client Profile. The .NET Framework Client Profile is a subset of the full .NET Framework 3.5 that has a size of 25-30 MB. For more information about the .NET Framework Client Profile, see .NET Framework Client Profile.
You can read more about how to target the Client Profile in the localized documentation article "How to: Change the Target .NET Framework"
If you build a solution with the Client Profile, then please let us know by commenting on this page. Does the performance suite your needs? How was the experience?

How about Office 2003? Is the client profile officially supported with an Office 2003 project?
