I'm creating a web part in Visual Studio 2008 that involves using the Open XML SDK 2.0. I'm getting an error saying I need to add a reference to the WindowsBase assembly.
However, I can only add this reference if I set the Target Framework for my web part project to be .NET Framework 3.5. If it is .NET Framework 2.0, the reference for WindowsBase is greyed out in the Add Reference window.
Will it cause me problems when I come to deploy the web part if it is targeted to .NET 3.5?
