The Catch

What’s the catch? The SharePoint development tools included in Visual Studio 2010 are exclusively for SharePoint 2010.  What can you use to accelerate your SharePoint 2007 development today? Check out WSPBuilder. WSPBuilder is an open-source tool and add-in for Visual Studio 2008 that not only automates a lot of the manual tasks of creating a SharePoint solution package (WSP file), but also comes with lots of Visual Studio templates for SharePoint artifacts, like web parts, features, content types, etc…. There’s a great WSPBuilder walkthrough by Tobias Zimmergren here.

Then. look at SharePoint Solution Installer. SharePoint Solution Installer will take any WSP package and wrap it in a very friendly wizard interface. Next, next, next, and the WSP you created using WSPBuilder is deployed to the entire SharePoint farm.
