After Visual Basic Power Packs 3.0 was released to the web, we got a lot of questions and feedbacks from Visual Basic Power Packs MSDN forum.   So when Visual Studio 2008 Service Pack 1 was about to release, we decided to ship  Visual Basic Power Packs with all the bug fixes with this service pack.  While you can still use the web release of the VB Power Packs, it is recommend that you use the version included with Visual Studio 2008 SP1.

If you had installed Visual Basic Power Packs 3.0, you would end up with two tabs in the toolbox, one labeled “Visual Basic PowerPacks” (released with Visual Studio) and “Visual Basic PowerPacks 3.0” (web release).

To differentiate these two versions, the assembly name is changed to Microsoft.VisualBasic.PowerPacks.VS.dll.   If you have an existing application that is using Visual basic Power Packs 3.0 or lower version, you can upgrade to the new VB Power Packs by deleting the reference to Microsoft.VisualBasic.PowerPacks.dll and add reference to Microsoft.VisualBasic.PowerPacks.VS.dll.

We also provided a new bootstrapper package for the new VB Power Packs.   So if you were using Windows installer or ClickOnce to deploy your application, you need to also change the prerequisites of your setup project to point to the new bootstrapper package.
