Which version of Add-In Express?

We currently have an ADX VSTO application (Outlook 2003 and Word 2003 addins) developed in VS2005 with the VSTO SE runtime.

Now looking at modernizing. If we develop an Outlook 2007 addin now, can it be expected to work with Outlook 2010?

Which version of ADX should we use? I can see the different features listed for ADX .Net and ADX VSTO, but I don't understand which ones should drive the decision. For example, when I wrote the current application, VSTO made loading and running the my addin simple, but the installer was rather difficult to write. I believe that has changed -- why would I not use VSTO now? What are the benefits of using ADX .Net?

Can you tell me what my upgrade path is, from starting from our current license? We are currently using version 3.2.2491.0, which is nearly 3 years old.

What do I need to do, to start working with the latest version?

At the moment I can't tell you anything on how an Office 2003/2007 add-in developed in VSTO 2005 SE would work in Office 2010. Most probably, it will work correctly. But note they've introduced shutdown changes in Outlook 2010, see http://msdn.microsoft.com/en-us/library/ee720183(office.14).aspx.

They simplified the deployment part in VS 2008 so that you can now deploy your Office 2007 add-in via ClickOnce only (In VS 2008, an Office 2003 add-in is developed using the same VSTO 2005 SE). Add-in Express for .NET allows installing via .MSI and ClickOnce. In addition, now we work on supporting web-based deployment for delivering MSI-based installers to the target PC.

To upgrade to the latest version please see Purchase | Upgrade to version 2009 in the main menu of the site.
