Regions for your existing VSTO Outlook projects
This solution effectively allows you to continue designing your Outlook solutions using Visual Studio Tools for Office. In other words, even if you have an Outlook Add-in project developed with VSTO, you can install Add-in Express Regions and immediately start taking advantage of powerful Advanced Outlook View and Form Regions technology.
Outlook view and form regions - key features
Advanced Regions provide developers several unique advantages over the traditional Outlook Form Regions available in VSTO projects:
Add-in Express helps Outlook developers write their code faster and better - one of our core philosophies. As such, Add-in Express Regions prominently features wizards for quickly creating your regions, associating them with Outlook windows and binding the regions to certain Outlook context.
