Now you can develop enterprise-grade extensions for Internet Explorer 6 through 10, 32-bit and 64-bit, using VS 2012 and .NET Framework 4.5. Add-in Express fully complies with Visual Studio 2012 UI guidelines and extends the IDE with ready-to-use project templates, wizards and components that largely simplify the development of powerful and stable browser extensions.

In contrast to the IE SDK, which offers disembodied solutions based on ActiveX objects or scripts for commands, toolbars, explorer bars etc. Add-in Express integrates everything in one project with a lucid, easy-to-understand architecture and an interaction model with Internet Explorer. You needn't follow the IE SDK way with separate ActiveXs, script files and registry keys.

Add-in Express eliminates the necessity to realize each command as a separate COM object and register it in a separate registry key. It integrates all your commands in one collection (the Commands collection of the IE Module) with its visual designer. Add-in Express contains command events and registers all commands itself. So, you use visual designers and components for customizing the Internet Explorer menu, toolbars or side-bars, and for accessing Internet Explorer objects and their events. In addition, all your add-ons are script-enabled.

Each of your Add-in Express solutions is msi-based and web-enabled. Just build your IE extension and its setup project and publish the resulting msi to your deployment server.
