Add-in Express for Internet Explorer is the only all-in-one framework that offers you a simple and quick way to customize Microsoft Internet Explorer with your own browser extensions. It completely supports the Internet Explorer Extensibility API and provides a coherent set of .net components, visual designers and deployment tools that make your IE add-on development and deployment very comfortable.

You write applied code only

Add-in Express is based entirely on the Rapid Application Development approach and empowers you to develop professional extensions for Internet Explorer with a couple of clicks. Add-in Express is written in C#, its programming model and run-time code are based on the Internet Explorer SDK and thus far provide the most effective way to extend the IE GUI, access Internet Explorer objects and handle their events.

Written in C#, optimized for IE 7 multi-threaded and IE 8 "multi-processed" architecture, and speeded up for IE 9, IE 10 and IE 11 load time requirements, Add-in Express wraps the Internet Explorer Extensibility API with a strong programming model and an elegant solution design. Now you can simply use IE-specific modules and components instead of digging through technical articles on the web. Just run the Add-in Express IE solution wizard, create your project, tune the deployment scenario and start your work - do coding. Forget about COM-interfaces, registry, jаvascript, IE threads and processes - merely concentrate on your own applied code!

Internet Explorer extensibility
Based on the Internet Explorer Extensibility, Add-in Express provides you with an integrated solution that allows adding your custom menu items, toolbar buttons, context menus, toolbars, side-bars and keyboard shortcuts to the Internet Explorer GUI.

Integrated solution in focus
Add-in Express integrates all Internet Explorer Extensibility features in one solution with a strong architecture and a lucid interaction model with Internet Explorer objects. You needn't follow the IE SDK way with separate ActiveX-es, script files and registry keys.

Visual designers
Add-in Express provides a component-centric model for programming IE add-ons. 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 IE plug-ins are script-enabled.

Version-neutrality
Add-in Express includes a version-neutral Internet Explorer interop assemblies based on the IE 6 type library. With these assemblies you make your add-ons compatible with the most popular Internet Explorer versions, from IE6 through IE11. One code, one project, one solution, one deployment package for all IE versions.

32 and 64 bits in one project
Add-in Express delivers its own 32-bit and 64-bit add-on loaders, automatically includes them in add-on setup projects and registers the loaders for both Internet Explorer versions, 32- and 64-bit. The loaders run your add-ons and isolate them in their own app domains. All this makes your add-ons x86 and x64-compatible, secure and isolated.

Deployment experience
Deployment is the premium feature of all Add-in Express projects. Each of your Add-in Express based plug-ins is msi-based and web-enabled. Just build your IE extension and its setup project and publish the resulting MSI to your deployment server.

Deep integration with MS Office add-ins
Add-in Express adds a special template to MS Office add-in projects based on Add-in Express for Microsoft .NET. It enables you to create Office add-ins and Internet Explorer add-ons with the common code base in the framework of one project.

True RAD - you write applied code only
Add-in Express is completely based on the True RAD paradigm and reduces the time you spend on COM interfaces, IE-related registry entries and IE add-on deployment. You write applied code only, Add-in Express implements everything else.
