Extending the Editor

项目
02/28/2011

You can extend most features of the Visual Studio code editor by using the Managed Extensibility Framework (MEF) instead of implementing a VSPackage. For example, if the editor feature you want to extend is syntax coloring, you can write a MEF component part that defines the classifications for which you want different coloring and how you want them handled. The editor also supports multiple extensions of the same feature.

The editor presentation layer is based the Windows Presentation Framework (WPF). WPF provides a graphics library for flexible text formatting, and also provides visualizations such as graphics and animations.

The Visual Studio SDK provides adapters known as shims to support VSPackages that were written for earlier versions. Nevertheless, if you have an existing VSPackage, we recommend that you update it to the new technology to obtain better performance and reliability.
