Core Editor

The Visual Studio core editor is a set of several components that let you modify and query textual information. Because you can customize the existing core editor, you do not have to design and implement a full-fledged editor or edit control of your own in your VSPackage implementation. The following are the primary components of the core editor:

• Text buffer

• Text view

• Code window

• Text marker

• Text manager

• Language service
