Overview

Concord is the code name of Visual Studio's new debug engine that originally shipped in Visual Studio 2012. The basic design of Concord is a collection of many modular, self-contained components working together to form the debug engine. Concord is extensible and new components can be added to enable debugging different languages, different runtimes, or to add new features to the debugger.

These components communicate through a special API. This API greatly simplifies the task of writing components and integrating them. Here are some features of the Concord API:

• Supports transparent managed/native marshalling enabling components to be written in either managed or native code.
• Handles the complexity of communication between the IDE process and the remote debugger process (msvsmon).
• The API itself is available as part of the Visual Studio SDK enabling anyone to write new components.
