Debugger2 Interface 

The Debugger2 object is used to interrogate and manipulate the state of the debugger and the program being debugged. The Debugger2 object supersedes the Debugger object.

Namespace: EnvDTE80
Assembly: EnvDTE80 (in envdte80.dll)

[GuidAttribute("8B5E2BFD-4642-4EFE-8AF4-0B2DA9AAA23C")] 
public interface Debugger2 : Debugger
/** @attribute GuidAttribute("8B5E2BFD-4642-4EFE-8AF4-0B2DA9AAA23C") */ 
public interface Debugger2 extends Debugger
GuidAttribute("8B5E2BFD-4642-4EFE-8AF4-0B2DA9AAA23C") 
public interface Debugger2 extends Debugger

The debugger is available through the DTE2 object via its Debugger property, as shown in the example below. One debugger object is available for each instance of the development environment.

// The following C++ program can be run from the command line.
// It detects whether an instance of Visual Studio is currently 
// running,and if so, prints a message stating whether its debugger
// is actively debugging.

#include <stdio.h>
#import "dte.olb" raw_interfaces_only named_guids
