	Interface	Description
	Breakpoint3	Contains the properties and methods that are used to programmatically control a breakpoint. To use Debugger4, you must add a reference to EnvDTE90a.dll. For native development, you must add a reference to dte90a.tlb.
	Debugger4	Debugger4 is used to interrogate and manipulate the state of the debugger and the program being debugged. Debugger4 supersedes the Debugger3 interfaces.
	Process4	The Process4 object is used to examine and manipulate processes. The Process4 object supersedes the Process3, Process2, and Process objects. To use Debugger4, you must add a reference to EnvDTE90a.dll. For native development, you must add a reference to dte90a.tlb.
	StackFrame2	The StackFrame2 object is used to examine and control stack frames. A stack frame is essentially the same as a function call. To use Debugger4, you must add a reference to EnvDTE90a.dll. For native development, you must add a reference to dte90a.tlb.
