ICorDebug Interface

Provides methods that allow developers to debug applications in the common language runtime (CLR) environment.


Mixed-mode (managed and native code) debugging is not supported on Windows 95, Windows 98, or Windows ME, or on non-x86 platforms (such as IA64 and AMD64).



ICorDebug::CanLaunchOrAttach Method

Determines whether launching a new process or attaching to the given process is possible within the context of the current machine and runtime configuration.

ICorDebug::CreateProcess Method

Launches a process and its primary thread under the control of the debugger.

ICorDebug::DebugActiveProcess Method

Attaches the debugger to an existing process.

ICorDebug::EnumerateProcesses Method

Gets an enumerator for the processes that are being debugged.

ICorDebug::GetProcess Method

Returns the ICorDebugProcess object with the given process ID.

ICorDebug::Initialize Method

Initializes the ICorDebug object.

ICorDebug::SetManagedHandler Method

Specifies the event handler object for managed events.

ICorDebug::SetUnmanagedHandler Method

Specifies the event handler object for unmanaged events.

ICorDebug::Terminate Method

Terminates the ICorDebug object.

ICorDebug represents an event processing loop for a debugger process. The debugger must wait for the ICorDebugManagedCallback::ExitProcess callback from all processes being debugged before releasing this interface.

The ICorDebug object is the initial object to control all further managed debugging. In the .NET Framework versions 1.0 and 1.1, this object was a CoClass object created from COM. In the .NET Framework version 2.0, this object is no longer a CoClass object. It must be created by the CreateDebuggingInterfaceFromVersion function, which is more version-aware. This new creation function enables clients to get a specific implementation of ICorDebug, which also emulates a specific version of the debugging API.


This interface does not support being called remotely, either cross-machine or cross-process.
