Remarks
The CLR calls a method in the ICorProfilerCallback (or ICorProfilerCallback2) interface to notify the profiler when an event, to which the profiler has subscribed, occurs. This is the primary callback interface through which the CLR communicates with the code profiler.
A code profiler must implement the methods of the ICorProfilerCallback interface. For the .NET Framework version 2.0 or later, the profiler must also implement the ICorProfilerCallback2 methods. Each method implementation must return an HRESULT that has a value of S_OK on success or E_FAIL on failure. Currently, the CLR ignores the HRESULT that is returned by each callback except ICorProfilerCallback::ObjectReferences.
In the Microsoft Windows registry, a code profiler must register its Component Object Model (COM) object that implements the ICorProfilerCallback and ICorProfilerCallback2 interfaces. A code profiler subscribes to the events for which it wants to receive notification by calling ICorProfilerInfo::SetEventMask. This is usually done in the profiler's implementation of ICorProfilerCallback::Initialize. The profiler is then able to receive notification from the runtime when an event is about to occur or has just occurred in an executing runtime process.
Note
The profiler registers a single COM object. If the profiler is targeting the .NET Framework version 1.0 or 1.1, that COM object needs to implement only the methods of ICorProfilerCallback. If it is targeting .NET Framework version 2.0 or later, the COM object must also implement the methods of ICorProfilerCallback2.
