• A probe function that is injected by the profiler may cause an unhandled exception if the miPreserveSig flag is not set.For additional information, click the article number below to view the article in the Microsoft Knowledge Base:

  310827 PRB: Probe Function Injected by Profiler May Cause Unhandled Exception

• The profiler may receive a just-in-time (JIT) compilation event but not a function enter event if the function is executed on context-bound objects.For additional information, click the article number below to view the article in the Microsoft Knowledge Base:

• A method whose ID is passed to an UnmangedToManagedTransition callback with the flag COR_PRF_TRANSITION_CALL may not be just-in-time compiled.For additional information, click the article number below to view the article in the Microsoft Knowledge Base:

  312222 PRB: Profiler Does Not Receive JIT-Compilation Notifications for Method with Reason COR_PRF_TRANSITION_RETURN

• A method whose ID is passed to a ManagedToUnmanagedTransition callback with the reason COR_PRF_TRANSITION_RETURN may be a "stub" function, and therefore the profiler will not receive just-in-time compilation and function enter/leave events for this method.For additional information, click the article number below to view the article in the Microsoft Knowledge Base:

  312220 Function Passed to UnmanagedToManagedTransition Callback Is Not JIT-Compiled

• The profiler may not receive transition-related notifications in some Interop scenarios. For example, no UnmanagedToManagedTransition will be received if CoCreateInstance results in a managed object.For additional information, click the article number below to view the article in the Microsoft Knowledge Base:

• The profiler may receive an AssemblyUnloadFinished notification before the AssemblyLoadFinished notification if the CLR aborts the loading of the assembly.For additional information, click the article number below to view the article in the Microsoft Knowledge Base:

• SetILInstrumentedCodeMap may cause an access violation if it is called from a JitCompilationStarted callback with the fJitStart flag set to "FALSE".For additional information, click the article number below to view the article in the Microsoft Knowledge Base:
