SYMPTOMS

When the profiler receives an UnmanagedToManagedTransition notification with reason COR_PRF_TRANSITION_CALL, the functionId that is passed to the callback may correspond to a managed function that is not yet Just In Time (JIT)-compiled. Therefore, when you use this functionId in any ICorProfilerInfo methods to retrieve information about the corresponding managed function, you may experience failures.

CAUSE

This behavior can occur if the managed function is not available (it is not yet JIT-compiled).
