Explain the full exception handling flow in CLR.

Expert C#
Quick Answer When an exception is thrown, the CLR unwinds the call stack frame by frame, searching for a matching catch handler. First-chance exceptions are raised before any handler runs (useful for debuggers). Finally and fault blocks always run during unwinding. Unhandled exceptions terminate the process.

Answer

Flow:

  • Throw triggers stack unwinding.
  • Search for handlers.
  • First-chance and second-chance exceptions.
  • finally, fault blocks executed.
  • Managed/unmanaged transitions handled by the runtime.
