The IL Stub Diagnostic Tool enables real-time inspection of the contents of IL stubs.
One of the problems with the old 32 bit marshaling infrastructure was that it worked essentially as a black box that was very difficult to debug if something went wrong. The IL Stubs Diagnostic Tool provides a window into what used to be a black box and allows you to look into the very core of interop marshaling – the IL Stub itself.
IL stubs are dynamically generated on the fly by the CLR and handle the marshalling and invocation of the target method. The IL Stub Diagnostic tool was created to ease the interop debugging experience. It is a real-time monitor which shows the details of every IL stub generated by the CLR in a given process. For each stub, the tool currently displays its IL code as well as the signature of the managed/native methods.
Special thanks to Yifeng Fu for being one of the key developers of IL Stub Diagnostic tool during his internship at Microsoft.
