Ich bin mit dich, Mark Longmire. I am with you. Six years later and still no solution found. Here is the lay of the land...

Someone else's binary: a .dll provided by a 3RD party who intentionally did not want it debugged.

Our own code: C# running in VS in Debug mode so we can step through our own work.

What we do NOT want: to debug the .dll (that is absolutely NOT our need or care).

What we DO want: to leave the .dll as an UNdecompiled UNexamined UNdebugged black box, exactly as its original creator intended.

What we DO want: to debug our OWN C# code withOUT Captain Obvious (Microsoft Visual Studio Debug mode IDE) halting execution by declaring "Symbol file not loaded" or "No symbol file loaded for .dll" or "Binary was not built with debug information"

We will gladly shower praise on anyone who knows of a way to make VS IDE "Shut Up And Proceed Anyway" withOUT attempting to debug the black box .dll which does not want to be debugged.

Our forever admiration and thanks in advance, Johann
