The requested and missing PDB file is a so-called program database used for debugging:

https://en.wikipedia.org/wiki/Program_database

It is not needed by your add-in, only for debugging AddInManagerUI.dll, which you should not be doing.

I have never seen or heard of this message before, so I would assume that you are doing something unusual.

I would suggest restarting from scratch with a clean slate, tabula rasa, and following a step-by-step tutorial exactly; the message should not appear.

that look like you try to debug your application, and try enter a dll not loaded in maping. There is a option in visual studio to not go into a dll that are not yours, I thing in bottom of this prompt is a hint how to turn it off.
