I was getting very frustrating why these two new folders  always getting created every time when I compile the solution. Search through the project, nothing make the code generate the folders. Think Think Think, Google,  Google and Google.

Ok, it was because of i enabled the “Assembly Binding Log Viewer” when I debugged the DLL in a project few months ago. Use this to trigger the Assembly Viewer, what i need to do is just get the “Log disabled” checked and restart my machine – Problem solved.
