I have no Idea of what is the issue, but creating a new solution and importing the existing projects into a new solution has solved all the issues regarding emulator and debugger an AgHost.

Answer 2

There was a post-VS2013 update for the Windows Phone 8.1 SDK, some odds that you don't have it installed since you did not need it before. The download location is here.

Getting error messages like "port is in use" when there's no obvious reason why it should be in use and seeing excessive download times is also a very strong selector for your installed anti-malware product getting in the way. No specific advice on how to configure it when we don't know what it might be. You definitely first want to try to temporarily disable it so you can identify it as the source of the problem.
