Unable to start debugging. The startup project could not be launched. VS2015

Question

I have started a new console project in VS2015. I only have this code :

using System.Collections.Generic;
using System.Linq;
using System.Text         


        

Answer 1

I had visual studio 2015 with an ASP.net MVC5 arcitectured with DDD (Domain Driven Design). The problem was the same since I just opened visual studio normally.

The problem was solved when I closed all instance visual studio and restarted as an adminstrator.
