I had a similar problem with a simple Web API project in Visual Studio 2015. I solved the problem, after reading that the easy fix was to set the Startup Project to the correct project. Since I had another Web API project in the same solution, I guessed that the project I was debugging was mixing up which index.html to debug, so I renamed that current one to index2.html. Then setting the Project properties Web tab to Specific Page and the page text: "index2.html" solved the problem.
