Question

Answer 1

Solution:
1. Run VS as Administrator. Open your sln, Start debugging, stop and close the VS.
2. Again open the sln (without admin) file and start debugging.
It worked!

Problem:
- My VS2017 was running fine with debugging, until some other tool's installation corrupted it. Then I reinstalled it. When I started debugging/running site, it wasn't even opening first page of site. It was keep loading assemblies forever. I tried many things found on google. It didn't help.
- Finally I tried opening it with Admin and then regular. It solved my problem.
