I'd the same issue on a WCF project on VS2017. When I debug, it gives errors like not able to get meta data, but it turns out the port was used by other process. I got some idea from here, and finally figure out where the port was kept. There are 2 places: 1. C:...to your solution folder....vs\config\applicationhost.config. Inside, you can find the site that you debug. Under , remove the that has port issue. 2. C:...to your project folder...\, you will see a file with ProjectName.csproj.user. Remove this file.

So, close the solution, remove the and the user file mentioned above, then reopen the solution, VS will find another suitable port for the site.
