Unable to start program at (aspnet core WebAp url) An operation is not legal in the current state.


  • This happens lot of times. (but sometimes not).

    It is an ASP.Net Core MVC app, executing Chrome.

    VS2017 Enterprise, V 15.7.2

    I found something similar occurs in the past with older vewrsions, like VS2013. Buit non of the "fixes" works.
