Process with an ID #### is not running . // every tim

Answer 1

The following steps fix the problem for Visual Studio 2015 and Visual Studio 2017:

• Close VS.
• Navigate to the folder of the solution and delete the hidden .vs folder.
• Restart VS.
• Hit F5 and IIS Express should load as normal, allowing you to debug.

Note: Based on my experience and others in the comments, this problem seems to be caused by moving a project between workstations, environments, or versions of Visual Studio. There must be some environment specific information contained in the .vs folder.
