IIS express failed to start

IS Express cannot start

  1. .vs\config\applicationhost.config
  2. open. In csproject, change to False

method 1
use notepad or some other text editor, open the project. Csproj file, locate, clear all the IIS configuration, attributes, save to True, re-open the project with VS2015, then Ctrl+F5, success!
principle is to have VS2015 reset the boot configuration.
I tried this one, I guess it was an anomaly for different reasons, so it didn’t work

method two

delete the.vs folder in the code root and reopen it.
