HTTP Error 500.19 with ASP.NET 5 after moving a project to a new folder
• blog
If you move your ASP.NET 5 project to a new folder and run it, you might suddenly find yourself with a 500.19 error whilst IIS attempts to read your web.config. What I noticed was that the folder that IIS was looking in for my web.config was the old folder:
To resolve this, just restart Visual Studio even if you’ve only just opened Visual Studio fresh anyway. Don’t waste time fiddling around with a perfectly fine web.config.
I guess it is a teething problem with the latest version of IIS Express.
