Disable Visual Studio 2017 Chrome Debugging

Visual Studio 2017 comes bundled with a version of Chrome which integrates with the VS debugging tools. It’s enabled by default and can be quite useful. However as it’s not the same version of Chrome you may have installed on your machine, it doesn’t give access to your bookmarks, browser extensions etc.

This feature can be disabled:

1. Go to Tools > Options.
2. Select Debugging then General.
3. Uncheck Enable JavaScript debugging for ASP.NET (Chrome and IE).

Next time you run your web application Visual Studio will use whichever version of Chrome/IE you have installed.

IIS Express Configuration File

The configuration file is called applicationhost.config It’s stored here:

My Documents > IIS Express > config

usually (not always) one of these paths will work

%userprofile%\documents\iisexpress\config\applicationhost.config
%userprofile%\my documents\iisexpress\config\applicationhost.config

Update for VS2015

If you’re using visual studio 2015 look here:
$(solutionDir)\.vs\config\applicationhost.config
