visual studio not updating html / javascript to server / browser

I also experienced this issue and turns out it was related to caching.

If using Chrome DevTools, you can simply disable cache by navigating to the Network Tab and ticking Disable Cache

This will only disable the cache when Dev Tools is open.

In Opera and Chrome (and possibly others), you can disable caching while in 'development mode'.

While in DevTools, the 2nd option in the Settings menu is

Disable cache (while DevTools is open)

Go to your web.config file and make a change in it.Its not matter what change you make.For example type a character and then delete it and build the project and run it again.I hope it works.

ctrl+shift+F5 will do the trick! Seems like browser cache is part of the problem :)
