Vs 2016 updating intellisense
So when I closed and reopened my solution the following day, the file wasn't in the project scope.
Adding the existing item to the project scope fixed it for me.
Both seem to stop working completely at the same time.
The only solution that I have tried is to reset all my settings, close out of Visual Studio completely and reopen the project again.
Here's some KBD shortcuts to try to reboot it, but don't know if they work. I had the same issue, it turned out to be that nuget packages were not automatically downloaded for a solution i downloaded from the repository freshly, thus intellisense was not available since none of the required packages to show the right suggestions were available.
Solution 2 Now "Restart the Visual Studio" and Try Again (mostly works).
Solution 3 Just delete the folder "Reflected Schemas".
Here, location depends on Visual Studio Version %App Data%\Microsoft\Visual Studio.0\Reflected Schemas -For VS 13 Solution 4 Next, reset the Settings from the following location.
