Intellisense stop working
Steps to Reproduce:

My extensions:
Same Version and OS here also have the same issue. It seems to work after starting VSCode, but stops after a few mins. I have ESLint, jshint, and npm intellisense extensions in common with 50l3r
50l3r: Have you tried disabling all hinting extensions, and enabling them one by one to see if one of them are the cause?
It's also happening to me after i've updated. Intellisense works on start up, stops working after few seconds, to not come back working at all. I have just these two extensions bellow installed.
|Extension|Author|Version|
|---|---|---|
|vscode-codemetrics|kisstkondoros|1.7.2|
|Material-theme|zhuangtongfa|2.8.5|;
the same with me, visual studio on window died
Disabling the other linters and intellisense extensions didn't seem to help. When intellisense does die Ctrl+Space just shows "Loading..."
intellisense stopped working for me on script tags within html files
@quonic, @hiepxanh @pdgago Are you seeing the issue in html files only or any other languages too?
cc @mjbvz
Potentially the cause: https://github.com/zignd/HTML-CSS-Class-Completion/issues/58
Disabling the extension does make intellisense work again for me. Enabling it again makes it work for a few seconds, then seems to kill off the intellisense again.
@ramya-rao-a It seems to also happen in Powershell files.
For me the problem was caused by the polymer.polymer-ide plugin. I disabled it and it's working again. I was having problems with html files.
Closing this issue as the problem was caused by extensions.
Please log an issue in the repo for the extension that is causing this.
I'm having this same issue and i dont have that plugin installed....
Suggestions/Intellisense works for few seconds when VScode starts after that it stops working
@mahaveer0496 Do you see the issue in different languages or only 1?
I only use VScode for React, React-Native so I can only speak for Javascript :) @ramya-rao-a
I changed to the previous version ( 1.13.1 ) and everything is back to normal.
cc @mjbvz for auto-completion issues in javascript
@ramya-rao-a I'm seeing this issue while editing PowerShell scripts after VSCode has been up for a long period of time without restart (8+ hrs). It gives me "No suggestions." on built-in cmdlets
@TheIncorrigible1 Please log an issue in the repo for the Powershell extension that porvides the suggestions.
Just to log. @50l3r
For me Azure Extension Packextension was the culprit
I'm using C# and intellisense frequently stops working. F12 stops working. Sometimes if I restart it works. Today nothing works.
Found a fix. I opened project alone (not in workspace) and then VSCode performed a restore and then everything started to work again. Then I can switch back to workspace and it works fine again.
I can confirm the same behavior. It works when the app starts and then stops after few minutes. I am using 1.18.0.
@hamidmaddi Please share the type of file you are seeing the issue in. C#, js, powershell?
