Visual Studio C# IntelliSense not automatically displaying

Question

Just recently, my Visual Studio 2010 stopped displaying IntelliSense suggestions automatically while I am typing. I can still press ctrl+space to get it to work, but it doe

Answer 1

Sometimes i've found Intellisense to be slow. Hit the . and wait for a minute and see if it appears after a delay. If so, then I believe there may be a cache that can be deleted to get it to rescan.

Answer 2

• Closed all my VS windows
• Started the Visual Studio Installer and clicked 'Modify'.
• Under 'Individual components' > 'Code Tools' > Deselected NuGet package manager and re-selected it.
• After modifying and restarting VS, IntelliSense was working correctly again.

Answer 3

I have found that at times even verifying the settings under Options --> Statement Completion (the answer above) doesn't work. In this case, saving and restarting Visual Studio will re-enable Intellisense.

Finally, this link has a list of other ways to troubleshoot Intellisense, broken down by language (for more specific errors).

Answer 4

At the bottommost right look at the blue line where Ln, Col, Spaces, UTF, CRLF,..... here the language is specified. Check that your language and the language specified there are the same. In my case, it was Django Python while I was trying to use HTML.

Answer 5

Deleted the .suo file in solution folder to solve the problem.

Answer 6

I simply closed all pages of visual studio and reopened ..it worked.
