(Update 4/27/2015 Added Asp.net intellisense failure)
I was running the latest version of Visual Studio 2013 and ran into the intellisense not automatically popping up when I would type a period. Now I could hit CTRL-J (list members) and it would pop up the list which showed me that it worked and was not dead per se, but I still did not have it automatically popup after typing a period. I was also running Visual Studio 2012 on the same box and it did not have the same problem; intellisense popped the list up on the period. I thought, “This ends here” and researched it. Here is what made it auto pop for me:
- In quick launch type “Statement Completion” and choose the first one “Text Editor -> All Languages -> General” to be taken to the options page for all languages.
- On the general options page in the “Statement Completion” section override whatever is in the boxes “Auto list members” and “Parameter Information” and makes those checked. Such as shown here:
That brought back the auto popup for me in VS2013 and should for you as well. This fix should work with any version of Visual Studio 2008, 2010, 2012 and 2013.
Still having problems? Then see Using Intellisense on MSDN for other troubleshooting suggestions.
It has been reported that ASP.Net users are experiencing a different kind of intellisense failure. If it is web related intellisense look into installing Visual Studio Web tools. See
