问题
I think this is just happening to me, but every time I start my project in VS I have to do devenv.exe/resettsettings otherwise the intellisense doesn't work. Does anyone know any special reasons as to why?
回答1:
These options should be enabled:
Tools->Options->Text Editor->C#->General->Auto list members
Tools->Options->Text Editor->C#->General->Parameter information
Tools->Options->Text Editor->C#->Intellisense->Show completion list after a character is typed
If it doesn't work try this:
Tools->Import and export settings->Reset all settings

after many posts, I can solve this problem well:
Execute developer prompt command for visual studio 2012 --> gacutil /u Microsoft.VisualStudio.CSharp.Services.Language.Interop
solved the problem for me.

Close the current Tab (in which Intellisense is not working) and reoppen it. Many times this was enough for me, boring, but enough.
