I have one problem. When I press ctrl + space the Intellisense window will not show, but it works! I can chose any word by arrows press enter and then it one will appear, but the windows with this words not show. Some times it showed sometimes no. This problem occurs only when I am working with TFS project.
This is 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
UPD I have just committed changes, and the same problem occurred on colleges PC).
