I upgraded to 8.0.1 this morning and since then the upgrade intellisense auto list members has not been working. It appears that the VS option "Options -> Text Editor -> All Languages (or C#) -> Auto list members" is being cleared. I go into Options and set it to checked and it works in the current document. However, when I go to a different document in the IDE, I get the same behavior, and when I go back into Options the option is unchecked again.
I reinstalled 8.0.0 and the issue no longer occurs. Is anyone else seeing this behavior? I don't think there's anything unque with the solutions I am using, other than it is on the large side with 84 projects I suppose.
