Why do I have this problem, and what can I do to fix it?
I have resharper installed too, but it seems it's not the problem in my case.
Code suggestions are disabled also (method parameters for example).
I think the problem is with the VS installation, because at the end of the process the following message is shown: "The event log file is full".
in the end, it seems VS12 doesn't activate intellisense by default (you need to use CTRL+Space to get autocomplete and code suggestions).
I had to enable it from the Tools-This is fairly common when you're on a trial version of resharper and the trial runs out.
I assume R# turns these settings off and replaces it with the R# version, so when R# goes away, so does any kind of code completion.I wish there was a better solution to this problem, but this is the only thing that seems to work.
