I've recently bought a new computer and as such have had to install visual studio 2012 onto it. When I installed it onto my last computer, everything worked fine by default; this time, auto-completion is off/not working and neither is error highlighting.

I've tried resetting the settings to their defaults but this has had no effect.

What else can I try?

Thanks.

Select Tool -> Options, then Text Editor. Under the language you are using (ie C#), go to the Advanced and make sure the Underline errors in the editor and Show live semantic errors are checked
