I noticed a strange behaviour in my VS2012 installation. I use VS2012 Pro and ReSharper 7. Intellisense is just not showing code suggestions anymore. I found a few related questions in my research but they always had a slightly different setup going and none could solve my problem:
Intellisense is working but, it's not showing the tooltip
about selected member functions/Properties anymore.
If I take a look at the C# Text Editor Settings in
Tools -> Options -> Text Editor -> C# -> General
Most of the times the two necessary boxes Auto List Members and Parameter Information are selected. However, code suggestions in Intellisense don't work. Sometimes, when I look at the described settings, they are unselected.
Selecting them will make code suggestions work as in VS2010 but, only once. When I check the settings afterwards, they are most likely still selected, but code suggestions are not working anymore.
Some people suggested deleting the %AppData%\Roaming\Microsoft\VisualStudio\11.0
Folder, which did not work for me. I also tried to reset all changes, which also didn't help at all.
Tools -> Import and Export Settings -> Reset
What in the world could make Visual Studio to just forget its settings and trigger such an irrational behavior?
-edit-
I display the code suggestions by pressing CTRL+Alt+Space. However, I have to press that shortcut every time I want to see the suggestions. It has to be possible to automatically display them every time, when possible?
