Having used Xamarin Studio for most of the Xamarin University classes I must say I’m impressed, one notable drawback compared to Visual Studio is the lack of Resharper.
While not new news I thought it should help other newcomers to highlight that Xamarin Studio has an option to enable some additional Resharper style assistance. To do this in the Preferences->Text Editor->Source Analysis check the option ‘Enable source analysis of open files’.
Once enabled the vertical scroll bar displays indicators for potential problems, hovering the cursor over this displays a tooltip describing the problem. Coloured squiggly underlines are also used to highlight the problem.
The ⌥ + ⏎ key shortcut will jump to the quick fix.
Or right click on the problem area of code and select the Fix option.
