  • Errors, warnings and suggestions are complemented by hints, which are by far the most non-intrusive way to recommend coding improvements.

  • .NET Framework classes were annotated with custom attributes to make ReSharper analyze your code even better than before - for instance, to let it know where format strings should be passed or where null values can or cannot be assigned. You can also use these custom attributes to annotate your own source code, as well as library symbols that you don't have source code for.

  • Code Cleanup- a powerful successor to Reformat Code. By running Code Cleanup, you can instantly apply a dozen of actions, including arranging 'this' qualifiers, removing code redundancies, migrating to auto-properties, optimizing using directives, and many more.

New members of the refactoring family are available, including Convert Method to Indexer refactoring, Convert Indexer to Method refactoring, Convert Static to Extension Method refactoring, Convert Extension Method to Plain Static refactoring, Convert Property to Auto-Property refactoring, Convert Anonymous to Named Type refactoring, and Inline Method refactoring. All refactorings that are not C# 3.0-specific are now available for Visual Basic 8.

  • Recent Edits- a drop-down list similar to existing Go To features that shows files and symbols that you recently modified.

  • Go to Type/ Symbol/ File features allow you to display destination types/symbols/files in the Find Results window.

  • To-do items are now discoverable in identifiers and strings.

  • File Structure, Go to File Member, and Go to Next/Previous Member all support XML and XAML.

  • Vast improvements in Quick Documentation, including hyperlinks to related items, back/forward navigation, "read more" links and navigating to source.
