    • Refactorings improvements: Change Signature refactoring gets options to make a function constexpr/const/noexcept and change the ref-qualifiers.

    • Code analysis improvements: error diagnostics in the templated code is improved significantly, providing extra information on failed enable_if conditions, ill-formed expressions inside decltype, and absent inner types.

    • New context actions to generate a function that will convert an enum to a string, convert a regular return type in a function declaration into a trailing return type and vice versa, and also insert template arguments deduced using class template argument deduction.

    • For Unreal Engine projects: postponed background indexing of the engine itself to improve the initial indexing performance and better handling of the reflection macros

    • Unit testing support for Catch 2.5

    • New supported type traits in C++11 std::has_virtual_destructor and in C++/CLI (__is_interface_class, __is_ref_array, __is_ref_class, __is_value_class, __is_sealed, __is_delegate, __has_finalizer)

  • EditorConfig properties for code syntax styles and code inspection severity levels.

  • Code inspections features for code formatting styles.

ReSharper/ReSharper C++ 2017.1

ReSharper/ReSharper C++ 2016.3

  • Support of Visual Studio 2017 RC, including the new .csproj based .NET Core projects.

  • Redesigned inspections severity options page (Code Inspection | Inspection Severity).

  • New options page (Code Editing | Third-Party Code), which allows adding C++, JavaScript, TypeScript, CSS, HTML and JSON files, folders and wildcards to be treated either as 'skipped' or 'library'. ReSharper will completely ignore 'skipped' files, and treat 'library' files as read-only — indexed for navigation, but no inspections, quick-fixes and refactorings.

  • The Usages of Symbol action lets you switch from the popup to the Find Results window before the usage search is over.

  • The Find Results window works asynchronously, meaning that you can work with the results tree while a search is in progress.

  • Recent Files and Recent Edits popups now show the path of the file, Recent Edits can also show all edits in the same method as a single entry.

  • New formats of content files (.less, .hbs, .coffee, .scss, .dart, .as, .styl) supported in Go to Text.

  • Join Lines command that quickly appends the next line after the current one.

  • ReSharper build improvements: the results of a build are now displayed in their own Build Results window, plain text logging to the Output window and/or to a file, an option to automatically run build after the solution is loaded, and proprietary NuGet package restorer that works with all supported Visual Studio versions.

  • Reworked surround templates: each non-file template can now be used for generating code, for surrounding code, or for both, which lets you reuse your custom surround templates as live templates and vice versa, reducing their total number.

  • Extract Members to Partial refactoring.

  • Move Type to Another File refactoring can be now applied to nested types.

  • Assembly dependency diagram.

  • Ability to suppress custom code inspections with comments: specify a 'suppression key' in the Edit Highlighting Pattern dialog, and then use comments like // ReSharper disable once [SuppressionKey].

ReSharper 4.0

  • Comprehensive support for Visual Studio 2008 and C# 3.0, including LINQ, implicitly typed locals and arrays, extension methods, automatic properties, lambda expressions, object & collection initializers, anonymous types, expression trees, and partial methods.

  • 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.

  • Complete Statement - a new feature that inserts necessary syntax elements (braces, semicolons etc.) and gets you to the position to start the next statement.

  • Templates Explorer and Template Editor - a redesigned set of tools to view, manage, and edit the three types of templates that ReSharper provides. From now on, you can manage and classify your templates in a special-purpose window, and edit them right in a Visual Studio code pane.

  • 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.

  • Smoother interaction with Visual Studio ecosystem. The quality of interaction with frameworks, add-ins, version control clients and other members of the Visual Studio ecosystem (.NET Compact Framework, BizTalk, and Silverlight included) is brought to a new level.
