ReSharper Ultimate is a license that combines all individual JetBrains .NET tools, as well as ReSharper C++. Each ReSharper Ultimate license allows a single developer to use ReSharper, ReSharper C++, dotCover, dotTrace and dotMemory. If a single developer uses Visual Studio to code both in C# (or VB.NET, or TypeScript, or other languages supported by mainline ReSharper) and in C++, they would probably want to have ReSharper help them out in both worlds. Purchasing ReSharper and ReSharper C++ for this developer is a valid option but buying ReSharper Ultimate will actually cost you less than the two-license combo and will additionally make the developer eligible to use dotCover, dotTrace and dotMemory.

Analyze code quality
On-the-fly code quality analysis is available in C#, VB.NET, XAML, ASP.NET, ASP.NET MVC, jаvascript, TypeScript, CSS, HTML, and XML. You'll know right away if your code needs to be improved.

Eliminate errors and code smells
Not only does ReSharper warn you when there's a problem in your code but it provides hundreds of quick-fixes to solve problems automatically. In most cases, you can select the best quick-fix from a variety of options.

Safely change the code base
Automated solution-wide code refactorings help safely change your code base. Whether you need to revitalize legacy code or put your project structure in order, you can lean on ReSharper.

Instantly traverse the entire solution
You can instantly navigate and search in the whole solution. Jump to any file, type, or type member, or navigate from a specific symbol to its usages, base and derived symbols, or implementations.

Enjoy code editing helpers
Multiple code editing helpers include extended IntelliSense, hundreds of instant code transformations, auto-importing namespaces, rearranging code and displaying documentation.

Comply with coding standards
Code style and formatting functionality with fine-grained, language-specific settings will help you get rid of unused code and create a common coding standard for your team.
