Analyze code quality
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 them automatically, in the best possible way.
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 to 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.
Visual Studio 2015 and C# 6.0
Newest updates from Microsoft are already supported, including Visual Studio 2015 Preview and many C# 6.0 features such as static usings and the ?. operator.
ReSharper 9 introduces support for regular expressions with code completion, error highlighting, quick-fixes and a Validation Utility.
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.
Use .NET languages and C++
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.
Use both .NET languages and C++
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 ReSharper Ultimate is priced roughly the same as the two-license combo and additionally makes the developer eligible to use dotCover, dotTrace and dotMemory.
Have profilers readily at hand
ReSharper and dotCover are a part of a .NET developer's daily work but profilers are a different beast. Sometimes developers don't care much about performance bottlenecks and memory leaks until late in the development cycle. Still, having familiar tools at hand is an important prerequisite to confidently solving performance and memory consumption problems as they arise. ReSharper Ultimate includes both dotTrace and dotMemory, and even if they are not put to practice every day, they are readily available when it comes to the crunch.
Enjoy uniform maintenance
Traditionally, JetBrains .NET tools have been distributed using different licensing schemes, which would introduce unnecessary confusion at times for customers with licenses to more than a single tool. To make things easier, ReSharper Ultimate always includes a 1-year subscription. This means you won't have to monitor subscription expiration dates for every tool, but instead you can upgrade them all for free during a year after purchase date. As soon as the first year of free subscription expires, you can renew all covered products for one more year, in one go.
