JetBrains ReSharper Ultimate v2015.2.20150819

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.

Why Prefer ReSharper Ultimate

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.
