Can I buy just ReSharper or ReSharper C++?

There are several licensing options for purchasing ReSharper and ReSharper C++, however, all these options include both extensions.

1. The ReSharper license includes both ReSharper and ReSharper C++.
2. The dotUltimate license includes ReSharper, ReSharper C++, as well as Rider, our standalone .NET IDE, the dotTrace and dotMemory profilers, and the dotCover coverage tool.
3. All Products Pack will let you use all JetBrains desktop tools including ReSharper and ReSharper C++.

You can find all the licensing options on the Buy ReSharper page.
