ReSharper Early Access Program

Welcome to ReSharper Ultimate 2017.1 Early Access Program (EAP)! The program provides access to pre-release builds of ReSharper 2017.1 and other ReSharper Ultimate tools: ReSharper C++, dotTrace, dotMemory, dotCover, dotPeek, and TeamCity plug-in for Visual Studio.

As this is pre-release software, stability of builds presented here, as well as their applicability to a certain purpose, may (and most probably will) vary. Please use the builds at your own risk. In addition, please note that:

  • All EAP builds are valid for 30 days from release date and do not require a license.
  • All products that integrate into Visual Studio support Visual Studio 2017 RC, 2015, 2013, 2012 and 2010.
  • The ReSharper Ultimate installer will remove all previous installations of ReSharper and other JetBrains .NET tools from Visual Studio.

Please use ReSharper issue tracker to report bugs and suggest features.

(If you're looking for the latest stable version of ReSharper, please go to ReSharper Downloads instead.)
