JetBrains Resharper is a Visual Studio .NET add-in that brings intelligent C# code editing and coding assistance features to VS.NET. By intelligent features we mean usage search, powerful refactorings, smart type completion, using directive assistant and more. In brief, ReSharper truly understands C# code.
JetBrains ReSharper UnitRun is a free add-in to Visual Studio 2005 that enables rich ReSharper TDD support for everyone. Simply put it is ReSharper unit testing functionality released separately.
We at JetBrains believe that making tools for developers should greatly involve listening to developers. Our Early Access Program lets development community closely participate in discussions devoted to ReSharper and influence development planning, from early stages onwards.
Early Access Program allows you to try pre-release versions of our software to evaluate features that will be added to the next release.
It is important to distinguish EAP from traditional pre-release software. Please note that the quality of EAP versions may at times be way below even usual beta standards.
