Taking into account the different needs of developers, terms and goals, we offer three editions of ReSharper:
ReSharper Full Edition
It includes all features for all supported languages and technologies, particularly the cross-language functionality between C# and VB.NET.
ReSharper C# Edition
If you have no need for VB.NET, you can save a buck and still work with C#, ASP.NET, XML, XAML, unit testing, build script files and the rest of the productivity features.
ReSharper Visual Basic .NET Edition
If you do not work with C#, start enjoying ReSharper's brand new extensive VB capabilities and all the other functionality as well, excluding only the C# features.
