ReSharper 4.0: General Preview

gorohoroh

We’re pretty close to launching ReSharper 4.0 EAP and now is the right time to introduce the long-awaited enhancements this major version will provide.
These can be legitimately divided into two simple categories:

• Visual Studio 2008 and C# 3.0 support
• Well… everything beyond that

Support for C# 3.0
ReSharper 3.1 already provides support for the Visual Studio 2008 environment. Version 4.0 completes this support to include the new C# features, among which are implicitly typed variables, anonymous types, object initializers, extension methods, lambda expressions and LINQ. This requires substantial updates in several major components of ReSharper functionality, which will cover:

• Code Analysis;
• Context Actions and Quick-Fixes;
• Code Completion;
• Refactorings (ReSharper 4.0 will introduce Convert to Extension Method, Convert to Automatic Property, and Convert Anonymous Type to Named, among others).

Other Enhancements

• Code Cleanup – a new tool to ensure compliance with code guidelines and enhance code structure;
• Complete Statement – another new feature that will complete language constructs and get you ready to write the next statement;
• External annotations to help cover referenced assemblies while performing null-reference analysis;
• Extended language support as VB.NET gets the full-fledged set of refactorings;
• New quick-fixes and context actions are made available for XAML files.

The wait is almost over – ReSharper 4.0 EAP is planned to open this month! Stay tuned for details.
