JetBrains has released ReSharper 4.0, a Microsoft Visual Studio add-in that provides across-the-board support for C# 3.0 language, including LINQ, and Visual Studio 2008. In addition, the upgraded add-in features, new tools have been added, such as standard class library annotations, solution-wide analysis (for C#), versatile code cleanup, new automated refactorings, improved code-editing capabilities, and more.
"In this release, we have adopted the latest C# specifications to provide the most up-to-date support for .NET developers," said Valentin Kipiatkov, JetBrains CTO. "We not only put great effort into supporting all of the features of C# 3.0, but, in keeping with our tradition, added a number of intelligent tools to make those language features much easier to work with."
Specific improvements and new features in ReSharper 4.0 include:
Comprehensive support for C# 3.0. ReSharper not only analyzes new language constructs, but displays suggestions to help migrate to C# 3.0, as well as new warnings to comply with best programming practices. It implements C#3.0-ready refactorings and completes your code with extension methods, lambda expressions, and other new language constructs where appropriate.
Annotations for .NET Framework Class Library. Annotations come with a special set of custom attributes that greatly enhance the quality of ReSharper's code analysis, such as the location of possible NullReferenceEx.
Solution-Wide Analysis. ReSharper looks for erroneous C# code on-the-fly, without first compiling code.
Code Cleanup. A flexible code compliance and formatting tool that brings together a dozen of ReSharper features. In addition to fine-tuning formatting style, you can opt to remove code redundancies, migrate to anonymous types and auto-properties, make fields read-only if possible, optimize using directives, and revamp your C# code with many more settings. Code Cleanup works in batch mode, so that you can clean the whole project or even solution with a single shortcut.
New refactorings. New refactoring tools include Inline Method and a pack of C# 3.0-specific refactorings. For VB.NET, all refactorings that were previously limited to C# 2.0 are now available for Visual Basic 8.
Productivity features and performance enhancements include:
Complete Statement. Inserts the necessary syntax elements (braces, semicolons, etc.) and gets you in position to start the next statement, saving on excessive juggling with the caret.
CamelHumps in Code Completion. Lets you complete any symbol by entering only its uppercase characters.
Live Templates Editor and Manager. Improved UI for viewing and managing code templates.
Recent Edits. A drop-down list that shows the files and symbols that you recently modified.
ASP.NET Speedup. Accelerated analysis of ASP.NET pages.
