ReSharper Key Features

• Code Analysis
  ReSharper provides continuous code quality analysis in C#, XAML, XML, ASP.NET, and ASP.NET MVC, detecting errors and problems before you even compile.ReSharper applies over 900 code inspections to your code, and you can instantly see whether your current file or even your whole solution contains any errors or problems.
• Error Highlighting and Quick-Fixes
  ReSharper analyzes and highlights errors in your code while you type, without having first to compile. It also helps you solve problems instantly, by suggesting quick-fixes for most errors
• Advanced Coding Assistance
  With the aim of increasing your productivity and saving your time, ReSharper takes care of almost all coding aspects. It not only extends and improves native Visual Studio features such as code completion, but also enables you to quickly generate code using various code templates, view documentation for types and their members right in the editor, perform code transformations using the so-called "context actions", and a lot more.
• Numerous Refactorings
  Adding to the list with each new release, ReSharper provides a much wider set of automated code refactorings than Visual Studio 2005/2008/2010. Many different refactorings are available that allow you to rename, move, and safely delete symbols; introduce and inline fields, variables, and parameters; and more
• Navigation and Search
  Whenever you need to find a certain type, field, method, or any other symbol, ReSharper provides you with a variety of ways to do it. You can find a symbol by name, navigate to a symbol declaration from its reference in the code, or find and highlight symbol usages. ReSharper also allows you to thoroughly review type hierarchies and files structures, with its dedicated tool windows that are smartly integrated into Visual Studio user interface.
• Unit Testing
  ReSharper automatically detects whether your project contains unit tests of the supported test frameworks (NUnit and csUnit). It allows you to run and profile tests right from the code editor and at the same time provides you with a dedicated window where you can analyze test results and re-run unit tests
• ASP.NET Editing -
  Now you can edit ASP.NET files with both pleasure and increased productivity. Take advantage of error highlighting, quick-fixes and context actions, coding assistance, navigation, refactoring, and other features. With ReSharper, you can easily edit and refactor C# code within ASP.NET, as well as Web control properties and events, data sources and content placeholders
• NAnt and MS Build Scripts Editing
  Advanced editing capabilities, previously available only for C#, are now extended to NAnt and MSBuild scripts. As soon as you open a build script file in Visual Studio.NET with ReSharper installed, full coding assistance is available immediately
• VB Features
  ReSharper for Visual Studio 2005/2008/2010 extends a number of its smart features to Visual Basic code, including ASP pages written in VB. These include all of ReSharper's navigation and search features, as well as syntax highlighting, quick documentation lookup, and more. The greatest benefit is to be experienced by .NET developers working on mixed C# and VB projects
• XAML Editing
  With ReSharper, you get additional assistance editing XAML files whenever you work with Silverlight, WPF, or Windows Phone 7 applications, including code quality analysis on-the-fly, refactorings, code generation and rearrangement, as well as quick soluton-wide navigation.
