In my code im often adding some import statements like e.g.:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Shapes;
using System.Windows.Threading;

During development some of these import statements may become unnecessary because i move the code that required these imports. In eclipse, unused imports are marked by the IDE, but in Visual Studio 2010 I couldn’t find any hint. How can i detected them?

    Visual Studio has this feature built in if you want to remove them rather than just detect them: Automatic Code Generation -> Organize usings

    The Remove Unused Usings option in the Visual Studio user interface removes using directives, using aliases, and extern aliases that are not used in the source code. There are two ways to call the operation:

    • Main Menu – On the Edit menu, point to IntelliSense, point to Organize Usings, and then click Remove Unused Usings.

    • Context Menu – Right-click anywhere inside the code editor, point to Organize Usings, and then click Remove Unused Usings.

    Franci has chimed in with the Powershell extension to VS 2010 which adds in more functionality to do this task as well as others: http://visualstudiogallery.msdn.microsoft.com/en-us/e5f41ad9-4edc-4912-bca3-91147db95b99
