As as developer, I was always wondering how we can remove unused using statements. It is not good practice to add namespaces which are not being used in our code. I was using Resharper to get this done.

.Net has functionality to remove unused namespaces. Below code is only display Developer Fusion on command prompt but it using 5 namespaces. This code is only using System namespace for Console class. Other namespace are not used in application.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Diagnostics;
namespace TestApplication
{
 class Program
{
 static void Main(string[] args)
{
 string blogNname = "Developer Fusion";
 Console.WriteLine(blogNname);
}
}
}


We can remove unused code by below method

Right mouse -> Organize Usings -> Remove Unused Usings

Now code will be like below

using System;
namespace TestApplication
{
 class Program
{
 static void Main(string[] args)
{
 string blogNname = "Developer Fusion";
 Console.WriteLine(blogNname);
}
}
}
