Look for this file, it's the one you want to change:
C:\Program Files (x86)\Microsoft Visual Studio.0\Common7\IDE\ItemTemplates\CSharp\Code33\Class\Class.cs
I think it would look something like this:
using System;
using System.Collections.Generic;
$if$ ($targetframeworkversion$ >= 3.5)using System.Linq;
$endif$using System.Text;
$if$ ($targetframeworkversion$ >= 4.5)using System.Threading.Tasks;
$endif$
namespace $rootnamespace$
{
public class $safeitemrootname$
{
}
}
I placed GitHub for future reference .
To use with other versions of VS simply change the version in the file path. Just remembering that Visual Studio 2010 behind the file is compressed in zip
format. It is unlikely to fundamentally change in future releases like the new Visual Studio 2015 or the Community edition that is free for almost everyone. In addition to .Net pass have MIT license .
