How do you default a new class to public when creating it in Visual Studio?

Question

In VS2012 it's as easy as going to C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\ItemTemplates\CSharp\Code\1033\Class and editing the Class.cs file.

No need to unzip or rebuild cache. A very positive change if you ask me.

VS2015: C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\ItemTemplates\CSharp\Code\1033\Class

VS2017(RC): C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Common7\IDE\ItemTemplates\CSharp\Code\1033\Class

VS2017(Professional): C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\IDE\ItemTemplates\CSharp\Code\1033\Class

VS2019 (Enterprise): C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\Common7\IDE\ItemTemplates\CSharp\Code\1033\Class\Class.cs

VS2019 (Professional): C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\Common7\IDE\ItemTemplates\CSharp\Code\1033\Class\Class.cs

Outdated

VS2019 (Preview): C:\Program Files (x86)\Microsoft Visual Studio\2019\Preview\Common7\IDE\ItemTemplates\CSharp\Code\1033\Class\Class.cs

You need to modify the file located in C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\ItemTemplates\CSharp\Code\1033.

Visual Studio 2010 (10.0) and below: There is a zip file in there called Class.zip. Unpack this, edit the file to put in your public keyword then re-pack it (make sure you backup the original).

After this, make sure VS rebuilds it's cache (which is just the zipfiles unzipped into directories in C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\ItemTemplatesCache) by opening a Visual Studio command shell and execute the following command:

devenv /installvstemplates

Visual Studio 2012 (11.0) and up: See the answer by @JochemKempe, as it's much easier to change this now, just by editing a single file (no unzipping or rezipping).

UPDATE: Don't forget to open your preferred text editor with admin privileges before you do any edit.

To create a Public class by default for Visual Studio 2012:

Edit this file:

C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\ItemTemplates\CSharp\Code\1033\Class\Class.cs

To look 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 $safeitemrootname$
    {
    }
}

You could either create your own project template, or modify the existing one. All these project files are template-driven, so you can alter them and/or add your own.
