How do I edit the Visual Studio templates for new C# class/interface?

Question

I find myself removing the following import statements in nearly every C# file I create in Visual Studio:

using System.Collections.Generic;
using System.Linq;
using System.Text;

Of course its really easy to do this with Resharper, but I really should not have to.

There must be a few template (class, interface) somewhere in the VS directory, from which I can remove the offending lines. Where do I find these files? Is there a better way to control the default import list?

2017 through 2019 (current)

Visual Studio 2017 changed the directory location to use release year instead of its internal version number, and is additionally dependent on your edition (Professional/Enterprise/etc.):

%ProgramFiles(x86)%Microsoft Visual Studio <year><edition>Common7IDEItemTemplatesCSharpCode1033Class.cs

Year	Edition	Absolute path
2019	Community	%ProgramFiles(x86)%Microsoft Visual Studio 2019CommunityCommon7IDEItemTemplatesCSharpCode1033Class.cs
	Enterprise	%ProgramFiles(x86)%Microsoft Visual Studio 2019EnterpriseCommon7IDEItemTemplatesCSharpCode1033Class.cs
	Professional	%ProgramFiles(x86)%Microsoft Visual Studio 2019ProfessionalCommon7IDEItemTemplatesCSharpCode1033Class.cs
2017	Community	%ProgramFiles(x86)%Microsoft Visual Studio 2017CommunityCommon7IDEItemTemplatesCSharpCode1033Class.cs
