Visual Studio multi-file Item Template having Folder with parameter replacement

You can create a C# Item Template project or manually create the item template zip file yourself.

The item template zip file should contain the following files:

• Class.cs
• Interface.cs
• MyItemTemplate.vstemplate

Then you need to copy the zip file to following folder:

• %USERPROFILE%\\Documents\\Visual Studio 2017\\Templates\\ItemTemplates\\Visual C#

Then open a new instance of Visual Studio and create/open a C# project, then open Add New Item window and choose MyItemTemplate from Visual C# Items and assing a name like MyItem1 , then the following structure will be created:

Here is the content for template files in the zip file:

Class.cs

using System;
using System.Collections.Generic;

namespace $rootnamespace$.$basename$
{
    class $safeitemrootname$: I$safeitemrootname$
    {
    }
}

Interface.cs

using System;
using System.Collections.Generic;

namespace $rootnamespace$.$basename$
{
    interface $safeitemrootname$
    {
    }
}

MyItemTemplate.vstemplate
