Properly Implementing the Template Method Pattern

ConcreteTemplateA.cs

using System;

public class ConcreteTemplateA : Template
{
    protected override void DoThis()
    {
        // Do this
    }

    protected override void DoThat()
    {
        // Do that
    }

    protected override void DoOther()
    {
        // Do other
    }
}

ConcreteTemplateB.cs

using System;

public class ConcreteTemplateB : Template
{
    protected override void DoThis()
    {
        // Do this
    }

    protected override void DoThat()
    {
        // Do that
    }

    protected override void DoOther()
    {
        // Do other
    }
}

Template.cs

using System;

/// <summary>
/// An example Template Method pattern.
/// <para>The Template Method pattern is a behavioral 
/// design pattern, whose purpose is to define the 
/// skeleton of an algorithm in an operation, deferring 
/// some steps to subclasses.</para>
/// </summary>
public abstract class Template
{
    public void Process()
    {
        DoThis();
        DoThat();
        DoOther();
    }

    protected abstract void DoThis();

    protected abstract void DoThat();

    protected abstract void DoOther();
}
