Solution 1

In your DispatcherTimer class, you declare a Start() method but you do not give it a body (i.e.: you do not implement the method). You should have:

C#

class DispatcherTimer
{
   public void Start()
   {
      // Your implementation of the Start() method
   }
}

or create the class as abstract and the method as virtual:

C#

abstract class DispatcherTimer
{
   public virtual void Start();
}

Since I do not have a clue about what you want to do, I cannot decently help you to implement. Sorry.

Solution 2

First we need to add this NameSpace
using System.Windows.Threading;

After that we need to add Windowsbase.dll Assembly
Now My solution working fine

Thanks to all
