You make it virtual so that in a descendat class, you can override the get or set method

class a
{
   public virtual string Name
  {
   get  { return "Base Name"; }
  }
}

class b : a
{
    public override string Name
   {
      get{return "Descendant Name";}
   }
}

Refere to this site, it has some good information

Yeah I know that. But is the necessity in that class i.e PropertyChangedEventArgs  , to be virtual.

In which scenario  PropertyChangedEventArgs   property name will be  overidden in derived class

I guess Microsoft just wanted to build in some flexibility. Here's an interesting article on PropertyChangedEventArgs:
