Are all C# methods virtual?

No, not all C# methods are virtual. In fact, just as in C++, all methods are considered non-virtual by default. So, virtual methods must be declared virtual.

using System;
 
public class ExampleClass
{
   public void NonVirtualMethod()
   {
   }
 
   public virtual void VirtualMethod()
   {
   }
}
