Method Group Conversion allows you to simply assign the
name of a method to a delegate, without usingnew or explicitly invoking
the delegate’s constructor.
Computer.StaticCompute is actually called a method group because the method could be overloaded and this name could refer to a group of methods. In this case, the method group Computer.StaticCompute has one method in it.

C# allows you to directly assign a delegate from a method
group. When you create the delegate instances via new, you pass the method
group in the constructor
What is delegate, use of delegate in c# sharp dot .Net, real
world scenarios and live code example of delegate, C# allows you to directly
assign a delegate from a method group
