Why C# doesn’t supports multiple inheritance?

Its good to know that  C# Supports Multiple Inheritance . But i  wrote  my  title that it  doesn’t. Yes  it doesn’t support by Implementation inheritance but supports using Interface  Implementation.  Sounds confused??  have a look at it…

Basic Inheritance

Two types of Inheritance:
1.    Implementation Inheritance: in which class inherits one class and implement/override its methods and properties for example Control object in which System.Windows.Forms.Textbox,System.Windows.Forms.Button both inherits their self from control class. But provides different functionality
2.    Interface inheritance: in which a class inherits from Interface. For example IDisposable. It just inherits definition not implementation. Any type which does interface inheritance it means that it will provide defined functionality called as “Contract”.

Multiple Inheritance:
A class derives from more than one class it is called Multiple inheritance
Multiple inheritance allows a class to take on functionality from multiple other classes, such as allowing a class named StudentMusician to inherit from a class named Person, a class named Musician, and a class named Worker. This can be abbreviated StudentMusician : Person, Musician, Worker.
Ambiguities arise in multiple inheritance, as in the example above, if for instance the class Musician inherited from Person and Worker and the class Worker inherited from Person. There would then be the following rules:
StudentMusician: Person, Musician, Worker
Musician : Person, Worker
Worker: Person
If a compiler is looking at the class StudentMusician it needs to know whether it should join identical features together, or whether they should be separate features. For instance, it would make sense to join the “Age” features of Person together for StudentMusician. A person’s age doesn’t change if you consider them a Person, a Worker, or a Musician. It would, however, make sense to separate the feature “Name” in Person and Musician if they use a different stage name than their given name. The options of joining and separating are both valid in their own context and only the programmer knows which option is correct for the class they are designing.
Debate
There is debate as to whether multiple inheritance can be implemented simply and without ambiguity. It is often criticized for increased complexity and ambiguity, as well as versioning and maintenance problems it can cause (often summarized as the diamond problem).[1] Detractors also point out multiple inheritance implementation problems such as not being able to explicitly inherit from multiple classes and the order of inheritance changing class semantics. There are languages that address all technical issues of multiple inheritance, but the main debate remains whether implementing and using multiple inheritance is easier than using single inheritance and software design patterns.

Multiple Inheritance arises Diamond Problem

programming languages with multiple inheritance and knowledge organization, the diamond problem is an ambiguity that arises when two classes B and C inherit from A, and class D inherits from both B and C. If a method in D calls a method defined in A (and does not override it), and B and C have overridden that method differently, then via which class does it inherit: B, or C?

For example, a class Button inherits from both classes Rectangle (for appearance) and Mouse (for mouse events), and classes Rectangle and Mouse both inherit from the Object class. Now if the equals method is called for a Button object and there is no such method in the Button class but there is an over-ridden equals method in both Rectangle and Mouse, which method should be called?

It is called the “diamond problem” because of the shape of the class inheritance diagram in this situation. Class A is at the top, both B and C separately beneath it, and D joins the two together at the bottom to form a diamond shape.

C# Supports Multiple Inheritances by Interfaces only

NOTE: lots of help got from wikipedia

Happy Inheritance!!
