For implementing the Multiple Inheritence in our project we use Interface.
Including class liabraries are different,when you include the class liabrary means that you want to use the member of that class liabrary. But there is no method define when you want to use different different methods from the different projects then for that you have to develop the concept of multiple inheritence by using the Interface.
