Inheritance is a fundamental concept in Object-Oriented Programming (OOP) that allows a new class to inherit properties and methods from an existing class. This promotes code reusability and establishes a parent-child relationship between classes. In .NET Core, as in other OOP languages, there are several types of inheritance:

1. Single Inheritance

Single inheritance is when a class inherits from only one base class. This is the most straightforward and common form of inheritance. In .NET Core, this is achieved using the : symbol.

class Animal {
    public void Eat() {
        Console.WriteLine("Animal is eating.");
    }
}

class Dog : Animal {
    public void Bark() {
        Console.WriteLine("Dog is barking.");
    }
}

2. Multilevel Inheritance

Multilevel inheritance occurs when a class is derived from another derived class, forming a chain of inheritance.

class Animal {
    public void Eat() {
        Console.WriteLine("Animal is eating.");
    }
}

class Mammal : Animal {
    public void Run() {
        Console.WriteLine("Mammal is running.");
    }
}

class Dog : Mammal {
    public void Bark() {
        Console.WriteLine("Dog is barking.");
    }
}

3. Hierarchical Inheritance

Hierarchical inheritance is when multiple classes inherit from a single base class.

class Animal {
    public void Eat() {
        Console.WriteLine("Animal is eating.");
    }
}

class Dog : Animal {
    public void Bark() {
        Console.WriteLine("Dog is barking.");
    }
}

class Cat : Animal {
    public void Meow() {
        Console.WriteLine("Cat is meowing.");
    }
}

4. Multiple Inheritance (Through Interfaces)

.NET Core does not support multiple inheritance with classes directly. However, it can be achieved through interfaces. A class can implement multiple interfaces, thus inheriting the behavior defined in those interfaces.

interface IAnimal {
    void Eat();
}

interface IPet {
    void Play();
}

class Dog : IAnimal, IPet {
    public void Eat() {
        Console.WriteLine("Dog is eating.");
    }

    public void Play() {
        Console.WriteLine("Dog is playing.");
    }
}

5. Hybrid Inheritance (Through Interfaces)

Hybrid inheritance is a combination of two or more types of inheritance. Since C# does not support multiple inheritance with classes, hybrid inheritance is typically achieved using interfaces.
