In this video, I am going to discuss Why do we need to create the Singleton Class as Sealed in C# with examples. At the end of this video, you will understand the following pointers.
1. What is the role of the sealed keyword in C#?
2. What is the role of the Private Constructor in C#?
3. Then we will discuss one concept i.e. Nested classes in C#?
4. And finally, we will discuss, why do we need to use the sealed keyword in the singleton class as we already have a private constructor within the class which will restrict the class for further inheritance.

The private constructor in c# will help us only preventing any external instantiations of the class and the sealed keyword will prevent the class inheritances.
