How to use Middleware in ASP.NET Core (2 ways of implementing middleware) 

Middleware in ASP.Net Core is software components that are assembled into the HTTP pipeline to handle requests and responses. A middleware component can either choose to pass the request to the next component in the pipeline. Or it may choose to end the request. Middleware can perform tasks both before as well as after the next component.
Middleware is nothing but requests delegates which builds the request pipeline. In other words, we can chain requests delegates one after another to build the HTTP pipeline. And each of these requests delegates works with HTTP requests.
In this video, I will walk through how to build middleware to implement custom implementations.
Middleware can be implemented in either of two ways.
The first way is to use one of the existing extension methods:
1. Run
2. Use
3. UseWen
4. Map
5. MapWhen
Or the second way, which is building custom middleware using middleware convention.
