How do you write custom middleware?

Now is the right time to create simple middleware of our own and plug it into the pipeline, so that all this theory that we have gone through ends with a practical example.

We can write either inline middleware or a neatly written class which can be configured at the startup. We will write both:

 public void Configure(IApplicationBuilder app)  {     app.Run(async context =>     {         await context.Response.WriteAsync(".NET Core 2.0 By Example");     }); }

This is the simplest middleware that one can write. This is the Run middleware and short-circuits the pipeline  after execution, and just sends a response with the message ".NET Core 2.0 By Example". It has been plugged with this code into the Configure method ...
