This is the first sample in the book. This sample started by typing dotnet new and creating an empty project. In the book,
we added the ASP.NET dependencies and modified Program.cs as well as created Startup.cs to add some simple "Hello World"
middleware.
To run this sample:
$ dotnet restore
Then:
$ dotnet run
To invoke the middleware and see the results, simply curl http://localhost:5000/any/url
