Using strongly typed configuration in .NET Core console app

Imagine you write a console application and you need to read the configuration from the configuration file, in the strongly typed way.

.NET core comes to help us with it. It's usually demonstrated in ASP.NET Core MVC  but it's also possible to use it in the console application. Let's see.

Let's create two configuration classes which will be used to hold the application and the module name.

The application configuration file will look like the following:

At the end, let's use it in the application.

 
All the magic (binding) is done through "Bind" method.
 

Don't forget to add the required dependencies. The project.json should contain the following:

Once you run it, the result will be:

Using the strongly typed configuration classes in .NET Core app is easy!

  Hi! Nice article! I had a question - So how do I get settings from a different class? Will I have to pass the settings class object to all the classes I call?
