I like to validate my application configuration upon startup. Especially when doing local development, I want to know which application settings are missing. I also like to know where I should add them. This blog shows how to implement validation of your configuration classes using data annotations.
I love how we can use appsettings.json files to configure applications in the .NET Core platform. The JSON-format feels a lot less bloated than the old XML appSettings config I used to work with. In this blog I’ll explore how to load a dictionary-style settings class as an IOption. This can be very useful when working with dependency injection.
