Data Annotation validation with dependency injection in a business service
What I love about data annotations and validation attributes, is that the validation rules are defined very close to the class: when you open it up, you can view all the rules.

In this blog, I’ll show how to use the RichardSzalay.MockHttp package together with Kiota.
