Azure Functions, Blog, Technology, V2, ASP.NET Core, Dependency Injection

Dependency Injections on Azure Functions are not very intuitive. I’ve written many blog posts about dependency management on Azure Functions to improve testability and this was my latest one.

  • Its JSON structure is quite complex so that it’s not that easy to read at a glance,
  • It’s hard to validate if there is a typo or not, and
  • We only know if the resource...
