Working with dependency injection in .NET Standard: inject your AWS clients – part 2

In part 1 of this blog post, we explored using the lightweight dependency injection (DI) provided by Microsoft.Extensions.DependencyInjection. By itself, this is great for libraries and small programs, but if you’re building a nontrivial application, you have other problems to contend with: You might have complex configuration needs (development versus production, multiple sources, etc.) How […]

Working with dependency injection in .NET Standard: inject your AWS clients – part 1

Dependency injection (DI) is a central part of any nontrivial application today. .NET has libraries like Ninject for implementing inversion of control (IOC) in their development and, as of .NET Core 1.0 (specifically, .NET Standard 1.1), lightweight DI can be provided by Microsoft.Extensions.DependencyInjection. This was used primarily in the context of developing .NET Core web applications, but it can be […]
