Too Long; Didn't Read
The Top 4 Nuget packages are: Automapper, Mediatr, Swagger and Fluent Validation. These packages make for an easier development experience and make my code much easier to maintain. If I've missed a package that you think is super useful, please share it in the comments section below. I would recommend that you consider them for your own projects in the future. I'm a firm believer that you should make your life as easy as possible as a developer, by using tried and tested packages.
