Web API is the RESTful API framework for ASP.NET, now simply part of the MVC framework in .NET Core. With service layers becoming an increasingly important part of all kinds of different applications, getting better at implementing this layer of an application is becoming a critically important skill. Join me while I walk you through some of the coolest, most practical and useful things I've learned while developing services using Web API and ASP.NET. We'll look at some useful patters, amazing Nuget packages that save you lots of time and effort, tips, and even some anti-patterns that hold you back. Everyone should walk away with at least a few new things they can use to develop a better service layer in ASP.NET.
