In this chapter, you will be learning about .NET MAUI Essentials and how it enables you to access platform-specific APIs without having to worry about any of the platform-specific complexities. Two concrete examples are requesting permissions on each platform and accessing the device’s geolocation information. You will explore what is required if you really do need to interact with platform-specific APIs that have not been abstracted for you. Finally, you will cover multiple techniques, concepts, and architectures that enable you to tweak the UI and behavior of your applications based on the platforms they are running on.
