LightInject

VTable setup of type LightInject.ServiceContainer failed in Xamarin.iOS

An important concept in app development is the D in SOLID, the Dependency inversion principle. While using this technique together with the Interface segregation principle you end up with a lot of interfaces. And with cross-platform Xamarin apps, you’ll sometimes have different implementations on iOS and Android with some fake service implementations for testing too.

When creating iOS apps using Xamarin, another good practice is to enable linking. Enabling linking will remove unused code before compilation and decreases the size of your app manyfold. There’s a difference between 80 and 20 MB, even in 2019.

Xamarin Forms has a built-in DependencyService to help manage the interfaces and their implementations, but I prefer the always excellent LightInject. And after adding LigthInject to my latest Xamarin Forms app and enabling linking, this error message appeared on startup:
