For .NET MAUI developers that would like to use Android and iOS RevenueCat functionality we have created a wrapper that is really easy to use
https://github.com/Kebechet/Maui.RevenueCat.InAppBilling
https://www.nuget.org/packages/Kebechet.Maui.RevenueCat.InAppBilling/
The wrapper serves as an abstraction for both platforms and abstracts away the need for you to use platform-specific code.
Bindings used by the wrapper are:
Android: https://github.com/Kebechet/Maui.RevenueCat.InAppBilling/tree/main/src/Maui.RevenueCat.Android
iOS: https://github.com/Kebechet/Maui.RevenueCat.InAppBilling/tree/main/src/Maui.RevenueCat.iOS
This project was created because of the mobile app we created and thus it will be supported as long as the app itself.
