Does anyone know if you need to pay for using xamarin at some point? If even developing free apps is it necessary to pay?
If it's an app that's part of a service, but the app is free, do you need a license or something?
Unreal Engine for example is free, but a part of the profit obtained with the software developed with it should be passed on to Epic Games, with xamarin there is something like this?
Not completely. It is part of Visual Studio now, so if you have a Visual Studio license you can use Xamarin.
The Visual Studio Community is free and can be used by individual developers, open-source project developers (for the development of these projects), educational projects / research, for educational purposes and companies with a small development team.
If you do fit one of these items, then yes, Xamarin is free to you .
You can see more about using Visual Studio / Xamarin Community at
A part that is interesting:
Visual Studio now includes Xamarin.
Xamarin will be in all versions of Visual Studio (as of the post date), including in the Community version (probably the most used), which is free for individual developers, open source projects, academic research, educational purposes and small professional teams.
You can develop and publish iOS and Android apps made with C # or F # directly with Visual Studio, with no app size limits.
In the link you have a lot more information, it's worth taking a look.
