Xamarin Code Security

I am developing an application that includes payments. I use some kind of encryption in the application, as well as some encryption and security on the server.

I want to know to protect my Xamarin code specifically when deploying to Android. I know that Xamarin.iOS is converted to native code, but Xamarin.Android deploys .Net code into a DLL that can be easily decompiled with DotPeek or any other tool, and the code will be visible, including my encryption keys or any other data, security-related security essentials between the server and my application. Obfuscation is an option, but I want to know any other options. Please help me in this matter, because it bothers me very much.

To answer your question directly: no, in fact, there is no protection against an application based on the Xamarin-compilation of Android, against reverse engineering attacks.
