Hi
Has anyone tried Xamarin project with dotfuscator? We are trying to use Dotfuscator with Android project, but it fails to install on device. When I disable dotfuscator, it installs succesfully.

I have followed those instructions and it builds without errors. When app is started, after splash screen, app crashes. I set dotfuscator to work with debug mode and when LoadApplication(new App()) is being called in MainActivity, it crashes with:

Thanks alper, now I got:
Unhandled Exception *: Castle.MicroKernel.ComponentActivator.ComponentActivatorException: ComponentActivator: could not instantiate namespace_replaced.Views.LoginView ---> System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.NullReferenceException: Object reference not set to an instance of an object. at namespace_replaced.Behaviors.EventHandlerBehavior.b (System.String A_0) [0x00053] in <c7dfb3b24d764a8fad8fbd5300bdb4ed>:0 at namespace_replaced.Behaviors.EventHandlerBehavior.OnAttachedTo (Xamarin.Forms.VisualElement bindable) [0x00010] in <c7dfb3b24d764a8fad8fbd5300bdb4ed>:0 at Xamarin.Forms.Behavior

I have selected only Mobile.Shared.dll in dotfuscator input.

Hi,
You have to be careful while using Dotfuscator. Because it removes some classes which it thinks unnecessary. In Xamarin project there ModelViews and Views which have no dependency between. That's why Dotfuscator might think some ModelViews are not used. And it might remove those. I guess you have to write custom rules to exclude ModelViews folder to be obfuscated.
