Is there any way to use contructor injection using Autofac in a Xamarin.Android project? -

i'm throwing on xamarin.android version of existing app built heavily on microsoft stack (w8/wp8/silverlight etc..) , autofac used extensively throughout.

autofac prefers showing dependencies through constructor parameters, of course assumes i, coder, have control of creation of viewmodels/controllers, or in android's case... activities.

my question is: there way can use autofac in desired way considering android framework responsible activity creation? there can intercept activity creation resolve dependencies way autofac designed?

a possible workaround subclass activity, , mark dependencies custom attribute on writable properties.

then can use reflection yank properties out , inject them using autofac. not follow autofac's convention of marking dependencies in constructors, gets job done , injects properties mef does.

public class autofacactivity : activity {     private static containerbuilder containerbuilder { get; set; }      protected override void oncreate(bundle bundle)     {         base.oncreate (bundle);         // bootstrap         if (core.ioc.container == null) {             new bootstrapper ().bootstrap ();         }          propertyinfo[] properties =             this.gettype().getproperties(bindingflags.public | bindingflags.instance);                      foreach (var property in properties.where(p=>p.getcustomattributes(typeof(injectattribute), false).any())) {              object instance = null;             if (!core.ioc.container.tryresolve (property.propertytype, out instance)) {                 throw new invalidoperationexception ("could not resolve type " + property.propertytype.tostring ());             }              property.setvalue (this, instance);         }     } } 

this method works, feels little dirty. improvements make?
