MonoTouch 4.2 does not support System.ServiceModel.EndpointAddress() when running on the device (works on the simulator)

I am using MonoTouch 4.2.1 with MonoDevelop 2.8 Beta 2 and XCode 4. We are trying to call a .Net web service method through classes generated by the slsvcutil proxy generator.

When testing the app on the iPhone simulator, the code is working and we succeed to connect to the server and send web services requests.

However, when testing the app on a device (iPhone 4 with iOS 4.3.5), the app fails to connect to the server when calling System.ServiceModel.EndpointAddress() constructor.

Note that it was working fine with MonoTouch 4.0.7.

we get the error:

Attempting to JIT compile method 'System.Linq.Enumerable:FirstOrDefault<System.ServiceModel.Description.OperationDescription> (System.Collections.Generic.IEnumerable`1<System.ServiceModel.Description.OperationDescription>,System.Func`2<System.ServiceModel.Description.OperationDescrip开发者_开发技巧tion, bool>)' while running with --aot-only.

It is the following line that seems to crash:

new System.ServiceModel.EndpointAddress(
      string.Format(System.Globalization.CultureInfo.InvariantCulture, "http://{0}:{1}/Dartfish/RemoteControlServices/",
      address, port)));

Error stack:

It's don't seems to be a compiler issue since compiler option is "Link SDK assemblies only" as it should be. Someone know how to fix this crash or if is a new MonoTouch limitation/a bug in the last MonoTouch version?

Have you tried the current version and/or contacted the support personal for MonoTouch? Your only question seems like it would better directed at the support staff at MonoTouch and not here.
