I'm running Mono 2.10 and I've just upgrated to Monotouch 4.0.
An error occurred in my application:
System.NullReferenceException: Object reference not set to an instance of an object

What's going on? Thank you.
P.S. With the previous version of MT (3.2.6), code was working perfectly.
UPDATE 1:
I've recompiled the application. Now the exception is the following:
System.Net.WebException: There was an error on processing web request: Status code 400(BadRequest): Bad Request

UPDATE 2:
I'm running mono version 2.10.5 and MT 4.0.6. I'm using WCF and try to call an external web service.
I use the following snippet of code to call the WS:
CustomBinding custom = new CustomBinding(new BinaryMessageEncodingBindingElement(),
new HttpTransportBindingElement()
{
MaxReceivedMessageSize = 2147483647,
MaxBufferSize = 2147483647
}
);
EndpointAddress endpoint = new EndpointAddress(myUrl);
client = new MyServiceClient(custom, endpoint);
This exception is caught:
System.Net.WebException: There was an error on processing web request: Status code 400(BadRequest): Bad Request

If I use basicHttpBinding nothing happens. The message seems to be lost around the network.
client = new MyServiceClient(new BasicHttpBinding(BasicHttpSecurityMode.None), new EndpointAddress(myUrl + "/basic"));
The structure returned from the WS contains a list of MyClass elements. MyClass class has been tagged with [DataContract attribute] and members with [DataMember] attribute. If the service returns only strings, int or enums, the result is ok.
NOTE: Using mono version 2.10 and MT 3.2.6, the WS works in both situations.
Any suggestions? Thank you in advance.
