Visual Studio无法识别MvxFragment的BindingInflate函数

Question

I have the following class:

using Cirrious.MvvmCross.Binding.BindingContext;
using Cirrious.MvvmCross.Droid.Views;
using Cirrious.MvvmCross.Droid.Fragging;
using Cirrious.MvvmCross.Droid.Fragging.Fragments;

public class DifficultyItemFragment : MvxFragment
{
    public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
    {
        var ignored = base.OnCreateView(inflater, container, savedInstanceState);
        return this.BindingInflate(Resource.Layout.DifficultyItemFragment, null);
    }
}

and I get the following error:

 Error  8   ...'QuickShift.Android.Views.DifficultyItemFragment' does not contain a definition for 'BindingInflate' and no extension method 'BindingInflate' accepting a first argument of type 'QuickShift.Android.Views.DifficultyItemFragment' could be found (are you missing a using directive or an assembly reference?)

I looked at the MvvmCross source code and BindingInflate does indeed exist within the BindingContext namespace.

Am I missing something?? I have all the necessary libraries referenced, including Xamarin.Android.Support.v4

UPDATE:

I've created a sample project in VS 2013 to illustrate the problem. You'll notice that in Fragment1.cs the same problem exists:

BindingInflate is actually an extension method. You need to import the correct namespace (for version 3.5.x).

using Cirrious.MvvmCross.Binding.Droid.BindingContext;

For version 4.x, MvvmCross has reorganized the namespaces. The correct import is:

using MvvmCross.Binding.Droid.BindingContext;

EDIT: Added version info to answer and included updated namespace for v4.x
