I use Xamarin Studio and I write applications for iOs on C#. I need to bind obj C library (libAdWired.a) to C# platform, in order to be able to use it directly from C#. First of all, I have to bind objective-C to C#, so I create a Binding Project in Xamarin. Then I include an objective-C lib to the project (libAdWired.a) and create inside ApiDefenition.cs a binding-code.

namespace Adwired
{
[BaseType (typeof(UIView))]
interface AWView
{
    [Export ("delegate", ArgumentSemantic.Assign)]
    NSObject Delegate { get; set; }

    [Export ("bannerDidStartSelector", ArgumentSemantic.Assign)]
    Selector BannerDidStartSelector { get; set; }

    [Export ("bannerDidStopSelector", ArgumentSemantic.Assign)]
    Selector BannerDidStopSelector { get; set; }

    [Export ("bannerDidFailSelector", ArgumentSemantic.Assign)]
    Selector BannerDidFailSelector { get; set; }

    [Export ("placeId", ArgumentSemantic.Copy)]
    string PlaceId { get; set; }

    [Export ("keywords", ArgumentSemantic.Copy)]
    NSObject [] Keywords { get; set; }

    [Export ("bannerType")]
    AWBannerType BannerType { get; }

    [Export ("closeAnimation")]
    AWViewAnimation CloseAnimation { get; set; }

    [Export ("frameLocked")]
    bool FrameLocked { get; set; }

    [Export ("frameLock", ArgumentSemantic.Assign)]
    RectangleF FrameLock { get; set; }

    [Export ("fullscreenOrientationMask")]
    AWBannerOrientation FullscreenOrientationMask { get; set; }

    [Static, Export ("debugMode")]
    bool DebugMode { set; }

    [Static, Export ("isDebugMode")]
    bool IsDebugMode { get; }

    [Static, Export ("uniqueIdentifier")]
    string UniqueIdentifier { get; }

    [Static, Export ("uniqueIdentifier2")]
    string UniqueIdentifier2 { get; }

    [Static, Export ("initialize")]
    void Initialize ();

    [Export ("initWithDelegate:")]
    IntPtr Constructor (NSObject aDelegate);

    [Export ("initWithDelegate:rotationEnabled:")]
    IntPtr Constructor (NSObject aDelegate, bool rotationEnabled);

    [Export ("loadForPlaceId:")]
    bool LoadForPlaceId (string placeId);

    [Export ("loadForPlaceId:keywords:")]
    bool LoadForPlaceId (string placeId, NSObject [] keywords);

    [Static, Export ("checkForPlaceId:keywords:")]
    bool CheckForPlaceId (string placeId, NSObject [] keywords);

    [Export ("changeOrientation:")]
    void ChangeOrientation (UIInterfaceOrientation orientation);

    [Export ("removeWithAnimation:")]
    void RemoveWithAnimation (AWViewAnimation animation);

    [Export ("showInView:placeId:")]
    void ShowInView (UIView view, string placeId);

    [Export ("showInView:placeId:keywords:")]
    void ShowInView (UIView view, string placeId, NSObject [] keywords);

    [Export ("showBannerOnView:placeId:context:")]
    void ShowBannerOnView (UIView baseView, string placeId, string context);

    [Export ("hideBanner")]
    void HideBanner ();

    [Export ("modifyView")]
    void ModifyView ();
}


// Delegate
[BaseType (typeof(NSObject))]
[Model]
interface AWDelegate
{
    [Export ("bannerDidStart:")]
    void BannerDidStart(AWView bannerView);

    [Export ("bannerDidStop:")]
    void BannerDidStop(AWView bannerView);

    [Export ("bannerDidFail:")]
    void BannerDidFail(AWView bannerView);
}
public enum AWViewAnimation
{
    Undefined = 0,
    None,
    Simple,
    Thin
}

public enum AWBannerType
{
    Undefined = 0,
    Standart,
    Fullscreen,
    Slim,
    Custom
}

public enum AWBannerOrientation
{
    None = 0,
    Portrait           = 1 << 0,
    PortraitUpsideDown = 1 << 1,
    LandscapeLeft      = 1 << 2,
    LandscapeRight     = 1 << 3,
    OrientationAll = 8
}
}

And finally as output i have a C# binding dll (AdWired.dll).

Then, I add this DLL into my main C# project. i want to use AWView class from this DLL. So i instantiate this class with following code AWView _banner = new AWView(). When I deploy my application to a device i see "Wrapper type 'AdWired.AWView' is missing its native ObjectiveC class 'AWView'".

I tried to find this class in obj C lib, and i found it. However...

I am stuck now, so any help or advice will be appreciated.

PS. Its runtime error.
