Remarks
Xamarin.iOS will export any interfaces with this attribute as a protocol to Objective-C, and any classes that implement these interfaces will be marked as implementing the corresponding protocol when exported to Objective-C.
// This will create an Objective-C protocol called 'IMyProtocol', with one required member ('requiredMethod')
[Protocol ("IMyProtocol")]
interface IMyProtocol
{
[Export ("requiredMethod")]
void RequiredMethod ();
}
// This will export the equivalent of "@interface MyClass : NSObject <IMyProtocol>" to Objective-C.
class MyClass : NSObject, IMyProtocol
{
void RequiredMethod ()
{
}
}

Properties
| BackwardsCompatibleCodeGeneration |
This property indicates whether the binding generator will generate backwards-compatible code for the protocol in question. In particular, if this property is true, then the binding generator will generate extension methods for optional members and ProtocolMemberAttribute attributes on the protocol interface for all protocol members. |
| FormalSince | |
| IsInformal |
Whether the Objective-C protocol is an informal protocol. |
| Name |
The name of the protocol. |
