ReleaseAttribute Class
Definition
Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
This attribute indicates that the return value of a function is retained (the caller obtains a reference to the object returned).
[System.AttributeUsage(System.AttributeTargets.ReturnValue)]

Remarks
The Xamarin.iOS runtime uses this attribute to determine the reference counting behavior on the boundary between Objective-C and managed code.
class MyUrl : NSUrl { // NSUrl implements NSCopying
public override NSObject Clone ()
{
return base.Clone ();
}
}
In this example Xamarin.iOS will first call 'release' on the object returned by [NSUrl clone] (the call to base.Clone), then call 'retain' as the object is returned to Objective-C.
