Example of a generated Task return value for `[Async (ResultTypeName = "FetchRepositoriesWithCompletionArgs")]`, using `Action<bool, NSError, NSArray>` as the delegate type. This results in generic return value names like "Arg1".

FetchRepositoriesWithCompletionArgsAction.cs

public class FetchRepositoriesWithCompletionArgs {
	public bool Arg1 { get; set; }
	public NSError Arg2 { get; set; }
	public NSArray Arg3 { get; set; }
	
	public FetchRepositoriesWithCompletionArgs (bool arg1, NSError arg2, NSArray arg3) {
		this.Arg1 = arg1;
		this.Arg2 = arg2;
		this.Arg3 = arg3;
	}
}
