Incorrect C# Error Reports

I'm using ReSharper 7.1.1000.900 on Visual Studio 2012 11.0.51106.1.

The following code fragment relates:

        public delegate void ExcelAction();

        .........

        public static void QueueAsMacro(ExcelAction action)
        {
            QueueAsMacro(delegate { action(); }, null); /// <<<<<< Problem Line
        }
 
        public static void QueueAsMacro(SendOrPostCallback callback, object state)
        {
            if (!SynchronizationManager.IsInstalled)
                throw new InvalidOperationException("SynchronizationManager is not registered.");
 
            SynchronizationManager.RunMacroSynchronization.RunAsMacroAsync(callback, state);
        }

ReSharper incorrectly identifies an error in the 'Problem Line': Method 'QueueAsMacro' has 1 parameter(s) but is invoked with 2 argument(s).
As a consequence, that method (the first instance) is also marked with a warning: Method 'QueueAsMacro' is never used. Function is recursive on all paths.

The code compiles and runs correctly.
