Serialization error calling get_statistics_by_virtual

Using iControl for .NET v11.3 with LTM 12.1.2, I am attempting to use get_statistics_by_virtual for a Client SSL Profile using the iControl for Microsoft.NET.

Is this a WSDL definition issue for .NET? I am calling a number of methods that take jagged arrays, but this is the only one where I construct the arrays rather than passing in one I received from another iControl method, and the only one defined as String[][].

Note: f5Cp acquired earlier as LocalLBProfileClientSSL
var pArray = new string[1];
var pVsArray = new string[1][];
pArray[0] = pName;
pVsArray[0] = new string[1];
pVsArray[0][0] = vsName;
var profileClientSslStatistics = f5Cp.get_statistics_by_virtual(pArray, pVsArray);

.. stack trace and exception information mostly removed as this site kept identifying that as SPAM
