.NET Binding to C++ Messaging does not handle .NET arrays fluently

If I add the following to the map example:

  byte[] myBytes = new byte[3] { 102, 111, 111};
  content["myBytes"] = byBytes;

I get a NotImplementedException.  
Is this a known todo item?

Presumably the dotnet map implementation is intended 
to interoperate with the Java MapMessage, including 
distinguishing between getBytes(), getString() 
and  setBytes(), setString()].
