+TargetMilestone: ---
+Summary: Remoting serialization problem with array of arrays
+Description of Problem:
+We are passing array of array of our custom object (ie not framework) as a
+parameter to remote methods. This works fine between to .NET boxes or if
+the server is running on mono (linux), but fails if one of the server is
+running on windows and client on mono (linux). We are actually using
+interfaces, but the behavior is the same. 
+HappyHello[][] hello = ....
+Actual Results:
+The exception that is returned is a rethrown exception (coming from the
+server) as a serialization error:
+  at
+(System.String assembly) [0x00000]
+  at
+(System.Reflection.Assembly assembly) [0x00000]
+  at
+(System.IO.BinaryWriter writer, System.Type type) [0x00000]
+  at
+(System.IO.BinaryWriter writer, Int64 id, System.Array array) [0x00000]
+  at System.Runtime.Serialization.Formatters.Binary.ObjectWriter.WriteArray
+(System.IO.BinaryWriter writer, Int64 id, System.Array array) [0x00000]
+  at
+(System.IO.BinaryWriter writer, System.Object obj, Boolean isValueObject)
+  at
+(System.IO.BinaryWriter writer) [0x00000]
+  at
+(System.IO.BinaryWriter writer, System.Object obj,
+System.Runtime.Remoting.Messaging.Header[] headers) [0x00000]
+  at
+(System.IO.BinaryWriter writer, System.Object obj,
+System.Runtime.Remoting.Messaging.Header[] headers, ISurrogateSelector
+surrogateSelector, StreamingContext context, FormatterAssemblyStyle
+assemblyFormat, FormatterTypeStyle typeFormat) [0x00000]
+  at
+(System.IO.Stream serializationStream, System.Object graph,
+System.Runtime.Remoting.Messaging.Header[] headers) [0x00000]
+  at
+(IMessage msg) [0x00000] 
+Expected Results:
+Object to be passed over successfully
+How often does this happen? 
+Every time
+Additional Information:
+The client is not serializing the object[][] properly which causes the
+server to throw the exception. Like I mentioned above, if the server is
+running on mono, the windows client serializes properly and the server does
+not throw and error. Also, if I change it to only be one array of
+HappyHello, the code works fine on both platforms.
