WCF cannot deserialise nested arrays

[=?Utf-8?B?QmFybmV5TGlnaHQ=?=]

Hi,

I have a WCF service contract which has message containing a List<MyType>
data member where MyType consists of a string Key and object Value.

As expected this gets exposed as a MyType[] array in the service reference.

In the client, I dynamically add Key/Value entries in the list.

This works fine as long as I use simple types in the client, but I need to
add a nested array into this list. That is, I need an element in the list
which is itself a MyType[] array.

When I send a message with a nested array, the server simply 'ignores' the
message. I know that the message arrives as I've got an
IDispatchMessageInspector class which logs everything that's received.

Is there a way for me to acheive this, without going down the manually
deserializing route?

Many thanks,

Barney.

I have found the solution: you need to assign the
[KnownType(typeof(List<MyType>))] attribute to the message class.
