<para>The COM+ integration runtime creates services by inspecting the type library. When a COM+ component contains methods that pass a VARIANT, the system cannot determine the actual types to be passed prior to runtime. Therefore, when you attempt to pass a User Defined Type (UDT) within a VARIANT, it fails because it is not a known type for serialization. </para>
|
||
|
|
<para>To circumvent this problem, you can add the UDTs to the configuration file so that they can be included as known types on the appropriate service contract. In order to do so, you have to uniquely identify the UDT and the contract(s), that is, the original COM interface(s) that uses it.</para>
|
||
|
|
<para>The following example demonstrates adding two specific UDTs to the <userDefinedTypes> section of the configuration file for this purpose.</para>

<para>typeName: an optional attribute that provides the readable type name. This is not used by the runtime but helps a reader to distinguish the types.</para>
