Many-to-many relationships throw error when serialized

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Set the Serialization Mode on the .dbml to Unidirectional.[1]
2. Set the IncludeDataContract option in Entities.cst to true.
3. Generate the entities.
4. Place a [field: NonSerialized] attribute on the public events in the 
entity base class.[2]
5. Attempt to serialize an entity with a many-to-many relationship using 
the DataContractSerializer.

What is the expected output? What do you see instead?
Expected the Entities generator to respect the .dbml Serialization Mode 
setting. Instead, the DataContract and DataMember attributes appear to 
have been placed everywhere.

What version of the product are you using?
Using release 1.3 on Windows Vista.

Please provide any additional information below.

Hi,  What error are you getting?  Are you just reporting the the generated code 
is
different then you expected?  Plinqo has some additional support for 
serialization
that the dbml designer doesn't.  Have you tried detaching before serializing?

I was receiving a circular reference. We're upgrading to CodeSmith 5 and PLINQO 
2.0,
which is working great. I'm not sure what wasn't working in 1.3, though I 
suspect
something may have changed with VS2008 SP1? Since moving to the new templates, 
I've
deleted the error I received.
