title: Problem With LINQ Model - Can't Assign NULL To Nullable Boolean!
body: <p>I have a LINQ model containing an entity which is populated by a stored procedure.  A couple of the fields returned by the procedure are nullable bit fields, so I've created these as nullable booleans on the model.  I'd expect this to work fine, but when I run my application I get the following exception from <code>System.Runtime.Serialization</code>...</p>
  
  <blockquote>
    <p>The formatter threw an exception while trying to deserialize the
    message: There was an error while trying to deserialize parameter
    urn:Nbs.PrePaidCards.ChargebackService:GetUnlinkedChargebacksAndRepresentmentsResult.
    The InnerException message was 'ValueType 'System.Boolean' cannot be
    null.'.  Please see InnerException for more details.</p>
  </blockquote>
  
  <p>Now I'd understand this if I was trying to populate a regular <code>bool</code> field with a <code>null</code>, but since the property is <code>Nullable</code>, this has me a bit stumped!</p>
  
  <p>Had anyone else had this problem and know how to fix it? </p>
  
  <p>Thanks</p>
