WCF: Configuring Known Types

by

I guess I have found the answer now.

The configuration file I posted above looks like this:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.runtime.serialization>
    <dataContractSerializer>
      <declaredTypes>
        <add type="Person, WCFWithNoLibrary, Version=1.0.0.0,Culture=neutral,PublicKeyToken=null">
          <knownType type="Employee, WCFWithNoLibrary, Version=1.0.0.0,Culture=neutral, PublicKeyToken=null" />
        </add>
      </declaredTypes>
    </dataContractSerializer>
  </system.runtime.serialization>
  <system.serviceModel>
    ....... 
  </system.serviceModel>
</configuration>

What I just added was, the Namespace of the Person class and the Employee class. And no need for the longer Version and Culture values…. The correct configuration should be:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.runtime.serialization>
    <dataContractSerializer>
      <declaredTypes>
        <add type="WCFWithNoLibrary.Person, WCFWithNoLibrary">
          <knownType type="WCFWithNoLibrary.Employee, WCFWithNoLibrary" />
        </add>
      </declaredTypes>
    </dataContractSerializer>
  </system.runtime.serialization>
  <system.serviceModel>
    ....... 
  </system.serviceModel>
</configuration>

Now it is shorter and makes more sense. But if 3rd party libraries are used, then adding version, culture, publickeytokens would be required.
