The type or namespace name 'Json' does not exist in the namespace 'System.Runtime.Serialization'

I need to build the Constant Contact C# library against .net 3.5 because that is what we are currently using.  When I switch to 3.5 and try to build I get the following error:

The type or namespace name 'Json' does not exist in the namespace 'System.Runtime.Serialization' (are you missing an assembly reference?)

It can no longer find JSON under System.Runtime.Serialization.  What can I do to fix this?  This is in the Component.cs and Extensions.cs file.

Thanks
Mike

In 3.5, the System.Runtime.Serialization.Json reference needs to have the a special assembly added as a reference.  The actual code is in the System.ServiceModel.Web assembly.  You would need to add this as a reference manually.   You can see this documentation for 3.5 for more information: http://msdn.microsoft.com/en-us/library/system.runtime.serialization.json.datacontractjsonserializer...

Thank you, worked perfect.

Now I am getting one more error.   I will start a new thread.
