If you get an exception "Response version '2.0' is not supported. The highest version supported is '1.0'" after calling an OData service from .NET framework 3.5, it means that your .NET framework is not updated for calling OData service. You need to install an update to call OData service. You will find the update in following link:
Install the update, you will be able to call OData service. It took me
one complete day to figure the problem out.
Hope this helps!
