You have created an ASP.NET server control named Shopping Cart for use by other developers. Some developers report that the Shopping Cart control does not function properly with ViewState disabled. You want to ensure that all instances of the Shopping Cart control work even if View State is disabled. What should you do？（）

• ARequire developers to set EnableViewStateMac to true.
• BStore state in ControlState instead of ViewState.
• CSerialize the state into an Application state entry called "MyControl".
• DRequire developers to change the session state mode to SQLServer.
