Returning a NULL object reference error when loading the web application

I'm returning a null object reference when running the inital page.  The error occurs in the SavePageState method calling LoadProviders();

the _provider = _providers[section.DefaultProvider]; is returning a null value

I noticed that my section.providers returns a count of 0 from below.

The error occurs at _provider.SavePageState(name,viewstate); (actually error NullReferenceException was unhandled by user code.  I see a first and second in the viewstate object the first is Null.

Please note I'm not using the WCF since it was not necessary.


var section = (ViewStateProviderServiceSection)

                        // Load all registered providers
                        _providers = new ViewStateProviderCollection();

                            (section.Providers, _providers,

                        // Set _provider to the default provider
                        _provider = _providers[section.DefaultProvider];
