Hi Imran

FormStorage is now registered as a singleton with Umbraco V8's new lightject underlying dependency injection framework:

 composition.Register<IFormStorage, FormStorage>(Lifetime.Singleton);

This means you can gain access to the FormStorage by injecting it into the constructor of the class you are working in:

eg

  public class SomeCustomController : UmbracoAuthorizedJsonController
    {
        private readonly IFormStorage _formStorage;


        public SomeCustomController(IFormStorage formStorage)
        {
            _formStorage = formStorage;
        }

Then you can use _formStorage in your methods..

Failing that, eg you are choosing not to use DI, or it would be difficult to implement in your custom code then you can use the service locator pattern to retrieve the instance of IFormStorage:

IFormStorage _formStorage = Current.Factory.GetInstance<IFormStorage>();
