After upgrading to Glass Mapper 5, unable to globally enable lazy loading

Question

In the implementation using Glass Mapper 4.3.x, I was enabling Lazy Loading in GlassMapperScCustom:

public static IDependencyResolver CreateResolver(){
            var config = new Glass.Mapper.Sc.Config();

            config.EnableLazyLoadingForCachableModels = true;

            var dependencyResolver = new DependencyResolver(config);

            var factory = dependencyResolver.ObjectConstructionFactory as AbstractConfigFactory<AbstractObjectConstructionTask>;
            factory.Remove<ModelDepthCheck>();

            return dependencyResolver;
        }

This hid some recursive model references and sloppy model properties. I am looking for an easy way to re-enable before doing a large re-factorization.

Is this possible in Glass Mapper v5?

Thanks

In version 5 config.EnableLazyLoadingForCachableModels setting was removed and "IsLazy"-setting was removed from all model property configuration, like

[SitecoreChildren(IsLazy = false)]
IEnumerable<ISitecoreItem> Children{get;set;}

You should just remove all these settings from your models, because of in V5 lazy loading was improved (it is enabled by default and disabled when request or model is cachable) and your model cann`t be a mix of lazy and non-lazy parts.

In version 5 you can force disable/enable lazy loading only when you retrieve your model, like

var data = _mvcContext.GetDataSourceItem<IData>(x => x.LazyDisabled());

or

var data = _sitecoreService.GetItem<IData>(Constants.Data.ID, x => x.LazyEnabled());

Almost all glassmapper interfaces has this parameter.

But I think that for your case it will be enough just to remove old settings when you upgrade to version 5 (at least there were no troubles on our project).
