No default Instance is registered and cannot be automatically determined for type 'Mediachase.Commerce.Markets.IMarketService'

Vote:
 

Hi,

I have recently upgraded my episerver versions from 8.1 to 9.5. When everything seem to look ok, I am getting an isssue fetching few basic commerce elements. i am getting the below errors when trying to fetch things from the commerce data.

- No default Instance is registered and cannot be automatically determined for type 'Mediachase.Commerce.Markets.IMarketService'

- No default Instance is registered and cannot be automatically determined for type 'Mediachase.Commerce.Inventory.IWarehouseRepository'

The code causing this issue is:

var marketService = ServiceLocator.Current.GetInstance();

This may be because of structurmap being upgraded to >3.0. The only change of code is the below, which sounds the app.config assemblies may be not loaded in the memory.

IOC Set up// setup IoC
//ObjectFactory.Initialize(r => r.PullConfigurationFromAppConfig = true);
ObjectFactory.Initialize(); //TODO: Correct this as the upgrade is causing issue with this statement.

Any advice will be greatly appreciated?

Regards,

Ram

You should not initialize StructureMap container yourself. Instead use IConfigurableModule

Here is an example of it:

[ModuleDependency(typeof(ServiceContainerInitialization))]
[InitializableModule]
public class DependencyResolverInitialization : IConfigurableModule
{
	public void ConfigureContainer(ServiceConfigurationContext context)
	{
		context.Container.Configure(ConfigureContainer);

		// This will setup the DependencyResolver with the EPiServer StructureMap Container
		DependencyResolver.SetResolver(new StructureMapDependencyResolver(context.Container));
	}

	private static void ConfigureContainer(ConfigurationExpression container)
	{
		container.AddRegistry<StructureMapRegistry>();
	}

	public void Initialize(InitializationEngine context)
	{
	}

	public void Uninitialize(InitializationEngine context)
	{
	}
}

Hi,

You should not get those errors - what would you get if you call ServiceLocator.Current.GetInstance<ICurrentMarket>(); in your code?

Do you have custom implementation of IMarketService or IWarehouseRepository?

Hi Guys,

Thanks for your response.

But i some how feel the issue has occured after the flag "PullConfigurationFromAppConfig" was taken off from ObjectFactory initialisation, as it has become obselete after StructureMap was upgraded.

In simple terms, I would like to initialize structure map from assemblies from the config like in the older version of structure map. Is this possible or do i have to manually include all assemblies?

Maris in reading, if I want to use IConfigurableModule, will it automatically scan all the assemblies or do I have to manually include them?

Please point me to the right direction. Your time is very much appreciated.

Regards,

R

If you have this in your web.config

<episerver.framework>
<scanAssembly forceBinFolderScan="true" />
<appData basePath="appData" />
</episerver.framework>

you should be fine. Framework will scan the bin folder and do the registration needed.

http://structuremap.github.io/registration/

StructureMap no longer supports Xml configuration or MEF-style attribute configuration -- but there is some facility for rolling your own attribute-based configuration support.

It seems that XML configuration not supported anymore.

Scanning of the assemblies can be configured on the container (within StructureMap registry, for example):

Scan(x =>
            {
                x.TheCallingAssembly();
                x.WithDefaultConventions();
            });

Here it scans calling assembly, but other methods available too:

http://structuremap.github.io/registration/auto-registration-and-conventions/

Also do not use ObjectFactory directly - it might not configure same instance of container as EPiServer. You should use configuration module I mentioned before.

<p>Hi Quan,</p> <p>My application is a windows service (this service picks up feed files and update database with products and variants) not a web application so no web.config (app.config exists). Tried adding your sugestion in the config and it did not like it.</p> <p>There should be a simple way to initialize either the object factory or container to scan all the assemblies. My structure map version is 3.16 by the way as episerver libraries won't let me upgrade to 4 because of depencencies.</p> <p>Maris in reading, the&nbsp;IConfigurableModule you mentioned, will it work in 3.16? If so can you please provide the using namespaces? as mine is not resolving.</p> <p>Thanks again guys,</p> <p>R</p>

<p>IConfigurableModule is an EPiServer's interface. And it loads within EPiServer Web not windows service.</p> <p>I haven't work with windows service or command line apps within EPiServer context. I would suggest you to better use Service API to import products and variants than loading EPiServer context into windows service.</p> <p>Here is the documentation on Service API:</p> <p><a href="/documentation/Items/Episerver-Service-API/">http://world.episerver.com/documentation/Items/Episerver-Service-API/</a></p> <p>Your windows service can use this Service API to do importing instead.</p>

Hi,

You can have something like this 

ObjectFactory.Initialize(init =>
{
init.Scan(t =>
{
t.AssembliesFromPath(@"<path-to-your-folder>"); 
t.Convention();
});
});

You can also have use a static method on a static class to override the dependencies configuration
 internal static class CatalogImportInitialization
    {
        public static void InitializeServiceLocator()
        {
            var container = new Container();
            var locator = new StructureMapServiceLocator(container);
            var context = new ServiceConfigurationContext(HostType.Installer, container);

            context.Container.Configure(ce =>
            {
                ce.For<IMarketService>().Singleton().Use<MarketServiceDatabase>();
            });

            ServiceLocator.SetLocator(locator);
        }
    }

Also, I am not able to construct the ServiceConfigurationContext with both Services and Container, as the constructor accepts only either of the two, but both options fail with null reference exception of missing either Container or Services.

var context = new ServiceConfigurationContext(HostType.Installer, services);

Or

var context = new ServiceConfigurationContext(HostType.Installer, Container);

Thanks,
R

Is the windows service on the same server as the website as techically you will need a license for server if it is not on the same server.  Also you will run into issues trying to run in this configuration.  Every time you upgrade you will face issues.  I would have the windows service call the service api to do updates or create your own api controllers that the service call call. Please see this thread for others attempting to initialize.

<p>Hi Mark,</p> <p>Thanks for your reply. The service I was talking about has seperate license, just to let you know it is a legacy system working A OK for the past few years. That being said, I have clearly defined, the issue is with the upgrade of the structure map and setting up the IOC. This service is being re written which will go to production in a month. This is purely a BAU to maintain the old system.</p> <p>Quan in reading, based on my previous reply is there a way where I can set both the services and container when initialising the&nbsp;ServiceConfigurationContext?</p> <p>Technically something like this:</p> <pre class="brush:csharp;auto-links:false;toolbar:false" contenteditable="false">var context = new ServiceConfigurationContext(HostType.Installer, services, container);</pre> <p>Thanks,</p> <p>Ram</p>

Hi All,

I some how managed to sort the issue, thanks to Quan from episerver. The following code has kept me moving forward on the structuremap issue.

I hope this could be useful to someone.

            var container = new Container(config =>
            {
                config.Scan(scan =>
                {
                    scan.TheCallingAssembly();
                    scan.WithDefaultConventions();
                });
            });

            var locator = new StructureMapServiceLocator(container);
            var context = new ServiceConfigurationContext(HostType.Service, container);
            EventContext eventContext = (EventContext)typeof(EventContext).GetConstructor(BindingFlags.NonPublic | BindingFlags.Instance, null, Type.EmptyTypes, null).Invoke(null);

            context.Container.Configure(ce =>
            {
                ce.For<IMarketService>().Use<MarketServiceDatabase>();
                ce.For<IMarket>().Use<MarketImpl>();
                ce.For<ICurrentMarket>().Use<CurrentMarketImpl>();
                ce.For<ISynchronizedObjectInstanceCache>().Use<RemoteCacheSynchronization>();
                ce.For<IObjectInstanceCache>().Use<HttpRuntimeCache>();
                ce.For<ITypeScannerLookup>().Use<FakeTypeScannerLookup>();
                ce.For<IWarehouseRepository>().Singleton().Use<WarehouseRepositoryDatabase>();
                ce.For<ISynchronizedObjectInstanceCache>().Singleton().Use<FakeInstanceObjectCache>();
                ce.For<IPriceService>().Singleton().Use<PriceServiceDatabase>();
                ce.For<IPriceDetailService>().Use<PriceDetailDatabase>();
                ce.For<IWarehouseInventoryService>().Singleton().Use<WarehouseInventoryProxy>();
                ce.For<IInventoryService>().Singleton().Use<InventoryServiceProvider>();
                ce.For<IApplicationContext>().Singleton().Use<ApplicationContext>();
                ce.For<CatalogConfiguration>().Use(CatalogConfiguration.Instance);
                ce.For<IRequiredMetaFieldCollection>().Singleton().Use<DefaultRequiredMetaFields>();
                ce.For<MetaDataContext>().Singleton().Use(() => CatalogContext.MetaDataContext);
                ce.For<EventContext>().HybridHttpOrThreadLocalScoped().Use(eventContext);
                ce.For<FrameworkContext>().Use(() => FrameworkContext.Current);
                ce.For<CatalogConfiguration>().Use(CatalogConfiguration.Instance);
                ce.For<SqlContext>().Use(() => new SqlContext(BusinessFoundationConfigurationSection.Instance.Connection.Database));
                ce.For<IChangeNotificationQueueFactory>().Singleton().Use<CommerceChangeQueueFactory>();
                ce.For<IChangeNotificationManager>().Singleton().Use<ChangeNotificationManager>();
                ce.For<ICatalogSystem>().Singleton().Use(() => CatalogContext.Current);
            });

            ServiceLocator.SetLocator(locator);

Thanks once again Quan.
