C# Class GSoft.Dynamite.ServiceLocator.AddOnProvidedServiceLocator

Special service locator which scans the GAC for DLLs that match the *.ServiceLocator.dll pattern for a ISharePointServiceLocatorAccessor to which it will delegate container provider duties. Thanks to these ServiceLocator-bootstrapping mechanics, you can build reusable "framework" SharePoint components that can have their inner implementations overrided by AddOns' registration module (since the AddOn's ServiceLocator is responsible for determining the final set of all registration modules that will be loaded).

Method Description
BeginLifetimeScope ( ) : ILifetimeScope

Creates a new child lifetime scope - a child to the most-nested currently available lifetime scope. In an HTTP-request context, will return a child scope to the shared per-request scope (allowing you to inject InstancePerSite, InstancePerWeb and InstancePerRequest-registered objects). Be sure to enable Dynamite's feature HttpModule feature: "GSoft.Dynamite.SP_Web Config Modifications" so that InstancePerRequest-scoped objects get properly disposed at the end of every HttpRequest. Outside an HTTP-request context, will return the a child of the root application container itself (preventing you from injecting InstancePerSite, InstancePerWeb or InstancePerRequest objects). If more than two DLLs exist in GAC that match the *.ServiceLocator.DLL filename pattern, and access to this member is responsible for DI bootstrapping at application startup, due to lack of context it will be impossible to disambiguate between the available containers. Use BeginLifetimeScope(SPFeature) or BeginLifetimeScope(SPWeb) or BeginLifetimeScope(SPSite) or BeginLifetimeScope(SPWebApplication) instead when outside an HTTP-request context (e.g. Cmdlets, FeatureActivated, etc.). If more than 1 assembly matches the *.ServiceLocator.DLL pattern in the GAC, store your preferred ServiceLocator assembly name (with key: 'ServiceLocatorAssemblyName') in one of the SPPersistedObject's property bags in the SPWeb-SPSite-SPWebApp-SPFarm hierarchy to indicate which ServiceLocator should be used in your context. If the disambiguator setting cannot be found in any of the property bags in the hierarchy, an error will be logged to ULS and the FallbackServiceLocator will be used (preventing your AddOn registration modules from being loaded). Please dispose this lifetime scope when done (E.G. call this method from a using block).

BeginLifetimeScope ( SPFarm farm ) : ILifetimeScope

Creates a new child lifetime scope under the root application container (objects registered as InstancePerSite, InstancePerWeb or InstancePerRequest will be inaccessible). If more than 1 assembly matches the *.ServiceLocator.DLL pattern in the GAC, store your preferred ServiceLocator assembly name (with key: 'ServiceLocatorAssemblyName') in the SPFarm property bag to indicate which ServiceLocator should be used in your context. If the disambiguator setting cannot be found in any of the property bags in the hierarchy, an error will be logged to ULS and the FallbackServiceLocator will be used (preventing your AddOn registration modules from being loaded). Please dispose this lifetime scope when done (E.G. call this method from a using block).

BeginLifetimeScope ( SPFeature feature ) : ILifetimeScope

Creates a new child lifetime scope that is as nested as possible, depending on the scope of the specified feature. In a SPSite or SPWeb-scoped feature context, will return a web-specific lifetime scope (allowing you to inject InstancePerSite and InstancePerWeb objects - InstancePerRequest scoped objects will be inaccessible). In a SPFarm or SPWebApplication feature context, will return a child container of the root application container (preventing you from injecting InstancePerSite, InstancePerWeb or InstancePerRequest objects). If more than 1 assembly matches the *.ServiceLocator.DLL pattern in the GAC, store your preferred ServiceLocator assembly name (with key: 'ServiceLocatorAssemblyName') in one of the SPPersistedObject's property bags in the SPWeb-SPSite-SPWebApp-SPFarm hierarchy to indicate which ServiceLocator should be used in your context. If the disambiguator setting cannot be found in any of the property bags in the hierarchy, an error will be logged to ULS and the FallbackServiceLocator will be used (preventing your AddOn registration modules from being loaded). Please dispose this lifetime scope when done (E.G. call this method from a using block).

BeginLifetimeScope ( SPSite site ) : ILifetimeScope

Creates a new child lifetime scope under the scope of the specified site collection (allowing you to inject InstancePerSite objects - InstancePerWeb and InstancePerRequest scoped objects will be inaccessible). If more than 1 assembly matches the *.ServiceLocator.DLL pattern in the GAC, store your preferred ServiceLocator assembly name (with key: 'ServiceLocatorAssemblyName') in one of the SPPersistedObject's property bags in the SPSite-SPWebApp-SPFarm hierarchy to indicate which ServiceLocator should be used in your context. If the disambiguator setting cannot be found in any of the property bags in the hierarchy, an error will be logged to ULS and the FallbackServiceLocator will be used (preventing your AddOn registration modules from being loaded). Please dispose this lifetime scope when done (E.G. call this method from a using block).

BeginLifetimeScope ( SPWeb web ) : ILifetimeScope

Creates a new child lifetime scope under the scope of the specified web (allowing you to inject InstancePerSite and InstancePerWeb objects - InstancePerRequest scoped objects will be inaccessible). If more than 1 assembly matches the *.ServiceLocator.DLL pattern in the GAC, store your preferred ServiceLocator assembly name (with key: 'ServiceLocatorAssemblyName') in one of the SPPersistedObject's property bags in the SPWeb-SPSite-SPWebApp-SPFarm hierarchy to indicate which ServiceLocator should be used in your context. If the disambiguator setting cannot be found in any of the property bags in the hierarchy, an error will be logged to ULS and the FallbackServiceLocator will be used (preventing your AddOn registration modules from being loaded). Please dispose this lifetime scope when done (E.G. call this method from a using block).

BeginLifetimeScope ( SPWebApplication webApplication ) : ILifetimeScope

Creates a new child lifetime scope under the root application container (objects registered as InstancePerSite, InstancePerWeb or InstancePerRequest will be inaccessible). If more than 1 assembly matches the *.ServiceLocator.DLL pattern in the GAC, store your preferred ServiceLocator assembly name (with key: 'ServiceLocatorAssemblyName') in one of the SPPersistedObject's property bags in the SPWebApp-SPFarm hierarchy to indicate which ServiceLocator should be used in your context. If the disambiguator setting cannot be found in any of the property bags in the hierarchy, an error will be logged to ULS and the FallbackServiceLocator will be used (preventing your AddOn registration modules from being loaded). Please dispose this lifetime scope when done (E.G. call this method from a using block).
