Constructors

MetadataWorkspace()	Initializes a new instance of the MetadataWorkspace class.
MetadataWorkspace(Func<EdmItemCollection>, Func<StoreItemCollection>, Func<StorageMappingItemCollection>)	Constructs a MetadataWorkspace with loaders for all item collections (ItemCollection) that come from traditional EDMX mapping. Default o-space and o/c mapping collections will be used. The item collection delegates are executed lazily when a given collection is used for the first time. It is acceptable to pass a delegate that returns null if the collection will never be used, but this is rarely done, and any attempt by EF to use the collection in such cases will result in an exception.
MetadataWorkspace(Func<EdmItemCollection>, Func<StoreItemCollection>, Func<StorageMappingItemCollection>, Func<ObjectItemCollection>)	Constructs a MetadataWorkspace with loaders for all item collections (ItemCollection) needed by EF except the o/c mapping which will be created automatically based on the given o-space and c-space loaders. The item collection delegates are executed lazily when a given collection is used for the first time. It is acceptable to pass a delegate that returns null if the collection will never be used, but this is rarely done, and any attempt by EF to use the collection in such cases will result in an exception.
MetadataWorkspace(IEnumerable<String>, IEnumerable<Assembly>)	Initializes a new instance of the MetadataWorkspace class using the specified paths and assemblies.

Properties

MaximumEdmVersionSupported

The Max EDM version thats going to be supported by the runtime.
