Overloads

MetadataWorkspace()	Initializes a new instance of the MetadataWorkspace class.
MetadataWorkspace(IEnumerable<String>, IEnumerable<Assembly>)	Initializes a new instance of the MetadataWorkspace class using the specified paths and assemblies.
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()

Initializes a new instance of the MetadataWorkspace class.

public MetadataWorkspace ();

Public Sub New ()

Applies to

MetadataWorkspace(IEnumerable<String>, IEnumerable<Assembly>)

Initializes a new instance of the MetadataWorkspace class using the specified paths and assemblies.

Applies to

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.

Public Sub New (cSpaceLoader As Func(Of EdmItemCollection), sSpaceLoader As Func(Of StoreItemCollection), csMappingLoader As Func(Of StorageMappingItemCollection))

Parameters

cSpaceLoader: Func<EdmItemCollection>

Delegate to return the c-space (CSDL) item collection.

sSpaceLoader: Func<StoreItemCollection>

Delegate to return the s-space (SSDL) item collection.

csMappingLoader: Func<StorageMappingItemCollection>

Delegate to return the c/s mapping (MSL) item collection.
