Syntax

Visual Basic
C#

'Declaration
 
Public Overloads Shared Function AsLive(Of T As Class)( _
   ByVal pocoCollection As System.Collections.Generic.ICollection(Of T), _
   ByVal scope As EntityClientScope _
) As View(Of T)

public static View<T> AsLive<T>( 
   System.Collections.Generic.ICollection<T> pocoCollection,
   EntityClientScope scope
)
where T: class

Parameters

pocoCollection: The entity collection to convert. It must be of type System.Data.Entity.Core.Objects.DataClasses.EntityCollection`1.
scope: The EntityClientScope to which the entity owning this collection belongs (in which it was fetched by a query or created).

Type Parameters

T: The type of the entities in the pocoCollection.

Return Value

The resulting live view.

Exceptions

Exception	Description
System.ArgumentException	The pocoCollection is not of type System.Data.Entity.Core.Objects.DataClasses.EntityCollection`1.

Remarks

When POCO objects are used (with proxies), navigation collection properties are typed as System.Collections.Generic.ICollection`1, not System.Data.Entity.Core.Objects.DataClasses.EntityCollection`1 (although they are System.Data.Entity.Core.Objects.DataClasses.EntityCollection`1 at run time). That is why a special AsLive extension method must be used.
