AsLive<T>(ICollection<T>,EntityClientScope) Method

Converts a POCO System.Data.Entity.Core.Objects.DataClasses.EntityCollection`1 to an editable live view.

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.

Requirements

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
