EntityInstanceReference class

Represents a reference to an External Item.

System.Object
  System.MarshalByRefObject
    Microsoft.BusinessData.Runtime.EntityInstanceReference

Namespace:  Microsoft.BusinessData.Runtime
Assembly:  Microsoft.BusinessData (in Microsoft.BusinessData.dll)

public sealed class EntityInstanceReference : MarshalByRefObject

EntityInstanceReference (EIR) allows applications to create a reference to an External Item, which can be stored as a string value. The applications can use the string value to keep track of relevant External Items. For example, an application can ask the user to specify an External Item to be associated with a document, then store the EIR as a string value in the document to remember this relationship. When needed, the application can get the External Item back using the EIR. EIR can also be used to send references to External Items to other machines or processes.

NoteNote

The string representation of the EntityInstanceReference is case sensitive.

NoteNote

The EntityInstanceReference identifies the external content type by name and namespace. Therefore the reference is valid only within a group of Metadata Stores that are controlled together. For example, it is safe to send EIRs between the users of a SharePoint farm; however, it is not safe to send EIRs across the Internet.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
