    LobSystemInstance lobSystemInstance
)

Parameters

• methodInstanceToExecute
  Type: Microsoft.Office.Server.ApplicationRegistry.MetadataModel.MethodInstance

  The MethodInstance object that represents the logic in the backend that we want to execute on this entity instance.

• lobSystemInstance
  Type: Microsoft.Office.Server.ApplicationRegistry.MetadataModel.LobSystemInstance

  The LobSystemInstance object that this entity instance was created from.

Return Value

Type: System.Object
An object that represents the entity instances returned when the back-end method is invoked.

Implements

IInstance.Execute(MethodInstance, LobSystemInstance)
IInstance.Execute(MethodInstance, LobSystemInstance)

Remarks

There are two places in the Business Data Catalog where you can execute code in a backend system: on the Entity, and on the instance of an Entity. These two methods of execution correspond to static and instance methods in C# or other object oriented programming languages. Calling .Execute on an Entity essentially requires the user to pass in parameters that mirror the underlying backend API. Calling .Execute on an instance of an Entity causes the Business Data Catalog to automatically plumb the value of the identifiers of the instance of the Entity into the appropriate slots in the backend API, eliminating the need for the end user to provide that information or set up those parameters.
