Description

The following code example shows how to programmatically execute a BulkSpecificFinder method instance of an external content type by using the BDC Runtime object model on the server.

Prerequisites

Microsoft SharePoint Server 2010 or Microsoft SharePoint Foundation 2010 on the server.
Microsoft .NET Framework 3.5 and Microsoft Visual Studio on the client.

To use this example

Start Visual Studio and create a C# Console application project. Select .NET Framework 3.5 when you create the project.
From the View menu, click Property Pages to bring up the project properties.
In the Build tab, for the Platform target, select Any CPU.
Close the project properties window.
In Solution Explorer, under References, remove all project references except for System and System.Core.
Add the following references to the project:
1. Microsoft.BusinessData
2. Microsoft.SharePoint
3. System.Web
Replace the autogenerated code in Program.cs with the code listed at the end of this procedure.
Replace the <ID> values and the SiteURL value with valid values.
This sample is based on the AdventureWorks sample database and the SalesOrder external content type. If your external system is different, change the name of the external content type and LobSystem as appropriate in the code.
Save the project.
Compile and run the project.
