Applies to: SharePoint Server 2010

The following example shows how to import a BDC model into a farms catalog.

Prerequisites:

Microsoft SharePoint Server 2010 or Microsoft SharePoint Foundation 2010.
Microsoft .NET Framework 3.5.

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 code in Program.cs with the code listed at the end of this procedure.
Save the project.
Replace the values of strModelName and strXmlFile2Import with the name and full path of your model file, respectively.
Replace the value of strSomeSite with the URL of a site in your farm.
Compile and run the project.
Open Internet Explorer and navigate to the farm's central administration.
In the browser, click Manage service applications.
Click Business Data Connectivity Service.

Note

Business Data Connectivity Service is the default name of the BDC service. If the administrator has named the BDC service differently, a different name will appear in the Central Administration Web page.

The newly imported model is displayed.
