CBR (BizTalk Server Sample)

The CBR sample demonstrates using the ExplorerOM administrative objects to add and configure new send ports for content-based routing of BizTalk messages.

Prerequisites

This sample requires that the CBRSample be deployed by running setup.bat located in the <Samples Path>\Messaging\CBRSample directory.
You must have BizTalk Server administrative privileges to use the administrative objects in this sample.
The Windows PowerShell script example requires the Windows PowerShell execution policy to allow script execution. For more information, see about_Execution_Policies.

What This Sample Does

This sample demonstrates using the administrative objects in the Microsoft.BizTalk.ExplorerOM namespace to add two new ports to the CBRApplication sample. These new ports are example ports for CBRApplication. The ports are configured to route messages to a hypothetical HTTP Web service address by using the HTTP adapter. The sample demonstrates the following operations using the ExplorerOM objects:

Using the AddNewSendPort method of the Application class to add a new send port called SendportUSOrders to CBRApplication. The port is configured to use the HTTP adapter for transport with a hypothetical Web address.
Adding a filter to SendportUSOrders that subscribes to messages in CBRApplication with the U.S. Country Code value of 100.
Adding the CBRApplication map for transforming U.S.-based messages to the outbound maps for SendportUSOrders.
Adding a new send port called SendportCANOrders to CBRApplication and configuring it to use the HTTP adapter for transport with a hypothetical Web address.
Adding a filter to SendportCANOrders that subscribes to messages in CBRApplication with the Canada Country Code value of 200.
Adding the CBRApplication map for transforming Canadian-based messages to the outbound maps for SendportCANOrders.

Where To Find This Sample

The sample is located in the following SDK location:

<Samples Path>\Admin\ExplorerOM\CBR

The following table shows the files in this sample and describes their purpose.

File(s)	Description
ContentBasedRouting.cs	Visual C# source file for operations demonstrated in this sample.
CBR.sln, CBR.csproj, CBR.suo	Solution and project files for the sample.

Building and Running This Sample

To build this sample

Make sure you have completed the steps for building, deploying, and configuring the CBRSample. Those steps are provided in CBRSample (BizTalk Server Sample).
In Visual Studio, open the solution file CBR.sln.
On the Build menu, click Build Solution.

To run this sample

Open the BizTalk Server Administration console and navigate to the CBRApplication node.
Expand the CBRApplication node to verify that the Send Ports node currently has only two ports listed as CBRUSSendPort and CBRCANSendPort.
Open a command window and navigate to the following folder:

<Samples Path>\Admin\ExplorerOM\CBR\bin\Debug
Run the file CBR.exe.
Press F5 in the BizTalk Server Administration console to refresh the view under the Send Ports node. You should now see the two new ports added to CBRApplication by this sample. They are called SendportUSOrders and SendportCANOrders.

Windows PowerShell Script Example

The following Windows PowerShell script can be used to demonstrate the same features of the ExplorerOM classes. However, because the Add method for the SendPort.OutboundTranforms collection is marked Internal in the ExplorerOM assembly it cannot be called directly from Windows PowerShell. This Windows PowerShell script demonstrates using the BizTalk WMI Provider from Windows PowerShell to add the outbound transform map to the new port.

Caution

This example or guidance references sensitive information, such as a connection string or a username and password. Never hardcode these values in your code, and make sure that you protect confidential data by using the most secure authentication available. For more information, see the following documentation:

Here is an example output from running the Windows PowerShell script to create the two new ports. The new ports can also be verified in the BizTalk Server Administration console as mentioned above.
