Loading BAM Interceptors Using the BAM API
This topic provides information about loading the WF and WCF interceptors from your code rather than through a configuration file.
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:
Loading the WF Interceptor from Code
To load the WF interceptor runtime from your code, you must create a new instance of WorkflowRuntime and call the AddService method with a new instance of BamTrackingService. This is demonstrated below.
string connectionString = "Integrated Security=SSPI;Data Source=.;Initial Catalog=BAMPrimaryImport";
int PollingIntervalSec = 300;
WorkflowRuntime workflowRuntime = new WorkflowRuntime();
workflowRuntime.AddService(new BamTrackingService(connectionString, interceptorConfigurationPollingInterval));
Loading the WCF Interceptor from Code
To load the WCF interceptor, you must create a derived class that opens the service and is accessible to your implementation. This is demonstrated below.
// Your project must have a reference to Microsoft.BizTalk.BAM.Interceptors.dll.
// Create a derived class accessible to the implementation that opens the service.
internal class MyBamBehaviorExtension : BamBehaviorExtension
{
internal MyBamBehaviorExtension(string connectionString, int pollingInterval)
: base()
{
this.ConnectionString = connectionString;
this.PollingIntervalSec = pollingInterval.ToString();
}
internal IEndpointBehavior Create()
{
return (IEndpointBehavior) this.CreateBehavior();
}
}
// Add the endpoint behavior just before the service is opened.
// In this example the connection string and polling intervals are being read from appSettings in App.config.
MyBamBehaviorExtension bamBehaviorExtension = new MyBamBehaviorExtension(ConfigurationManager.AppSettings["ConnectionString"], int.Parse(ConfigurationManager.AppSettings["PollingIntervalSec"]));
IEndpointBehavior bamBehavior = bamBehaviorExtension.Create();
foreach (System.ServiceModel.Description.ServiceEndpoint endpoint in myServiceHost.Description.Endpoints)
{
if (endpoint.Behaviors.Find<MyBamBehaviorExtension>() == null)
endpoint.Behaviors.Add(bamBehavior);
}
