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.

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);  
}
