    <p>I have created a test service with a method that contains a very long loop. I was hoping that when a timeout transaction occurs, the method execution will flush, but it doesn't. The client gets a timeout, but the processing continues on the server. </p> <p>Is there way to stop it? Without changing the method code?</p> <p>Here is the example: in the example I call the method QueueRequest using queue binding, and after 10 seconds the transaction is aborted. At this point a retry occurs, causing the same issue. After a few retries the server is doing 100% cpu work trying to ran the loop on multiple threads / instances even if the message is poison and dropped.</p> <hr> <pre><code> // NOTE: If you change the class name "Service1" here, you must also update the reference to "Service1" in App.config. [ServiceBehavior(InstanceContextMode=InstanceContextMode.PerCall, TransactionTimeout="00:00:10", ReleaseServiceInstanceOnTransactionComplete=true)] [ErrorHandlingBehaviorAttribute] public class Service1 : IQueueService { public Service1() { Trace.WriteLine("Creating an instance on thread " + Thread.CurrentThread.ManagedThreadId.ToString()); } ~Service1() { Trace.WriteLine("Destroying an instance on thread " + Thread.CurrentThread.ManagedThreadId.ToString()); } [OperationBehavior(TransactionScopeRequired = true, TransactionAutoComplete = true)] public void QueueRequest(string message) { int id = Thread.CurrentThread.ManagedThreadId; Trace.WriteLine("Got Message on thread " + id.ToString()); for (int i = 0; i &lt; 1000000; i++) { Trace.WriteLine("Processing " + i.ToString() + " Thread ID " + id.ToString()); Thread.Sleep(1000); } } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
