    <p>I have been trying to implement the transaction flow in WCF. When I am executing My Client code I could see that the transaction is propagating to the Service from client as I see the record is locked in db(I used with(nolock) in SQL server to see if the transaction is happening). However my client code completes successfully, but the transaction is rolled back, Do I miss something here, </p> <p>following are the code snippets,</p> <p>Service class</p> <pre><code>[ServiceBehavior( TransactionIsolationLevel = System.Transactions.IsolationLevel.ReadCommitted, TransactionTimeout = "00:00:30")] public class TransactionTest : ITransactionTest { [OperationBehavior(TransactionScopeRequired = true, TransactionAutoComplete = false)] public void DoWork(string aliasName) { string constr = "Data Source=MyDBServer;User ID=DBUser;password=123;Initial Catalog=MyTestDB;"; using (SqlConnection objcon = new SqlConnection(constr)) { string qry = @"UPDATE Customer SET Alias = '" + aliasName + "' WHERE CustomerID = 10"; SqlCommand cmd = new SqlCommand(qry, objcon); objcon.Open(); cmd.ExecuteNonQuery(); } } </code></pre> <p>}</p> <pre><code> Service Contract: [ServiceContract(SessionMode = SessionMode.Required)] public interface ITransactionTest { [OperationContract, TransactionFlow(TransactionFlowOption.Allowed)] void DoWork(string aliasName); } </code></pre> <p>following is my Web.config</p> <pre><code>&lt;bindings&gt; &lt;wsHttpBinding&gt; &lt;binding name="wsHttpBinding_ITransactionTest" transactionFlow="true"/&gt; &lt;/wsHttpBinding&gt; &lt;/bindings&gt; </code></pre> <p>I have added a service reference in my client application (which is a console application)</p> <pre><code>class Program { static void Main(string[] args) { //updateCustomeAlias(); try { using (TransactionScope TranScope = new TransactionScope(TransactionScopeOption.RequiresNew)) { var proxy = new TransactionTestClient("WSHttpBinding_ITransactionTest"); proxy.DoWork("XYZ"); TranScope.Complete(); } } catch { //Exception handling. } } </code></pre> <p>Client application config </p> <pre><code> &lt;system.serviceModel&gt; &lt;bindings&gt; &lt;wsHttpBinding&gt; &lt;binding name="WSHttpBinding_ITransactionTest" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" bypassProxyOnLocal="false" transactionFlow="false" hostNameComparisonMode="StrongWildcard" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true" allowCookies="false"&gt; &lt;readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /&gt; &lt;reliableSession ordered="true" inactivityTimeout="00:10:00" enabled="false" /&gt; &lt;security mode="Message"&gt; &lt;transport clientCredentialType="Windows" proxyCredentialType="None" realm="" /&gt; &lt;message clientCredentialType="Windows" negotiateServiceCredential="true" algorithmSuite="Default" /&gt; &lt;/security&gt; &lt;/binding&gt; &lt;/wsHttpBinding&gt; &lt;/bindings&gt; &lt;client&gt; &lt;endpoint address="http://localhost:91/TransactionTest.svc" binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_ITransactionTest" contract="TransactionTestService.ITransactionTest" name="WSHttpBinding_ITransactionTest"&gt; &lt;/endpoint&gt; &lt;/client&gt; &lt;/system.serviceModel&gt; </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.
