    <p>My first few attempts at creating a self hosted service. Trying to make something up which will accept a query string and return some text but have have a few issues:</p> <ul> <li><p>All the documentation talks about endpoints being created automatically for each base address if they are not found in a config file. This doesn't seem to be the case for me, I get the "Service has zero application endpoints..." exception. Manually specifying a base endpoint as below seems to resolve this:</p> <pre><code>using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.ServiceModel; using System.ServiceModel.Description; namespace TestService { [ServiceContract] public interface IHelloWorldService { [OperationContract] string SayHello(string name); } public class HelloWorldService : IHelloWorldService { public string SayHello(string name) { return string.Format("Hello, {0}", name); } } class Program { static void Main(string[] args) { string baseaddr = "http://localhost:8080/HelloWorldService/"; Uri baseAddress = new Uri(baseaddr); // Create the ServiceHost. using (ServiceHost host = new ServiceHost(typeof(HelloWorldService), baseAddress)) { // Enable metadata publishing. ServiceMetadataBehavior smb = new ServiceMetadataBehavior(); smb.HttpGetEnabled = true; smb.MetadataExporter.PolicyVersion = PolicyVersion.Policy15; host.Description.Behaviors.Add(smb); host.AddServiceEndpoint(typeof(IHelloWorldService), new BasicHttpBinding(), baseaddr); host.AddServiceEndpoint(typeof(IHelloWorldService), new BasicHttpBinding(), baseaddr + "SayHello"); //for some reason a default endpoint does not get created here host.Open(); Console.WriteLine("The service is ready at {0}", baseAddress); Console.WriteLine("Press &lt;Enter&gt; to stop the service."); Console.ReadLine(); // Close the ServiceHost. host.Close(); } } } } </code></pre></li> <li><p>How would I go about setting this up to return the value of name in SayHello(string name) when requested thusly: localhost:8080/HelloWorldService/SayHello?name=kyle</p></li> </ul> <p>I'm trying to walk before running, but this just seems like crawling...</p>

    1. COAre you using .NET 3.5 or .NET 4 ?? The "create default endpoints for base address" feature is a new thing in .NET 4 - won't work in 3.5

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.
