    <p>today i have a question regarding style of WCF communication.</p> <p>I sometimes refuse a bit so use things programmatically (want to have control myself) and I don't like huge. Sometimes communication between 2 program parts are needed, sometimes on the same machine, sometimes on network.</p> <p>So I tried to use WCF programmatically instead of using configuration files, svcutil and so on.</p> <p>If I use the following:</p> <p>a) Define a contract</p> <pre><code>[ServiceContract] public interface IMyContract { [OperationContract] bool DoSomething(string something_in); } </code></pre> <p>b) programm some code</p> <pre><code>public class MySomething: IMyContract { public bool DoSomething(string something_in) { if(String.IsNullOrEmpty(something_in) return false; return true; } } </code></pre> <p>and then programmaticly host it</p> <pre><code>Uri baseAddress = new Uri("net.tcp://localhost:48080/MySimpleService"); using (ServiceHost host = new ServiceHost(typeof(MyContract), baseAddress)) { host.AddServiceEndpoint(typeof(IMyContract), new NetTcpBinding(), ""); host.Open(); Console.WriteLine("&lt;Enter&gt; to stop the service."); Console.ReadLine(); host.Close(); </code></pre> <p>and later just consume it from another program:</p> <pre><code>var binding = new NetTcpBinding(); var endpoint = new EndpointAddress("net.tcp://localhost:48080/MySimpleService"); var channelFactory = new ChannelFactory&lt;IMyContract&gt;(binding, endpoint); IMyContract client = null; try { client = channelFactory.CreateChannel(); bool test = client.DoSomething(); ((ICommunicationObject)client).Close(); } catch (Exception ex) { if (client != null) { ((ICommunicationObject)client).Abort(); } } </code></pre> <p>what would be the drawback?</p> <p>Wouldn't it be easier to understand?</p> <p>Could such a thing cause other problems?</p> <p>(I'm mostly interested in this, because I think it is quite annoying to use svcutil and so one just because of a class change, which can simple handled manually, if the wcf service is only used for cumminication of own programs) So what am I missing?</p> <p>Is it just a bad style to do things manually instead with large unread XML files?</p>

    1. COIf it's for your own consumption and doesn't require external network hosts/addresses then I don't see a problem. If you want to redistribute to 3rd parties/different machines with the service available over a network, separate config might be desirable.

    2. COI think your apporach is just fine. It depends on how often you think that the endpoint addresses and bindings might change etc. If it does so often and you have to recomplie and publish a new program every time they change this may be a hassle...

    3. COone thing comes in mind. you can change configuration without recompiling the code.

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.
