Using Silverlight Init parameters to get the WCF Service url dynamically

http://www.c-sharpcorner.com/UploadFile/dpatra/InitParamsInSilverlight06302009024633AM/InitParamsInSilverlight.aspx

http://msdn.microsoft.com/en-us/library/cc189004(v=VS.95).aspx

Step 1 :
Configure the WCF Service URL at web.config file

   1:  <configuration>

   2:    <appSettings>

   3:      <add key="myWCFServiceUrl" value="http://SomeServer:55460/myWCFService.svc" />

   4:    </appSettings>

   5:  </configuration>

Step 2 :
Supply the configured URL as a initparameters Silverlight

   1:  <form id="form1" runat="server" style="height:100%">

   2:      <div id="silverlightControlHost">

   3:          <object data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%">

   4:                <param name="InitParams" value='myWCFServiceUrlParameter= <% =ConfigurationManager.AppSettings["myWCFServiceUrl"].ToString()%> '/>

   5:            <param name="source" value="ClientBin/mySilverlight.xap"/>

   6:                <param name="onError" value="onSilverlightError" />

   7:                <param name="background" value="white" />

   8:                <param name="minRuntimeVersion" value="4.0.50826.0" />

   9:                <param name="autoUpgrade" value="true" />

  10:                <a href="http://go.microsoft.com/fwlink/?LinkID=149156&v=4.0.50826.0" style="text-decoration:none">

  11:                     <img src="http://go.microsoft.com/fwlink/?LinkId=161376" alt="Get Microsoft Silverlight" style="border-style:none"/>

  12:                </a>

  13:            </object><iframe id="_sl_historyFrame" style="visibility:hidden;height:0px;width:0px;border:0px"></iframe></div>

  14:      </form>

Step 3 :
Modify the app.xaml.cs file to read the init parameters

   1:  public static string myWCFServiceURL = "";

   2:          public App()

   3:          {

   4:              this.Startup += this.Application_Startup;

   5:              this.Exit += this.Application_Exit;

   6:              this.UnhandledException += this.Application_UnhandledException;

7:

   8:              InitializeComponent();

   9:          }

10:

  11:          private void Application_Startup(object sender, StartupEventArgs e)

  12:          {

  13:              if (e.InitParams.ContainsKey("myWCFServiceUrlParameter") && !string.IsNullOrEmpty(e.InitParams["myWCFServiceUrlParameter"]))

  14:                  myWCFServiceURL = e.InitParams["myWCFServiceUrlParameter"];

  15:              this.RootVisual = new MainPage();

  16:          }

Step 4 :
use the URL during the WCF Client creation in Silverlight

   1:  myWCFServiceClient = new myWCFServiceClient(new BasicHttpBinding(), new EndpointAddress(App.myWCFServiceURL));

Silverlight ClientBin is not updated

Entity Framework vs LINQ to SQL

LINQ to SQL is the quick-and-easy way to do it. This means you will get going quicker, and deliver quicker if you are working on something smaller.
Entity Framework is the all-out, no-holds-barred way to do it. This means you will take more time up-front, develop slower, and have more flexibility if you are working on something larger.
