Use CRM 2011 web service in Silverlight 5

In the silverlight application add CRM 2011 webservice as Service Reference.

The CRM 2011 organization url will be like below.

http://CRMServer/OrgName/XRMServices/2011/Organization.svc?wsdl

Include the Service reference name in the class where we create the helper methods to get the Iorganizationservice object.

Use below helper methods in the class to your project.

internal static class SilverlightUtility

{

   public static IOrganizationService GetSoapService()

   {

    Uri serviceUrl = CombineUrl(GetServerBaseUrl(),"/XRMServices/2011/Organization.svc/web");

     BasicHttpBinding binding = new BasicHttpBinding(Uri.UriSchemeHttps == serviceUrl.Scheme

     ? BasicHttpSecurityMode.Transport : BasicHttpSecurityMode.TransportCredentialOnly);

            binding.MaxReceivedMessageSize = int.MaxValue;

            binding.MaxBufferSize = int.MaxValue;

            binding.SendTimeout = TimeSpan.FromMinutes(2);

    return new CrmSdk.OrganizationServiceClient(binding, new EndpointAddress(serviceUrl));

 }

 public static Uri GetServerBaseUrl()

 {

   string serverUrl = (string)GetContext().Invoke("getServerUrl");

  //Remove the trailing forwards slash returned by CRM Online

  //So that it is always consistent with CRM On Premises

  if (serverUrl.EndsWith("/"))serverUrl = serverUrl.Substring(0, serverUrl.Length - 1);

  return new Uri(serverUrl);

 }

 public static Uri CombineUrl(Uri baseValue, string value)

 {

    if (null == baseValue)

    {

      throw new ArgumentNullException("baseValue");

    }

    else if (string.IsNullOrEmpty(value))

    {

      return baseValue;

    }

    //Ensure that a double '/' is not being added

    string newValue = baseValue.AbsoluteUri;

    if (!newValue.EndsWith("/", StringComparison.Ordinal))

    {

      //Check if there is a character at the beginning of value

      if (!value.StartsWith("/", StringComparison.Ordinal))

      {

         newValue += "/";

      }

    }

    else if (value.StartsWith("/", StringComparison.Ordinal))

    {

      value = value.Substring(1);

    }

    //Create the combined URL

    return new Uri(newValue + value);

 }

 #region Private Methods

 private static ScriptObject GetContext()

 {

   ScriptObject xrmProperty = (ScriptObject)HtmlPage.Window.GetProperty("Xrm");

   if (null == xrmProperty)

   {

    //It may be that the global context should be used

     try

     {

       ScriptObject globalContext = (ScriptObject)HtmlPage.Window.Invoke("GetGlobalContext");

       return globalContext;

     }

     catch (System.InvalidOperationException)

   {

     throw new InvalidOperationException("Property \"Xrm.Page.context\" is null");

   }

   return contextProperty;

 }

}

 Now you can access the GetSoapService method to get the IOrganization method.

IOrganizationService service = SilverlightUtility.GetSoapService();

CRM 2011 Plugin get secure and unsecure config information

In Crm 2011 plugin when we register the plugin we can give secure and unsecure config informations.

When the plugin fires we can receive config informations automatically in the plugin constructor method which should be 2 parameters constructor.

Here you can see my PluginTest class has one constructior which will called by CRM automatically.

 public class PluginTest : IPlugin

 {

   public PluginTest(string unsecureConfig, string secureConfig)

   {
       XmlDocument doc = new XmlDocument();
       doc.LoadXml(unsecureConfig);
   }
}

Consuming a WCF from JavaScript

This is just to give simple steps to call a WCF from client side.

1) Browse the web service URL. Then you know your web service is available. You will see a page like below one.

2) Now click relevant link in the page. Search for SOAPAction tag relevant to method you wish to use, So that you know the SOAPAction value.

3) Now get the request SOAP envelops.

a) If you have the code of WCF service run the code in Visial Studio that results a pop up of WCF Test Client. Then double click the method you need and pass some values to parameters shown in Formatted tab. Then click the XML tab to grab the Request SOAP envelop. Just omit the Header Tag from the XML you get here.

b) If the web service is provided by some other party, you can simply request the soap envelops.

4) Now we got everything we need, call the relevant method of the Web Service through below code. xmlHttp.ResponseXML will return the result.

        xmlhttp = new XMLHttpRequest();
        xmlhttp.open('POST', 'http://localhost:5555/ISV/PricingWCF/WcfIntermediateService.Service1.svc', false);
        xmlhttp.setRequestHeader('Content-Type', 'text/xml; charset=utf-8');
        xmlhttp.setRequestHeader('SOAPAction', 'http://tempuri.org/IService1/GetSalesRate');

        var data = '';
        data += '<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">';
        data += '<s:Body>';
        data += '<GetSalesRate xmlns="http://tempuri.org/">';
        data += '<productcode>AEC0023678</productcode>';
        data += '</GetSalesRate>';
        data += '</s:Body>';
        data += '</s:Envelope>';

        xmlhttp.send(data);

How to call External WCF Service within CRM 2011 Plugins

Step 1: Build and Publish the WCF Service

Step 2: Deploy the WCF Service

Step 3: Create WCF client

Create a WCF client using  ServiceModel Metadata Utility Tool (Svcutil.exe) by using following steps:

On the Start menu click All Programs, and then click Visual Studio 2010. Click Visual Studio Tools and then click Visual Studio 2010 Command Prompt.

Navigate to the directory where you want to place the client code.

Use the command-line tool ServiceModel Metadata Utility Tool (Svcutil.exe) with the appropriate switches to create the client code. The following example generates a code file and a configuration file for the service.

svcutil.exe /language:cs /out:TaxServiceClient.cs http://192.168.124.26:81/TaxProductionService

Step 4: Write Plugin to consume external WCF Service

Add the above generated .CS class into the plugin solution. In Visual Studio, right-click the client project in Solution Explorer and select Add and then Existing Item. Select the TaxServiceClient.cs file generated in the preceding step.
Open the plugin.cs class from the solution. And call the WCF client using channel factory.

#region Calling WCF Service

BasicHttpBinding myBinding = new BasicHttpBinding();myBinding.Name = “BasicHttpBinding_IPOCService”;myBinding.Security.Mode = BasicHttpSecurityMode.None;myBinding.Security.Transport.ClientCredentialType = HttpClientCredentialType.None;myBinding.Security.Transport.ProxyCredentialType = HttpProxyCredentialType.None;myBinding.Security.Message.ClientCredentialType = BasicHttpMessageCredentialType.UserName;EndpointAddress endPointAddress = new EndpointAddress(“http://192.168.124.26:81/TaxProductionService.svc“);ChannelFactory<IPOCService> factory = new ChannelFactory<IPOCService>(myBinding, endPointAddress);IPOCService channel = factory.CreateChannel();taxAmount = channel.GetCalculatedTaxValue(unitPrice);factory.Close();

#endregion

Step 5: Register the Plugin using registration tool.
