Silverlight 2.0 Application Development with LINQ to SQL and a WCF Service - Troubleshooting configurations: continued

(Page 6 of 6 )

These troubleshooting configurations are continued from the previous section.

Silverlight application configurations:

• Configure the Silverlight application (DemoSL.Web) to the same IIS root as the WCF service discussed above (and also with the same options). This is just to minimize errors during development. However, it could be totally different during deployment.

• Make sure that MIME types are added as shown below

• Make sure that you add “Service reference” to the WCF project in the current solution for better debugging capabilities.

• Make sure that “ClientAccessPolicy.xml” is added to IIS root (usually, c:inetpubwwwroot) as follows:

<?xml version="1.0" encoding="utf-8" ?>

<access-policy>

<cross-domain-access>

<policy>

<allow-from http-request-headers="*">

<domain uri="*" />

</allow-from>

<grant-to>

<resource include-subpaths="true" path="/" />

</grant-to>

</policy>

</cross-domain-access>

</access-policy>

• Make sure that “ServiceReferences.ClientConfig” is provided as shown below:

<configuration>

<system.serviceModel>

<bindings>

<basicHttpBinding>

<binding name="BasicHttpBinding_IEmpService" maxBufferSize="65536"

maxReceivedMessageSize="65536">

<security mode="None" />

</binding>

<binding name="BasicHttpBinding_IEmpService1" maxBufferSize="65536"

maxReceivedMessageSize="65536">

<security mode="None" />

</binding>

<binding name="BasicHttpBinding_IEmpService2" maxBufferSize="2147483647"

maxReceivedMessageSize="2147483647">

<security mode="None" />

</binding>

</basicHttpBinding>

</bindings>

<client>

<endpoint address="http://localhost/DemoEmpService/EmpService.svc"

binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IEmpService"

contract="DemoSL.EmpService.IEmpService" name="BasicHttpBinding_IEmpService" />

<endpoint address="http://vwin2k3/DemoEmpService/EmpService.svc"

binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IEmpService2"

contract="EmpService.IEmpService" name="BasicHttpBinding_IEmpService1" />

</client>

</system.serviceModel>

</configuration>

• “vwin2k3” is my machine name. You need to replace to yours.

• Make sure that the debug is set to true in web.config (in DemoSl.Web)
