zzeeshann, please start a new thread.  The error above doesn't seem to have anything to do with WCF.

Answer 4

Hello Steve,

i went through quite a few articles on WCF and AZURE but found no solution to the issue i am facing. I hope you can unblock me. The problem statement is as under:


I have a SecureFacebook.svc file in a AZURE webrole. When i set the Webrole as the start up project i get the WSDL generated (which i think is fine since im running it on localhost i.e. the URL formed is http://localhost:50892/SecureFacebook.svc?wsdl ) but when i set the AZURE deployment as teh startup project and run the application i get the url http://127.0.0.1:81/SecureFacebook.svc and on clicking svcutil.exe http://<MACHINE NAME>/securefacebook.svc?wsdl i get

The webpage cannot be found.

Any help from your end would be appreacited since i have hit  a roadblock. I have followed the steps given in this article but it did not solve the issue http://social.msdn.microsoft.com/Forums/en/windowsazure/thread/57ae928c-6c29-4e67-9fc3-d8969ca0574a/

Hi Z,
 This issue is regarding StorageClientLibrary which you are using to Access Azure Storage...
when you registered to Azure and Creates Storage Account.. It provides you Account Key,
As you are using StorageClient.StorageAccountInfo.GetAccountInfoFromConfiguration() method to access Account Key,

That Key should be added in AppSetting of your Application...

    <add key="AccountName" value="xyz" />
    <add key="AccountSharedKey" value="9a/34534545535+65675gfhgfhjhjgjghj==" />
    <add key="BlobStorageEndpoint" value="http://blob.core.windows.net" />
   <add key="TableStorageEndpoint" value="http://Table.core.windows.net" />
if you are using Cloud S ervice please mention same information in ServiceConfiguration file So that u can run your application
on Cloud and on Development fabric(with BlobStorageEndpoint as http://127.0.0.1:10000/ for locally) as well...
