Exchange Server 2010 not generating ExchangeServiceBinding proxy class in Visual studio 2010 RRS feed

  • Question

  • Hi Guys,

    Presently I am working on application that needs to fetch data from Exchange server 2010. If I add Service reference in Visual studio 2010 using url  https://myServer/ews/exchange.asmx, the service reference is not generating "ExchangeServiceBinding" class. How to proceed with this? And since I am doing this in windows 8 metro and Wp7, I am not able to use managed api dll. Please help me guys.

  • It should show. There is no reason it's not if you're adding web reference correctly.

    How about trying to browse web service https://myServer/ews/exchange.asmx thru IE? Are you able to and will you see all operations?

  • I browsed  web service https://myServer/ews/exchange.asmx it has generated 

    <wsdl:binding name="ExchangeServiceBinding" type="tns:ExchangeServicePortType">
    <wsi:Claim xmlns:wsi="http://ws-i.org/schemas/conformanceClaim/" conformsTo="http://ws-i.org/profiles/basic/1.0"/>

    <soap:binding transport="http://schemas.xmlsoap.org/soap/http" style="document"/>

    But I am not able to use in C# classes. Its always an redmark below When you write ExchangeServiceBinding.

  • did you use the namespace correctly?

  • Yes, But we can only use ExchangeServicePortTypeClient object. And I also found this article http://social.msdn.microsoft.com/Forums/en-US/exchangesvrdevelopment/thread/1a312bdd-022d-4ee8-803b-082da6528d4d/.

  • In your original post you say you added it as a Service Reference ? you need to add this as a Web Reference as EWS isn't a WCF service there is a step by step example at http://msdn.microsoft.com/en-us/library/exchange/bb408520(v=exchg.140).aspx which shows how you can get to the Add Web Reference via the Advanced button.

  • There is no Add webreference via the Advanced button in windows 8 metro or wp7 projects?

  • If this is new project, why not use EWS Managed API 2.0?

  • You possibly need to right click on your service reference and update.

    I know i have done this in one  of my projects, it has worked for me, it should work for you.

  • Okay sorry afaik on Windows Phone 7 and Metro you can't use Proxy Objects from a asmx web service http://social.msdn.microsoft.com/Forums/en-US/winappswithcsharp/thread/59fa422b-5604-48d9-a63f-04b404d5cc3a only WCF is supported. So you need to use Raw soap for communicating with EWS on these platforms.
