    Hi everyone,

    I am using Visual Studio 2010 RTM, Silverlight 4, WCF RIA Services.

    When I execute the following code, everything works fine:
    DBDomainContext db = new DBDomainContext();
    uiDataGrid.ItemsSource = db.Teams;
    db.Load(db.GetTeamsQuery(),     true);

    But when I add the Windows Azure Cloud Service project and use the existing project as a WebRole I get the following error:
    System.ServiceModel.DomainServices.Client.DomainOperationException:
    Load operation failed for query 'GetTeams'. The content type text/html; charset=utf-8 of the response message does not match the content type of the binding (application/msbin1).
    If using a custom encoder, be sure that the IsContentTypeSupport method is implemented properly.
    The first 1024 bytes of the response were:
    '<html>
      <head>
        <title>
        Could not load type 'System.ServiceModel.Activation.ServiceHttpHandlerFactory' from assembly 'System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.
        </title>
    .....'

    Hi,

    I remember I tested this scenario before and it should work without any problem. From the description itself the client expects the content HTTP header to be application/msbin1 but service sends back text/html so the exception is thrown. You may confirm this by comparing the working/non-working response to see whether there're any differences. A workaround might be using Message Inspector to change the content type. If it still doesn't work please upload a demo project that can reproduce this issue to let me test it locally. You can upload the project to http://skydrive.com and paste download link here.

    Hi,

    I'm unable to reproduce this issue with the project you provided. Could any other community members help to confirm it can be reproduced?

    I have installed a new development system. With this one everything works fine!
    I wonder what is wrong with my main development system.

    So The Copy Local propertys are set to True.

    I have no idea. What happens if you reinstall all related components on that machine? Does it work?
