RIA Services: A DomainService IS A WCF Service – Add Service Reference

@Evan: I didn't find a nice solution for authenticating a client, but the code below works. Basically, you call Login on the AuthenticationService, store the cookie, and send this cookie whenever you need to.

AuthenticationServiceClient context = new AuthenticationServiceClient("BasicHttpBinding_AuthenticationService");

using (OperationContextScope operationContext = new OperationContextScope(context.InnerChannel))

{

QueryResult<User> result = context.Login("testuser", "testpassword!", false, null);

// Store cookie somewhere

HttpResponseMessageProperty response = (HttpResponseMessageProperty)OperationContext.Current.IncomingMessageProperties[HttpResponseMessageProperty.Name];

sharedCookie = response.Headers["Set-Cookie"];

}

// Later

OtherServiceClient context = new OtherServiceClient("BasicHttpBinding_OtherService");

using (OperationContextScope operationContext = new OperationContextScope(context.InnerChannel))

{

// Add stored cookie

HttpRequestMessageProperty request = new HttpRequestMessageProperty();

request.Headers[HttpRequestHeader.Cookie] = sharedCookie;

OperationContext.Current.OutgoingMessageProperties[HttpRequestMessageProperty.Name] = request;

context.SomeOperationThatRequiresAuthentication();

}

How is possible to create references in ChangeSetEntries in order to submit a simple hierarchy like Report (1) -> ReportEntry (n), back to server?

Great article Brad. One quick question. When decorating the service with RequiresAuthentication, how do you authenticate a client?

Thanks,

Evan

I'm getting that problem that results in this error:

An ExceptionDetail, likely created by IncludeExceptionDetailInFaults=true, whose value is:

System.NullReferenceException: Object reference not set to an instance of an object.

at System.ServiceModel.Description.ServiceMetadataBehavior.MetadataExtensionInitializer.GenerateMetadata()

According to Google, I'm not the only one. No one has posted what they've done to solve that though. Any ideas?

Hi,

Is there a way to host a domainService in a console app or a windows service ?

I've been through all the web to find something about this topic.

thank you.

I'm also running up against the same problem as pragati. My situation requires mt tohhost the domain services in a completely seperate web site from the silverlight app. When I try to add the domain service as a service reference to the silverlight app, I get the above mentioned errors. The domain service work fine in a traditional asp page amd wcf service when added as a service reference.

Hi,

I've done the same way as per blog. But, I used the service asynchonously like -

private CustDomainService.CustDomainServiceClient objClient = new prjTestRIAservice.CustDomainService.CustDomainServiceClient("BasicHttpBinding_CustDomainService");

public MainPage()

{

InitializeComponent();

objClient.GetCustomersAsync();

objClient.GetCustomersCompleted += new EventHandler<prjTestRIAservice.CustDomainService.GetCustomersCompletedEventArgs>(objClient_GetCustomersCompleted);

}

void objClient_GetCustomersCompleted(object sender, prjTestRIAservice.CustDomainService.GetCustomersCompletedEventArgs e)

{

var lstdata = e.Result;

grdTest.ItemsSource = lstdata.RootResults;

}

*******************************************

I'm getting error like -

'prjTestRIAservice.CustDomainService.QueryResultOfCustomers' does not implement inherited abstract member 'System.Windows.Ria.Services.QueryResult.GetIncludedResults()'

and

'prjTestRIAservice.CustDomainService.QueryResultOfCustomers' does not implement inherited abstract member 'System.Windows.Ria.Services.QueryResult.GetRootResults()'
