I'm having a problem implementing this. I have a working

DesignDataService : LinqToEntitiesDomainService<DesignRepositoryEntities>

that I can hit from my Silverlight application.

I'm attempting to add a Domain ADO.NET Data Service class:

WebDataService1: DataService<DesignDataService>, IServiceProvider

However, inside the call to GetService() when the serviceType parameter is of type {System.Data.Services.Providers.IDataServiceProvider}, I get a MissingManifestResourceException at the call to this.provider.GetService(serviceType):

Could not find any resources appropriate for the specified culture or the neutral culture. Make sure \"System.Data.Services.Providers.DomainService.resources\" was correctly embedded or linked into assembly \"System.Data.Services.Providers.DomainService\" at compile time, or that all the satellite assemblies required are loadable and fully signed.

Any clues? All of my RIA assembly references are marked with "copy local". My web app's "bin" folder does not have any language specific subfolders.

Just noticed a gotcha when trying to put together this project myself. Be sure to include the correct version of the System.Data.Services dll from the path "C:\Program Files\Microsoft SDKs\RIA Services\v1.0\Libraries\Server\System.Data.Services.dll".

You need to use the RIA Services version of the DLL or your call to your domain service will return no entities :

<atom:title>Default</atom:title>

</workspace>

</service>

Once we have our data showing in the Domain ADO.Net Data service (in the view browser), how do we hook this up to RIA. I tried adding a Domain Service Class and the Available DataContexts/ObjectContexts only has the empty domain service class to select from. The Domain ADO Data service does not show up.. I might be missing something but i figured it would show up here.

GusG - I think you need to edit the service to say what entities to expose... You can use "*" for all if you'd like..

Brad,

Why is that when I created a plain Web App using ADO.Net Data Services template and a Domain Service as data source for the Data Service it does not expose any data?

thanks for your interest.

since I really only have much of a shell I am going to start over and regenerate everything again,

Mabey I did something i shouldn't have.

When I get there I will try to insert the WebDataService and see what happens.

If my problem continues I will let you know.

thanks again

Sorry, one more thing.

The Silverlight Application, what liittle i have done, is able to connect to the data.

There are 16 Entities in the model.

The KerdaService was generated with all 16 Entities.

Each Entity has the standard Get,Insert,Update, Delete in the Service:

public IQueryable<Vendor> GetVendor()

{

return this.Context.Vendor

.Include("CountryISO3166_1")

;

}

public void InsertVendor(Vendor vendor) {

this.Context.AddToVendor(vendor);

}

public void UpdateVendor(Vendor currentVendor) {

this.Context.AttachAsModified(currentVendor, this.ChangeSet.GetOriginal(currentVendor));

}

public void DeleteVendor(Vendor vendor) {

if ((vendor.EntityState == EntityState.Detached)) {

this.Context.Attach(vendor);

}

this.Context.DeleteObject(vendor);

}

I have done as little as possible to get this to work. All the code is pretty much the same as when RIA generated it. I have generated the Metadata as well and attached Annotations, Include, Required and so on.

Do I need to annotate the methods in the service ?

Your example has no annotations in the service though, so I'm just lost.

thanks

What does your KerdaService look like? Did you add a query method?
