Does the <domainService> Tag still work for Silverlight 5 and RIA Services?

I am trying to add a JSON endpoint to a WCF RIA Service.

I have read many tutorials on this and I have also watched videos on silverlight.net.

Everywhere I find something on this topic, I am told to use the domainService Tag in web.config.

One code example looks like this:

<system.serviceModel>
<domainServices>
  <endpoints>
    <add name="JSON" type="Microsoft.ServiceModel.DomainServices.Hosting.JsonEndpointFactory, Microsoft.ServiceModel.DomainServices.Hosting, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
  </endpoints>
</domainServices>
<system.serviceModel>

This is not working and there are two issues:

  1. In Visual Studio 2010 the domainService Tag is underlined blue, with the hint, that this is an unexpected tag.
  2. In IIS the domainService Tag is producing an unknown element error.

Among others, I have referenced the following DLLs in my web project:

-Microsoft.ServiceModel.DomainServices.Hosting

-Microsoft.ServiceModel.DomainServices.Tools

-Microsoft.ServiceModel.DomainServices.LinqToSql

-System.ServiceModel.DomainServices.EntityFramework

-System.ServiceModel.DomainServices.Hosting

-System.ServiceModel.DomainServices.Hosting.OData

-System.ServiceModel.DomainServices.Server

I also have the WCF RIA Services V1.0 SP2 installed.

I really don't know, how to resolve it. I need help. I have googled and searched excessively.

Thank you.

This case is solved. Please read my comments to Jeff's answer. You may find some additional information on this problem.

Solution

  • The JSON endpoint is part of the WCF RIA Services Toolkit, not the product itself. You can get the Toolkit MSI here: http://www.microsoft.com/en-us/download/details.aspx?id=26939

    However, I recommend pulling the JSON endpoint in through NuGet instead, using the RIAServices.Endpoints package: http://nuget.org/packages/RIAServices.Endpoints

    Here's some more information about the NuGet packages available: http://jeffhandley.com/archive/2012/12/10/RIA-Services-NuGet-Package-Updates-ndash-Including-Support-for-EntityFramework.aspx
