WCF for consumption in Silverlight application (Windows Phone 8.0)

Question

I’m having trouble adding to Servicereference, it adds normally but when it will generate the class "Client" it finds the following error:

No endpoints compatible with Silverlight 3 Were found. The generated client class will not be usable unless endpoint information is provided via the constructor.

When creating . svc I selected the new Silverlight compatible item. I’ve also tried to change the windows phone project to version 8.1 Silverlight but also without success. I read in some tutorials that this could be a bug of VS, but also that it had already been fixed (ie, I may be with the version of something outdated, but I’m with VS2015).

When inserting a new . svc and running it empty, it works right away, the problem starts to arise when I enter methods that return of type List<>, the weirdest thing is that the first time I created a WCF project I did the same process and it worked right away, I tried to insert this project (what worked) in Solution and it also did not work in this case.

.SVC:

[ServiceContract(Namespace = "")]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
    public class CargaInicial : ICargaInicial
    {
        LojaService _lojaService = new LojaService();
        UsuarioService _usuarioService = new UsuarioService();
        ProdutoService _produtoService = new ProdutoService();

        public Loja ObterLoja()
        {
            return _lojaService.ObterLoja();
        }

        public List<Usuario> ObterUsuarios()
        {
            return this._usuarioService.ObterUsuarios();
        }

        public List<Produto> ObterProdutos()
        {
            return _produtoService.ObterTodosProdutos();
        }
    }

Interface:

[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class CargaInicial : ICargaInicial
{
    LojaService _lojaService = new LojaService();
    UsuarioService _usuarioService = new UsuarioService();
    ProdutoService _produtoService = new ProdutoService();

    public Loja ObterLoja()
    {
        return _lojaService.ObterLoja();
    }
    public List<Usuario> ObterUsuarios()
    {
        return this._usuarioService.ObterUsuarios();
    }

    public List<Produto> ObterProdutos()
    {
        return _produtoService.ObterTodosProdutos();
    }
}

When entering the reference I used the following settings:

Product class:

[Table("Produto")]
public class Produto : Entity<Guid>, IProduto
{
    [Required]
    public string Codigo { get; set; }

    [Required]
    public string Descricao { get; set; }

    [Required]
    public decimal PrecoVenda { get; set; }

    [Required]
    public DateTime DataHoraUltimaAtualizacao { get; set; }
}

This class is from another project in the same Solution. I tried to insert the [Datacontract] and [Datamembercontract] but I still didn’t succeed.

Perhaps one solution is to change the version of Silverlight in the project, but I don’t know how to do this and I also have to use version 8.0 because it is a requirement.

Answer 1

Whenever I consume a service, I’ve never been able to put the reference on Windows Phone and work smoothly.

Now I always use Restsharp to consume any service (WCF, ASMX, Webapi, etc). Works very well and does not need to include the service reference.

Example:

var client = new RestClient("http://example.com");
// client.Authenticator = new HttpBasicAuthenticator(username, password);

var request = new RestRequest("resource/{id}", Method.POST);
request.AddParameter("name", "value"); // adds to POST or URL querystring based on Method
request.AddUrlSegment("id", "123"); // replaces matching token in request.Resource

// easily add HTTP Headers
request.AddHeader("header", "value");

// add files to upload (works with compatible verbs)
request.AddFile(path);

// execute the request
RestResponse response = client.Execute(request);
var content = response.Content; // raw content as string

// or automatically deserialize result
// return content type is sniffed but can be explicitly set via RestClient.AddHandler();
RestResponse<Person> response2 = client.Execute<Person>(request);
var name = response2.Data.Name;

// easy async support
client.ExecuteAsync(request, response => {
    Console.WriteLine(response.Content);
});
