domain service wizard doesn't see my entity model

Hi

I have vs2013 community edition, sql2012, win 7, and I am trying to build an Silverlight bussiness app, I am working whith EntityFramework 6.X (even tryed with 5.X), installed the  OpenRIAServices.msi and OpenRIAServices.VisualStudio.vsix, using .net framework 4.5.1 (even tryed with 4 and  4.5 )

I use nuget to update my entity framework to the last one 6.1.2

 I do this:
1. create the project

2.Add an entity model base on my database,

3.Build the solution

4.Add a "domain services" and here is the problem I always got this:

the conectionstrings on the web.confg are

  <connectionStrings>
    <add name="DefaultConnection" connectionString="Data Source=(LocalDB)\v11.0;Initial Catalog=aspnet-BusinessApplication2.Web-20150217101723;Integrated Security=True" providerName="System.Data.SqlClient" />

    <add name="rdbEntities" connectionString="metadata=res://*/Models.Model1.csdl|res://*/Models.Model1.ssdl|res://*/Models.Model1.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=SHP;initial catalog=rdb;integrated security=True;MultipleActiveResultSets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" />

I got two days and nothing work!! can anyone got a clue ??

thanks in advance
