    copied!<p>I need presentation layer in silverlight, asp.net etc , so everything is through wcf services. I have number of doubts in my implementation of repository layer, service layer, wcf services</p> <p>things i currently do</p> <ol> <li>I have repository , its not per table its created per aggregate root</li> <li>I have service layer its for doing a group of actions involving multiple repository</li> <li>WCF service wraps the methods in service layer and repository layer</li> <li>The entities are auto generated by EF </li> <li>The entities are passed and returned to service layer as complete graph</li> </ol> <p>6.I have two concrete class with all repository , and service called repositorycontainer and service container , Repository container is passed to the service </p> <p>My repository base </p> <pre><code>public class RepositoryBase { public DataBaseContext _Context; public RepositoryContainer _RepositoryContainer; public RepositoryBase(RepositoryContainer repositoryContainer) { _RepositoryContainer = repositoryContainer; _Context = repositoryContainer.Context; } public RepositoryBase() { _RepositoryContainer = new RepositoryContainer(); _Context = _RepositoryContainer.Context; } } </code></pre> <p>My repository container</p> <pre><code>public class RepositoryContainer { public RepositoryContainer() { Context = new DataBaseContext(); } public RepositoryContainer(DataBaseContext context) { Context = context; } public DataBaseContext Context { get; set; } public SurveyRepository _SurveyRepository; public SurveyRepository SurveyRepository { get { return _SurveyRepository ??
