Hi all, I've created an entity model using Entity Framework 4, which I've exposed via a WCF Data Service. One of my entities needs to have properties defined that are not persisted to the database, but the Entity Model designer doesn't allow you to do this. To get round this I've defined all my objects as POCO objects, which allows you...
I recently come to know that there are web services by WCF for Active Directory. I presume this is not about LDAP. Are there any documentations or blogs about it as to what the default endpoints are or what the API looks like or does it even talk in SOAP? or can you please shed some light on how to connect to Active Directory Web Servi...
I have created a simple WCF (.NET 3.5) service which defines 10 contracts which are basically calculations on the supplied data.

Hi, Just curious, did anybody use WS-AT protocol to propagate transactions in WCF over the Internet in production(wsHttpBinding)? Is it hard to deploy/support?

I have a WCF service that exposes 1 method GetNextObjectInList(int id) which hits a DB. The WCF service works, more or less, like this: public class MyService : IDisposable { public MyService() { this.IntializeDBConnection(); } public int GetNextObjectInList(int id) { /* uses DB connection */ ...
To start with, I am a newbie in the world of WCF so pardon me if this sounds naive. To my understanding , unlike ASP.NET based websites which use ADO.NET to communicate to the database, a silverlight based app always needs a WCF or RIA services to communicate to DB. We know that ASP.NET websites are not tightly coupled to the database ...

Service : It has the implementation of the interface MyType MyService() : IMyInterface; 3.) Client : It calls the service. My basic question is should 'Service.Contra...
