Question

Can someone please post a confirmed example using linq to retrieve and update a record in CRM Dynamics 2011.

Microsoft claims this is “unsupported” but I have a suspicion it is possible.

Answer 1

This is a rough example of using the ODATA provider connected to the online provider

             var serverConfig = GetServerConfig(sessionKey);
            // Connect to the Organization service. 
            // The using statement ensures that the service proxy will be properly disposed.

            using (var serviceProxy = new OrganizationServiceProxy(serverConfig.OrganizationUri, serverConfig.HomeRealmUri, serverConfig.Credentials, serverConfig.DeviceCredentials))
            {
                // This statement is required to enable early-bound type support.
                serviceProxy.ServiceConfiguration.CurrentServiceEndpoint.Behaviors.Add(new ProxyTypesBehavior());

                using (var orgContext = new CrmServiceContext(serviceProxy))
                {
                    return orgContext.AccountSet.Where(item => item.Id == id).Select().Single();
                }
            }

there’s also a good example in the SDK:
