Problem solved in RIA

To have best performance of the RIA application, app logic need to be available in client and server side. This problem is solved by auto generating the code at the client side while recompiling the project.
Asynchronous call – Asynch service call are supported in Domain service by using WCF infrastructure
Handling large data and data across different tier – Large amount of data can be access and filter using IQueryable object. Since entity objects used in domain service are serializable and so it can be access across different layer
Security/Access control – ASP.Net membership frameworks are integrated with RIA service to provide security systems to RIA service
Validation – Entity can be validated based using adding attribute to the class members


Example:
  public class Member
    {
        [Key]
        public int MemberId { get; set; }
 
 
        public string Fname { get; set; }
 
        [Required]
        public string Lname { get; set; }
 
        public DateTime JoinDate { get; set; }
 
        [Range(30,90, ErrorMessage="sorry, you are either too young or too old for our club!")]
        public int Age { get; set; }
    }

Tips!

Always create the service with Interface->Implementation format, mention the contract in Interface.
Define the service in Class library and refer the class library in Host project. Don’t use service class in host project.
Change the instance mode to per call as default.
Always catch exception using try/catch block and throw exception using FaultException < T >.
Logging and Include exception should be enable while compiling the project in debug mode. While in production deployment disable the logging and Include exception details.
