How to use dynamic keywork to work with entity framework

I am using .net framework 3.5 framework & for database operations entity framework. So, to fetch the data i am using LINQ queries & returns a resultset in a list. e.g

public class Emp
{
 public int CD{get;set;}
 public string Name{get;set;}
}


public List<Emp> GetServTypeForPromotionDue()
{
        return (from a in Context.TableName
                    select new Emp{ a.CD, a.NAME });

}

I am planning to migrate from 3.5 to 4.0. I have heard about dynami开发者_运维百科c keyword in .net 4.0. Can i make use of 'dynamic' keyword in order to remove the Class Emp & without creating Anonymous methods?

You could use dynamic for this (e.g. returning List<dynamic>, and building an ExpandoObject in the select clause), but I wouldn't recommend it. You'd lose compile-time type safety, Intellisense etc for little benefit. What do you believe you'd gain from using dynamic? Just removing a few lines of code?

EDIT: Example of using dynamic:

public List<dynamic> GetServTypeForPromotionDue()
{
        return (from a in Context.TableName
                select (dynamic) (new { a.CD, a.NAME })).ToList();
}

Or...

public List<dynamic> GetServTypeForPromotionDue()
{
        return (from a in Context.TableName
                select (dynamic) (new ExpandoObject { a.CD, a.NAME })).ToList();
}
