    "auto-implemented property" feature.

    Hey,

    Good Day!

    I can't build this project.
    IDE: VS2005

    is it for .net framework 2.0 can't support the new feature, or other reason?
    thanks!

    Code:
    using System;
    
    public class Tmp3Customer
    {
        public int ID { get; set; }
        public string Name { get; set; }
    }
    
    public class AutoImplementedCustomerManager
    {
        static void Main()
        {
            Tmp3Customer cust = new Tmp3Customer();
    
            cust.ID = 1;
            cust.Name = "Amelio Rosales";
    
            Console.WriteLine(
                "ID: {0}, Name: {1}",
                cust.ID,
                cust.Name);
    
            Console.ReadKey();
        }
    }
    Show:
    ....

    Seems like you're right, I can't see any other reason.

    Auto-Implemented Properties (C# Programming Guide)


    In C# 3.0 and later, auto-implemented properties make property-declaration more concise when no additional logic is required in the property accessors. They also enable client code to create objects When you declare a property as shown in the following example, the compiler creates a private, anonymous backing field can only be accessed through the property's get and set accessors.

    Get it.

    C# 2.0 / 3.0 - Lanugage Standard
    .net 2.0 / .net 3.0|3.5 - Microsoft framework version
    VS2005 / VS 2008 - IDE Version

    Could i install .net 3.0|3.5 based on VS 2005?
    How about the compatibility?


    I won't plan to install VS2008...
    A root cause is that all my current development based on VS2005 and
    my laptop is not high performance too.


    Thanks!
