Using SQL Server 2008 and SQL Server 2005 and date time

Question

I\'ve built a entity framework model against a 2008 database. All works ok against the 2008 database. When I try to update the entity on a 2005 database I get this error.

This is very frustrating and I am surprised MS decided not to make it so you could target a given SQL version. To make sure we are targeting 2005 I wrote a simple console app and call it in a PreBuild step.

The prebuild step looks like this:

$(SolutionDir)Artifacts\SetEdmxVer\SetEdmxSqlVersion $(ProjectDir)MyModel.edmx 2005

The code is here:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;

namespace SetEdmxSqlVersion
{
    class Program
    {
        static void Main(string[] args)
        {
            if (2 != args.Length)
            {
                Console.WriteLine("usage: SetEdmxSqlVersion  ");
                return;
            }
            string edmxFilename = args[0];
            string ver = args[1];
            XmlDocument xmlDoc = new XmlDocument();
            xmlDoc.Load(edmxFilename);

            XmlNamespaceManager mgr = new XmlNamespaceManager(xmlDoc.NameTable);
            mgr.AddNamespace("edmx", "http://schemas.microsoft.com/ado/2008/10/edmx");
            mgr.AddNamespace("ssdl", "http://schemas.microsoft.com/ado/2009/02/edm/ssdl");
            XmlNode node = xmlDoc.DocumentElement.SelectSingleNode("/edmx:Edmx/edmx:Runtime/edmx:StorageModels/ssdl:Schema", mgr);
            if (node == null)
            {
                Console.WriteLine("Could not find Schema node");
            }
            else
            {
                Console.WriteLine("Setting EDMX version to {0} in file {1}", ver, edmxFilename);
                node.Attributes["ProviderManifestToken"].Value = ver;
                xmlDoc.Save(edmxFilename);
            }
        }
    }
}
