I have a website using Entity Framework. A few months ago I added a new table, and added some columns to existing tables; everything worked fine.

Today I updated the mapping of the EDMX so the new table and the new column can be used, and added WebMethods to my services.asmx file. Since then I cannot run my site because I have that error that I cannot understand. Please explain it to me if you understand, and tell me where is my mistake.

I have not used datetime2 anywhere. There is no such datatype in my new table, nor in the columns that I added to existing tables.

The version of SQL on my PC is SQL2008 R2, on the server i have SQL2008. I do not have the option to upgrade the server to R2.

回答1:

In addition to @Mithrandir answer validate that your database is running in compatibility level set to 100 (SQL 2008).

You don't have to use DATETIME2 in your database to get this error. This error happens usually once you add required (NOT NULL) DATETIME column to existing table and you don't set the value prior to saving the entity to database. In such case .NET will send default value which is 1.1.0001 and this value doesn't fit into DATETIME range. This (or something similar) will be source of your problem.

回答2:

Have you tried to open your EDMX file with XML Editor and check the value of ProviderManifestToken. It may help to change from ProviderManifestToken=”2008” to ProviderManifestToken=”2005”.

回答3:

Open your EDMX in a file editor (or “open with…” in Visual Studio and select XML Editor). At the top you will find the storage model and it has an attribute ProviderManifestToken. This has should have the value 2008. Change that to 2005, recompile and everything works.

NOTE: You'll have to do this every time you update the model from database.

The other solutions worked for me but I needed a more permanent solution that would not be reverted every time the edmx was updated from the database. So I created a "Pre-build event" to modify the ProviderManifestToken automatically.

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 <edmxFile> <sqlVer>");
                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);
            }
        }
    }
}

Code First workaround.

I got this error while running a linq select query, and changing the EDMX isn't an option for me (Code First has no EDMX), and I didn't want to implement this How to configure ProviderManifestToken for EF Code First for a Linqpad query that wasn't going into production code:

// [dbo].[People].[Birthday] is nullable

DateTime minBirthday = DateTime.Now.AddYears(-18);

var query =
    from c in context.People
    where c.Birthday > birthday
    select c;

var adults = query.ToList();

I fixed it by changing query to null check first:

var query =
    from c in context.People
    where (c.Birthday.HasValue && (c.Birthday > birthDay) )
    select c;
