Question

按照官方教程（http://www.asp.net/identity/overview/getting-started/aspnet-identity-using-mysql-storage-with-an-entityframework-mysql-provider），我创建了一个新的MVC项目和我需要的所有文件（MySqlHistoryContext等）。这里没有问题，但教程按＆＃39;运行＆＃39;一切都是正确的，我按下＆＃39;运行＆＃39;并在屏幕截图中获取错误。

模板定义了＆＃34; ApplicationUserManager＆＃34; class，所以StackOverflow中解决的线程对我没用。

的Web.config

Answer 1

乔，我认为这个教程已经过时了，这就是问题所在。

该教程有评论指向最近做过此事的人。这可能有所帮助。 http://k16c.eu/2014/10/12/asp-net-identity-2-0-mariadb/

附注：最新版本的Connector / NET支持EF迁移。当教程创建时 - 正如它所说 - MySQL不支持迁移。由于Connector / NET支持EF迁移，因此最新版本的MYSQL.Data.Entities也支持它。因此，您可能不必按照这些教程中的描述将更改包含在HistoryContext中。

Answer 2

乔，

查看代码后，连接字符串对我来说很有趣。你确定这是正确的字符串。 LocaldB是一个SQL的东西。这是VS的默认值，绝对不是MySql db。

我已经使用带有Identity的MySql db查看了很多教程。他们都没有使用这样的字符串。

MySql dev网站列出了正确的连接字符串。

Answer 3

您的ApplicationDbContext课程缺少静态Create方法。

例如：

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    public static ApplicationDbContext Create()
    {
        return new ApplicationDbContext();
    }
}

此外，您的ApplicationUser课程缺少GenerateUserIdentityAsync方法。例如：

public async Task<ClaimsIdentity> GenerateUserIdentityAsync(
    UserManager<ApplicationUser> manager) {

    var userIdentity = 
        await manager.CreateIdentityAsync(this, 
            DefaultAuthenticationTypes.ApplicationCookie);
    // Add custom user claims here
    return userIdentity;
}

更改Identity SQL存储的错误（官方教程）
