c# - 更改身份数据库

Question

我正在尝试更改 Identity 的数据库，更改 ApplicationDbContext:

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    public ApplicationDbContext() : base("BOACopaEntities")
    {
    }
}

我将其从 DefaultConnection 更改为 BOACopaEntities...

我还将连接字符串添加到了 web.config 中。

但是当我尝试运行我的应用程序时，我收到错误:

Unable to load the specified metadata resource.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: System.Data.Entity.Core.MetadataException: Unable to load the specified metadata resource.

Source Error: 


Line 200:
Line 201:            // Sign in the user with this external login provider if the user already has a login
Line 202:            var user = await UserManager.FindAsync(loginInfo.Login);
Line 203:            if (user != null)
Line 204:            {

有人知道我还应该做什么来解决这个错误吗？

这是 web.config:

我设法让它工作......我玩弄了连接字符串。我认为这是因为提供程序类型不能是 Entity.Client，它必须是 Sql.Client...但无论如何...这是对我有用的 conn 字符串:

<add name="DefaultConnection" connectionString="Data Source=xxx;user id=xxx;password=xxx;Initial Catalog=xxx;Integrated Security=False" providerName="System.Data.SqlClient" />
