推荐答案

我已经在你的web.config中看到你有两个连接字符串，但都使用相同的连接和相同的数据库，所以你不需要第二个连接。从您的web.config中删除下面的一行

Point 1 : I have seen in your web.config you are having two connections string but both are using same connection and same db so you don't require second one . Remove the below line from your web.config

<add name="DefaultConnection" connectionString="data source=Dell-PC\SQLEXPRESS;initial catalog=PromoteMyName;integrated security=True;" providerName="System.Data.SqlClient" />

点2：我认为你已经做了一些内置的成员资格Db确定的简单解决方案为您的问题是去你的数据库删除Aspnet / Inbuilt表（我的意思是删除数据库中的表，由代码第一个成员创建）

Point 2 : I think you have done some trouble with inbuilt Membership Db Sure Short Solution for you problem is go to your db remove the Aspnet / Inbuilt tables ( i mean to drop the tables in db that are created by code first membership )

之后删除那些表。现在清理解决方案，然后重新打开解决方案，然后运行解决方案它将自动在数据库中创建新的memebership表。

After removing those tables . Now Clean the Solution and Then ReBuild the solution , Then Run the Solution It will automatically create the new memebership tables in the database .
