Code First Migration Seed [英] Code First Migration Seed

问题描述

当我覆盖种子时，我会遇到以下异常：

When I override Seed I get the following exception:

 

Specify the '-Verbose' flag to view SQL commands being executed during migration.
Found 0 pending migrations: [].
Adding seed data (if Seed method overridden in Migrations Settings class).
An exception occured while updating the database.

我的数据库是在SQL Server中创建的，Update-Database创建我的模型没有任何问题。为什么Seed尝试访问''C：\Program Files（x86）\ Microsoft Visual Studio 10.0 \ Common7 \IDE \'？

My database was created in SQL Server and Update-Database creates my model without any problem. Why is Seed trying to access ' 'C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\'?

推荐答案

对不起，我的错。错误是我在迁移中添加的成员资格代码，以获取用户标识。

Sorry, My fault. The error was with Membership code that I added in migration in order to get User Identification.
