[英]The type initializer for 'System.Data.Entity.Migrations.DbMigrationsConfiguration`1' threw an exception with Oracle Database
I'm working with Entity Framework 6.1.3, ASP.NET Identity Entity Framework 2.2.1 and Oracle 12C in a ASP.NET MVC5 Project. 我正在使用ASP.NET MVC5项目中的Entity Framework 6.1.3,ASP.NET Identity Entity Framework 2.2.1和Oracle 12C。
While I am trying to generate the database using Nuget command:- 当我尝试使用Nuget命令生成数据库时:-
Enable-Migrations
I am getting the below exception 我收到以下异常

I checked previous questions in StackOverflow, and read the Oracle Documentation .But I can't solve this Problem. 我检查了StackOverflow中的先前问题,并阅读了Oracle文档 。但是我无法解决此问题。

}
So my question is How to solve this error and if i am wrong the how to work with Entity Framework Code first with Oracle Database? 所以我的问题是如何解决此错误,如果我错了,该如何首先使用Oracle数据库使用实体框架代码?
As Per Tetsuya Yamamoto Comment : 据山本哲也评论:
I go to %WinDir%\\Microsoft.NET\\Framework\\%Version%\\Config\\machine.config
and find oracle.manageddataaccess.client
and it's exist in machine.config
. 我去
%WinDir%\\Microsoft.NET\\Framework\\%Version%\\Config\\machine.config
并找到oracle.manageddataaccess.client
,它存在于machine.config
。
so I removed 所以我删除了
<section name="oracle.manageddataaccess.client" type="OracleInternal.Common.ODPMSectionHandler, Oracle.ManagedDataAccess, Version=4.122.1.0, Culture=neutral, PublicKeyToken=89b483f429c47342" />
under configSections
in Web.config
in my project and problem is solved. 在我的项目中
Web.config
中的configSections
下,问题已解决。
Thank's Tetsuya Yamamoto . 谢谢山本哲也 。
