如何将EF核心安装到现有数据库中？ [英] How to scaffold EF core to existing DB?

问题描述

我正在尝试使用 Entity Framework Core 对现有数据库进行反向工程。我试图遵循的指示Microsoft ，但出现错误：

I am trying to reverse engineer an existing database using Entity Framework Core. I tried to follow the directions from Microsoft but I am presented with the error:

无法找到名称为EntityFramework的提供程序程序集。确保指定的名称正确并且已被项目引用。

Unable to find provider assembly with name EntityFramework. Ensure the specified name is correct and is referenced by the project.

我正在从项目目录运行以下命令：

I am running the following command from the project directory:

dnx ef dbcontext scaffold "Server=REMOVED;Database=REMOVED;User ID=REMOVED;Password=REMOVED" EntityFramework

我在做什么错了？

推荐答案

确保您位于项目文件夹中，而不是解决方案文件夹上下文中。昨天我可以将其与以下代码一起使用（注意EntityFramework.MicrosoftSqlServer最后）

Make sure you are in the project folder and not the solution folder context. I was able to get this to work with the following yesterday (Notice the EntityFramework.MicrosoftSqlServer at the end)

dnx ef dbcontext scaffold "{connectionString}" EntityFramework.MicrosoftSqlServer

编辑：

确保在project.json中包含以下内容：

Make sure to include the following in your project.json:

EntityFramework.MicrosoftSqlServer.Design
