支架-DbContext抛出错误“找不到组件”。在.net核心中 [英] Scaffold-DbContext throws error "Could not find assembly" in .net core

问题描述

我正在使用.net核心和实体框架核心1.1.0。在 Package Manager控制台

I am using .net core and entity framework core 1.1.0. while trying the following command in Package Manager Console

Scaffold-DbContext "Server=MyServer\\MyInstance;Database=MyDB;user=MyUsername;password=MyDbPassword;" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models -t Table1,Table2

我收到此错误

找不到程序集
'D：\Work\Projects\src\MyProject\src\MyProject.Api .\bin\Debug\net461\win7-x64\MyProject.Data.exe'。

Could not find assembly 'D:\Work\Projects\src\MyProject\src\MyProject.Api.\bin\Debug\net461\win7-x64\MyProject.Data.exe'.

MyProject.Data是一个网络核心库。 MyProject.Api是.net完整框架核心api，它引用MyProject.Data。

MyProject.Data is a net core library. MyProject.Api is a .net full framework core api, which references the MyProject.Data.

MyProject.Data的project.json文件

project.json file of MyProject.Data

{
  "version": "1.0.0-*",

  "dependencies": {
    "Microsoft.EntityFrameworkCore.Design": "1.1.0",
    "Microsoft.EntityFrameworkCore.SqlServer": "1.1.0",
    "Microsoft.EntityFrameworkCore.SqlServer.Design": "1.1.0",
    "Microsoft.EntityFrameworkCore.Tools": "1.1.0-preview4-final"
  },

  "frameworks": {
    "net461": {}
  }
}

对我有任何建议吗？

推荐答案

不确定这是否是一个错误，但是 scaffold-dbcontext 命令在启动项目中寻找程序集。

Not sure if this is a bug, but scaffold-dbcontext command looks for the assembly in startup project.

此问题有两种解决方法

1. 右键单击要在其上运行此命令的项目（您的情况是MyProject.Data），然后选择设为启动项目。



2. 您可以将开关添加到脚手架-DBContext 命令在运行命令时将特定项目设置为启动项目。
   这是您需要在命令末尾添加的内容...

1. Right click on the project you intend to run this command on (in your case, it is MyProject.Data) and select Set as startup project.

2. You can add a switch to scaffold-DBContext command to set a particular project as startup project while running the command. This is what you need to add at the end of command...

-StartupProject MyProject.Data
