术语“脚手架DbContext”不被识别为cmdlet的名称

问题描述

我有两个项目的解决方案，一个是主要项目，另一个是使用EF Core 10.0 RC2的项目。

在第二个项目中，我使用这三个命令安装EF Core并运行这个nuget命令来安装它：

  Install-Package Microsoft.EntityFrameworkCore.SqlServer -Pre 
安装包Microsoft.EntityFrameworkCore.Tools -Pre 
安装包Microsoft.EntityFrameworkCore.SqlServer.Design -Pre 
  

稍后，我可以使用以下命令从数据库创建我的模型：

  Scaffold-DbContext 'server =（localdb）\mssqllocaldb; Database = Blogging; Trusted_Connection = True;'Microsoft.EntityFrameworkCore.SqlServer 
  

问题是，如果我退出VS2015并再次打开，如果我尝试运行相同的命令再次生成模型，我得到这个错误：

我不知道是什么问题，我已经尝试安装实体框架命令但是问题没有解决。

解决方案

你是否尝试过这个命令：

  dotnet restore --infer-runtimes

I have a solution with two project, one is the main project and the second a project that will use EF Core 10.0 RC2.

In the second project I use this three commands to install EF Core and run this nuget commands to install it:

Install-Package Microsoft.EntityFrameworkCore.SqlServer –Pre
Install-Package Microsoft.EntityFrameworkCore.Tools –Pre
Install-Package Microsoft.EntityFrameworkCore.SqlServer.Design –Pre

Later I can create my model from a database with this command:

Scaffold-DbContext "'Server=(localdb)\mssqllocaldb;Database=Blogging;Trusted_Connection=True;'" Microsoft.EntityFrameworkCore.SqlServer

The problem is that if I exit VS2015 and open again, if I have tried to run the same command to generate again the models, I get this error:

I don't know what is the problem, I have tried to install the entityFrameworks.Commands but the problem is not solved.

解决方案

Have you tried the command:

dotnet restore --infer-runtimes
