实体框架未出现在Visual Studio 2017中的添加新项目列表中 [英] Entity Framework not appearing in Add New Item list in Visual Studio 2017
问题描述
但是,我找不到以前版本的Visual Studio中可用的Entity Framework组件。有谁知道他们去哪里了?

命令。这包括从现有数据库中构建代码优先的 DbContext
的方法。请参阅 ASP.NET核心 - 现有数据库。
为了验证这一点,我设置了一个具有以下结构的演示项目:
新项/数据对话框 .NET Framework 项目:
请注意,还有一个 EF POCO Generator

In .NET Framework-based projects, the Entity Framework 6 templates are still there. However, for .NET Core-based projects, I believe you're expected to use the dotnet ef
commands. This includes a means of scaffolding a code-first DbContext
from an existing database. See ASP.NET Core - Existing Database.
To verify this, I setup a demo project with the following structure:
The New Item/Data dialog for the .NET Framework project:
Note that there is also an EF POCO Generator
template available in the Online templates section that may be of interest to you:
