问题描述

我正在尝试使用本教程学习如何使用 Razor 页面制作 App.Net Core 应用程序:https://docs.microsoft.com/en-us/aspnet/core/tutorials/razor-pages/model?view=aspnetcore-3.0&tabs=visual-studio

I'm trying to learn how to make App.Net Core application using Razor pages, using this tutorial : https://docs.microsoft.com/en-us/aspnet/core/tutorials/razor-pages/model?view=aspnetcore-3.0&tabs=visual-studio

在我制作好Movie模型并搭建成功后，我尝试进行数据库的初始迁移.

After I made the Movie model and scaffold it successfully, I try to make the initial migration of the database.

但是，每次我使用命令 Add-Migration 时，它只会提示 ScriptHalted，即使使用详细选项时，与 Update- 相同数据库.

However, every time I'm using the command Add-Migration, it just prompts ScriptHalted, even when using the verbose option, same with Update-Database.

我尝试了其他命令，例如 Enable-Migration，它们似乎可以工作，但不是我需要的两个.

I tried other commands like Enable-Migration and they seems to work, but not the two I need.

我有什么遗漏吗?

在我看来，我完美地遵循了教程，并试图在这里找到答案，但我没有提出任何解决方案.

It seems to me that I followed the tutorial perfectly, and tried to find an answer here, yet I didn't come up with any solutions.
