I am getting a feel for ASP.NET MVC 4. I have successfully created a simple CRUD application using scaffolding/code generation. I am connected to a DB on sql server via a connection string. Now I have updated the model class that I used to initially create the code. How do I get this to update the model in the underlying project/add the new field in the database?
我对ASP.NET MVC 4有了一种感觉。我已经使用脚手架/代码生成成功创建了一个简单的CRUD应用程序。我通过连接字符串连接到sql server上的DB。现在我已经更新了我最初创建代码的模型类。如何在基础项目中更新模型/在数据库中添加新字段？
I use linq-to-sql all the time for winforms applications so I'm used to changing a table in SQL server and then dragging the modified table from the solution explorer onto the datacontext. What is the analog in asp.net mvc 4? I don't see a datacontext class (in a data folder) in the solution explorer.
我一直对winforms应用程序使用linq-to-sql，所以我习惯在SQL服务器中更改表，然后将修改后的表从解决方案资源管理器拖到datacontext上。 asp.net mvc 4中的模拟是什么？我没有在解决方案资源管理器中看到datacontext类（在数据文件夹中）。
