如何首先从数据库EF模型向现有代码添加其他表？

Question

When creating a new entity data model from an existing database using code first from database approach, one can directly specify which tables to include in the model. A subset (or all) tables can be selected in the Visual Studio wizard:

In this example, Category and Product classes will be created along with the DbContext derived context class. If I later want to add additional tables to the same model, is there a simple way to add them, ie without having to manually create the classes myself?

Eg initially, my DbContext class will contain:

public virtual DbSet<Category> Categories { get; set; }
public virtual DbSet<Product> Products { get; set; }

Now suppose I also want to include Employee table so that the DbContext class will be updated to:

public virtual DbSet<Category> Categories { get; set; }
public virtual DbSet<Product> Products { get; set; }
public virtual DbSet<Employee> Employees { get; set; }

VS context menus don't seem to provide this option, but maybe I'm missing something. Is there a way to bring back the wizard so I can select additional tables?

One solution is to have a separate empty project where you simply create a new model and then copy/paste new classes, but I'm curious if there's a faster way.

No, there is no way to do that. You must run the wizard again, and generate the desired classes.
