How to add columns to an existing SQL Server 2008 database table in asp.net MVC 3

Question

I'm looking to add 2 columns to an existing table in my SQL Server 2008 database. I'm coming in on a poorly documented project, so I wondering, is it simply a case of adding to the class and entering add migration?

The class is within an Entities folder in a Models project and the class uses the following attribute..

 [PersistableEntitiesAttribute]

The properties are written as...

   public virtual string Username { get; set; }

Can I add two virtual properties to the class and use the PM to add migration?

Please note I am seeking to keep all data already in the Database and there is no migrations folder in this project.

Asp.net MVC 3 application.

Is there steps I follow to complete this task ?

Answer 1

Not sure if it's the correct way but I simply added the two virtual properties to my class..

  public virtual string ResetToken { get; set; }
  public virtual DateTime? ExpirationDateTime { get; set; }

and then added the same properties manually to the table in the database through the design view.
