title: EF CodeFirst migrations not working
body: <p>I am using EF 6 code first .
  I have changed my DbContext to pass connction string to constructor</p>
  
  <pre><code>public class EFDbContext : DbContext
  {
      public EFDbContext(string connectionString)
          : base(connectionString)
      {
          Database.Connection.ConnectionString = connectionString;
      }
      public EFDbContext()
      {
      }
  
      public DbSet&lt;MC_Users&gt; MCUsers { get; set; }
  }
  </code></pre>
  
  <p>and moved connection string from Web.Config</p>
  
  <p>Everything was working fine. But adding one more property to MC_Users,
  is not effecting the database, i mean the code first is not working.</p>
  
  <pre><code> add-migration test    command created a new DbMigration class test
   update-database command applied it successfully
  </code></pre>
  
  <p>but my database table is not changing</p>
  
  <p>Please help</p>
