title: How to update schema on a local database?
body: <p>In the next version of my app, I need to update a column from NVarChar(16) to NVarChar(255) on one of the tables in my local database.  Currently the column is marked up as follows:</p>
  
  <pre><code>[global::System.Data.Linq.Mapping.TableAttribute()]
  public partial class Message : INotifyPropertyChanged
  {
      [global::System.Data.Linq.Mapping.ColumnAttribute(Storage = "_Name", DbType = "NVarChar(16) NOT NULL", CanBeNull = false)]
      public string Name
      {
         ...
      }
  }
  </code></pre>
  
  <p>All examples that I've seen point to the DatabaseSchemaUpdater class, however, it has methods to Add a column, but none to update the length of the column.</p>
  
  <p>How do I update the column length?</p>
