title: Strongly typed datasets and schema changes
body: <p>I have a project which uses strongly typed datasets.</p>
  
  <p>Let's assume I want to change the database schema of the database used by this application.
  I have a table named Country and I want to add a new column named "IsADemocracy" (that's an example) of the SQL Server datatype BIT.</p>
  
  <p>Now, how do I update the strongly typed dataset so that I can use this new field in the application?</p>
  
  <p>I've tried adding the column in the Country table on the dataset, gave it the type of boolean and mapped its "Source" property to "IsADemocracy".</p>
  
  <p>I can access the field in the application, give it a value, etc, but the underlying queries made by the table adapter have not been updated to reflect this change. They are as they were before I added this column in the strongly typed dataset.
  I hoped what I did would be enough but it does not seem to be the case.</p>
  
  <p>Should I regenerate the strongly datasets classes somehow? If so, how and what are the implications?</p>
  
  <p>I could probably delete the Country table in the Dataset designer, and redrop it from the Server Explorer, but I have customer queries on it and I don't want to lose them.</p>
  
  <p>Thanks.</p>
