title: Nullable types in strongly-typed datatables/datasets - workarounds?
body: <p>Strongly-typed DataTables support "nullable" field types, except that the designer will not allow you change the setting to "allow nulls" for any value type fields. (ie: String types allow nullable, but int's do not). </p>
  
  <p>The workaround is to call IsMyFieldNull() any time you want to get Myfield. If you access MyField when it does contain a null, it throws an eception.  </p>
  
  <p>This is a massive headache, in addition to causing many runtime bugs when a null showing up can cause your app to crash. I've complained to microsoft for years about this, yet every new release of visual studio still does not allow nullable value types to be used. </p>
  
  <p>My question: Anyone know of a fancy extension method(s) that could be used to work around this major shortcoming?</p>
