+Summary: InvalidCastException when casting DataTable.Select to typed DataSet
+
+When using a typed dataset I am unable to cast the results of the select
+method to an array of the typed dataset table.rows.  This is possible under
+windows with .NET 1.1
+
+Steps to reproduce the problem:
+1. Create a typed dataset
+ for example a typed dataset called mytypedDS with a table Day
+2. 
+  attempt the following:
+   mytypedDS mtd = new mytpedDS();
+   mytypedDS.DayRow[] dayrow = (mytypedDS.DayRow[])mtd.Day.Select("filter");
+
+  This generates an InvalidCast error in mono 1.1
+
+mono JIT compiler 1.0.4
+3. 
+  Currently the workaround I have come up with is while processing the
+found rows to cast them individually to the mytypedDS.DayRow  that seems to
+work.  The only issue is with the array.
