+Summary: Simple Data Table created by Visual Studio generates an exception
+Please fill in this template when reporting a bug, unless you know what 
+you are doing.
+Description of Problem:I created a simple windows form app with a 
+datatable and a data grid. The datatable has two columns and a primary 
+key. When you create the primary key you get the following exception 
+Unhandled Exception: System.ArgumentException: Column must belong to a 
+in <0x0008d> System.Data.UniqueConstraint:_validateColumn 
+(System.Data.DataColumn column)
+in <0x0008f> System.Data.UniqueConstraint:_validateColumns 
+(System.Data.DataColumn[] columns, System
+.Data.DataTable table)
+in <0x0001b> System.Data.UniqueConstraint:_uniqueConstraint 
+(System.String name, System.Data.DataCol
+umn[] columns, Boolean isPrimaryKey)
+in <0x00020> System.Data.UniqueConstraint:.ctor (System.Data.DataColumn[] 
+columns, Boolean isPrimary
+in <0x00132> System.Data.DataTable:set_PrimaryKey (System.Data.DataColumn
+[] value)
+in <0x0047d> MonoTest.Form1:InitializeComponent ()
+in <0x00013> MonoTest.Form1:.ctor ()
+in (wrapper remoting-invoke-with-check) MonoTest.Form1:.ctor ()
+in <0x00018> MonoTest.Form1:Main ()
+However the column does belong to a table, but the DataTable doesn't 
+think it does because the datatable is still inside of BeginInit..EndInit 
+so it hasn't actually added the columns to the table yet.
+Steps to reproduce the problem:
+1. Run the attached progam
+Actual Results: Exception
+Expected Results: To see an empty data grid
+How often does this happen? always
+Additional Information:This program has no code in it not generated by 
+the visual studio form builder.
