Description Dominique NORMAND 2011-09-07 14:00:43 UTC
After cloning a DataTable, the extended properties of columns of the resulting DataTable are gone. Debugging the application shows that the Keys are there but not the Values

Step to reproduce:
------------------

DataTable table1 = new System.Data.DataTable("Table1") ;
DataColumn c1 = table1.Columns.Add("c1") ;
c1.ExtendedProperties.Add("Company","Cegedim") ;

Debug.WriteLine("Before => {0}", c1.ExtendedProperties["Company"]) ;

table1 = table1.Clone() ;
c1 = table1.Columns["c1"] ;

Debug.WriteLine("After => {0}", c1.ExtendedProperties["Company"]) ;

Result:
-------
Before => Cegedim
After  =>

The after value is missing

Fixed in 6c7d6c0. It will probably reach the next MonoTouch beta.
