Hi Alex,

Thanks for your followup.

Based on the further error message you attached below

===============
Compiler Error Message: CS1061: 'System.Data.DataTable' does not contain a
definition for 'AsEnumerable' and no extension method 'AsEnumerable'
accepting a first argument of type 'System.Data.DataTable' could be found
==============

the compiler is still complaining against some certain assembly that is not
referenced. I haven't received the project you sent me yet, would you
verify it? Also, would you please list all the "assemblies" you've
referenced in your project here so that I can have a look and verify
whether there is any necessary assembly that is missed.

Sincerely,

Steven Cheng

Steve,

Thanks for the code change suggestion. I have implemented your suggestions
for adding the appropriate extension. Now I am getting this error as
below.
Any suggestion. I am emailing to you the zipped file

Hi Alex,

Regarding on the error message you provided, it seems the problem is due
to
the "system.Data.Dataset.Extensions, version 2.0.0.0" assembly not
found. I
think that assembly is of the former LINQ extension(used for .NET 2.0 +
VS
2005 ). While currently the latest release of LINQ is provided by .NET
3.5
and VS 2008. It use the following assembly:

System.Data.DataSetExtensions, Version=3.5.0.0
