Hi Alex,

My previous reply means the problem is possibly caused by the project
missing some assembly references. You can try adding the following
assemblies to project reference if they haven't been referenced originally:

System.Data.Linq.dll

System.Data.Entity.dll

Also, it seems I haven't received your new zip package. Is it possible
that
it has been blocked mail server due to large file size? You can try
simplified the code and try to avoid including mdf database file(that'll
make the project very large). You've also sent you an email on this.

Looking forward to your reply.

Sincerely,

Steven Cheng

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,

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
