refresh table data adpter in .net2.0 using sqlserver 2012 in backend

I am working on old .net 2.0 client app. It uses table data adapters and since it was 1st developed several years ago the database has been upgraded to Sql server 2012 from Sql server 2005.

Now I need to make changes to the database and modify new column. I have made the db change. But I am not sure how to refresh the table data adapter for this change. When I try to configure I get the error:

'The server version is not supported. You must have Microsoft sql server 2005 Beta 2 or later.'

I am using visual studio 2005 for this project.

Any pointers to resolving this will be appreciated.
