ADO.NET team announced that there will be no further development on Linq2Sql and investments on data access solution with Linq technology will be made on Entity Framework instead. The irony is that the Linq2Sql probably will not be removed from the next release of .NET Framework, because of backward compatibility, so it will not be completely dead! More users are likely switch to open-source ORM solutions like NHibernate, specially with Linq for NHibernate in the horizon.
