Last change on this file since 3380 was 3011, checked in by kgrading, 15 years ago

changed the complete DAL to LINQ 2 SQL (with the exception of the job streaming), did a lot of refactoring, Introduced DTOs (that are named DTOs for better understanding), added the spring.NET Interceptor, reintroduced transactions and cleaned up the whole JobResult thing and updated a part of the config merger (#830)
