Question

If we have developed our own ORM framework and the framework is working fine over the years then why should we learn and use brand new .net technologies like LINQ or Entity Framework or NHibernate or CSLA.NET for our upcoming software projects?

Note : New frameworks need new effort to learn and teach.

Note : This is just an analogy.

Answer 1

1. Because new developers will know the newer frameworks, but not yours
2. So you don’t have to waste time maintaining code that Microsoft would maintain for you

BTW, “LINQ”, per se, is a technology complementary to your framework
