Delphi and COM: TLB and maintenance issues

Question

In the company that i work, we develop all the GUI in C#, but the application kernel is mainly developed in Delphi 5 (for historical reasons), with a lot of components made

Answer 1

Using Delphi 2009 has greatly taken much of the pain out of huge TLB files, and conversion of our existing objects was painless, but our com objects don't use any third party libraries.

We will be migrating our gui applications over once the library vendors release supported versions.
