Assembly Dll's, Interfaces and Swapping

[Lee]

Hello,

Assume that I have two dll assemblies that implement a common
interface. If the dll's are named the same, is it possible to swap the
dlls in the field? Say, shut down the software, swap the dll's and run
the software again?

Lee,

If the file is loaded privately (not in the GAC) than, yes you can swap
them. Make sure they are not strongly signed or if they are they have the
same strong name (including version).

Make sure also that all public types and interfaces and their visible
members have the same names.

In the case of GAC deployed assemblies I believe you can swap the
application config file and use different version redirections.

Lee, I don't know what you are trying to achieve there, but I believe there
must be more elegant solution.

Stoitcho Goutsev (100) enlightened me by writing:

Thanks for the info, Stoitcho.

I am writing an abstraction layer for database access. Not a full
blown OPF, but in the same spirit. At any rate, I'm looking for ways
to make the specific layer used for the database (FirebirdSQL, SQL
Server, Access, etc) swappable in the field without recompiling.

Thanks again
