Hi
Enterprise applications in productive environments requires
smooth updating mechanisms without recompiling or reinstalling.
It's not possible to stop an enterprise application, then run
"dub --reforce" and wait until finish. Mostly only few
functions need to be replaced.
Has someone experience with handling upgrading/updating D-Apps
on the fly?
Working with dynamic libraries or distributed components is not
secure enough,
but maybe there are solutions, maybe around base calls and
functions or completely different.

Do you have an example of this being done in any other language?
Essentially whatever code is being replaced, you're going to need
to recompile it. If you're not using dynamic/shared libraries
Adam is pointing you in the right direction.
If it is a desktop application then it is probably easiest if it
communicates to a local service that provides the "replaceable"
functions, when you stand up the new service the app can transfer
the communication to it.
I can't speak to your security concerns.
