Reinitialize a dll

[Morten Snedker]

A few days ago I posted the below as result of the kind reply from
Bruce. I still need an answer on:
Thanks a bunch for your reply!

What does it mean for dll to support a "reinit". How is this defined?

a recycle only unloads the appdomain, it does not restart the worker

The recycling is now disabled to avoid the issue.

Any ideas as to why?

What he meant was that unmanaged (non-.NET) dlls are *not* in the AppDomain
to get unloaded it only holds managed assemblies.
Does that help?

Nah, not really.

The third party dll is a .net dll and should be a part of the
AppDomain. But after the IIS performs a recycle every night, these
third-party dll's aren't accessable. Disabling the recycle works - but
that's not at long term solution.

Thanks for your reply.
