netload - is there a NET UNLOAD command?

[fieldguy]

Is there a way to unload a .dll other than exit autocad?

No.

Thanks

Might there ever be a way? :o) Edited by: mamj@topsoe.dk on Jul 24, 2009 2:22 PM

I don't proclaim to understand all of the possible reasons, but the way I hear it, the reason there is no Unload has to do with the .NET framework, not AutoCAD. The root of the situation is that .NET assemblies cannot be unloaded from an AppDomain.
There is more info here: if you are interested. Edited by: chiefbraincloud on Jul 24, 2009 12:11 PM

However, it is possible to unload an AppDomain. If Autodesk really wanted to, they could figure out a way to unload/reload assemblies. For instance, you could either maintain a separate AppDomain for each add-on assembly, or if a single AppDomain was used, you could unload and reload it without a specific add-on assembly. Either way would have the effect of unloading the assembly. It is possible, but there's no telling how much rework/redesign it would take unless anyone happens to be familiar with the inner workings and design of AutoCAD.

No, they can't do that because it's not possible.

No, because you can't pass AutoCAD API objects across AppDomains. AppDomains are
designed to not be process- or machine-dependent.

IOW, .NET makes no distinction between two AppDomains that reside in the same
process on a single machine, and two AppDomains that reside in two different
processes, each running on two different computers located in different parts of
the planet.

Hence, to go across AppDomains you must use remoting, and few if any AutoCAD API
objects are remotable.

Go look at the Package Contents file, and comment out the <components></components> part of the dll you wish not to have loaded when autocad starts up.
