so i could compile it again, while other apps r still running .

I dont think so (or see why you would want to)

If other apps are using the assembly then stopping it could only make the apps crash.

Why do you want to unload the assembly?

Yes you can unload assembly.
The good sample is http://msdn.microsoft.com/library/de...ml/updater.asp
where is SelfUpdatingDemo. This demo contains code which unload running application(assemblly) and run new wersion of application.

i think this sample is good to unload AppDomain.

im talking about this case :
i have winapp that use dll (assembly)
im createing in runtime object from the assembly.
the destroy this object.

THEN , while the winapp is STILL RUNNING , i want to Recompile the dll (assembly) , and to use the winapp AGAIN to create object from that assembly .(this way i could ,change the code of the object ,if i found bug, and use it again).

amirxy:
I have encounted the same problem,
Have you resolved it with the "sample"?
Appreciate for your reply.
