Overwriting dlls in MEF

Right now, I'm trying to separate out a set of constantly changing classes into their own dll and dynamically load them using MEF. My problem is that whenever I try and overwrite the dll while the app is running, it says it's in use.

Is there anyway to configure MEF to let me overwrite the dll and pick up the changes while the app is still running?

This is not an MEF issue - it is your appdomain standard setup that locks the DLL's touched. Check http://www.vistax64.com/powershell/26164-reflection-assembly-loadfile-locks-file.html for a similar issue not involveind MEF.

Basically, do not run on the dll's, make a copy first and work on the copy ;)

Check http://bartdesmet.net/blogs/bart/archive/2006/07/29/4146.aspx for the AppDomain ShadowCopy mechanism ;)

I suspect it will work if you completely unload any AppDomain which currently references the DLL.
