Is it possible in MEF to instantiate each plugin as a separate process? Or should i have to use MAF?
PS: I see an interesting article at http://pwlodek.blogspot.com/2011/07/isolating-mef-components.html
[ i can not able to run application, it crash]
MEF doesn't support that out of the box. But you could write your own ExportProvider which tries to handle this, and pass it to the CompositionContainer constructor.
