c# - Intercepting dependencies in MEF -

-

is possible intercept dependency requests in mef before handled mef?

this useful implementing decorators , advanced lifetime management.

something like...

catalogue.addinterceptor<iexpensiveservice>(b => ... return pool ...);

or even...

catalogue.addinterceptor<iexpensiveservice>(b => new decorator(b()));

(where 'b' underlying mef resolution func resolving service)

not out of box, can write own exportprovider or composablepartcatalog implementation this.

mefcontrib appears have implemented that, take @ interceptingcatalog. see (possibly outdated) blog post it.
