c# - Register a default instance in StructureMap -

i have class (myservice) has static property (myservice.context) represents current context (which specific logged in user, changes).

what i'm trying achieve i

objectfactory.initialize(x =>             {                 x.for<imyservice>().use<myinstance>(c => c.use(myservice.context));             }); 

i.e. every objectfactory.getinstance<imyservice>() reference myservice.context

is doable?

update

i can't use singleton pattern since myservice.context changes depending on user making request (via httpcontext).

in pseudo-code above lambda parameter c represents sm context, can return custom result each request. i'm aware of sm's intercept() it's fired after object constructed - not instead.

if can work property there possibility add oncreation method. action provided executed against instance after creation:

objectfactory.initialize(x =>         {             x.for<imyservice>()              .use<myinstance>()              .oncreation(x => x.context = myservice.context;         }); 

or can use lazy initialization , provide func use method executed whenever new instance needed. should execute in right context:

objectfactory.initialize(x =>         {             x.for<imyservice>()              .use<myinstance>(() => new myinstance(myservice.context);         }); 

i hope 1 of methods works you.
