asp.net mvc - Should IDependencyResolver.GetServices using Unity return the default (unnamed) registration -

-

i've question implementation of mvc's idependencyresolver.getservices when using unity dependency injection.

there several example implementations found, of have been implemented work around problem of unity throwing exceptions when trying resolve unregistered types.

usualy getservices implemented this:

ienumerable<object> idependencyresolver.getservices(type servicetype) {     try     {         return _container.resolveall(servicetype);     }     catch     {         return new list<object>();     } }

what of concern me, , have been unable find confirmation either way, resolveall not return default (unnamed) registration. see here.

the documentation idependencyresolver not make same statement.

does know whether idependencyresolver.getservices should return registered instances or named instances (using unity parlance)?

try below code. hope work.

return (servicetype.isclass && !servicetype.isabstract) ||        _container.isregistered(servicetype) ? _container.resolveall(servicetype) : new object[] {};

c# - Is it possible to remove an existing registration from Autofac container builder? -

-
something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
