c# - Is it best practice for every property on a class to conform to an interface? -

-

i increasingly seeing examples of style. happens irrespective of whether interface ever needed. in other case, adoption of new interfaces prove helpful. however, cannot predicted whether used or not new interfaces created new properties conform to... best practice or not?

as usual, depends. if you're writing public api, approach extremely powerful. example of progistics / connectship api. @ time used it, there single concrete class. rest of public interface interfaces. able rip out entire implementation of product , rewrite it, leaving interfaces untouched.

of course, there cost associated this. have put lot of front time , effort making elegant api if you're going want cast in stone (of course, case whether choose use interfaces or not).

on other hand, if you're writing data access layer internal business application, might not reap many rewards.

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.
