Silverlight 4 memory leaks -

-

i have silverlight 4 application has leaky viewmodel class. have confirmed using windbg , !gcroot command on viewmodel type. unable pin point exact cause of memory leak have attempted resolve using following line of code in corresponding view when closed:

htmlpage.window.navigate(new uri(mytopleveluri));

this forces app restart , hence rootvisual reinitialised. when use windbg can see there no more references holding onto viewmodel class after view has closed.

however, when monitor memory use of app (using sysinternals) continuously increases. may drop if keep opening , closing suspect view end private byte memory set of on 1,000,000k. also, if add code force gc, never recovers memory allocated. should worried?

are there inherent memory leaks sl4 , controls? don't have faith given patch released fix memory leaks datatemplates (version 4.0.60129.0 http://timheuer.com/blog/).

it appears answer original question (are there inherent memory leaks sl4?) indeed yes!

the 2 leaks described in links above have apparently been fixed in sl5.

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.
