i start studying MVC, had no idea about it last week, was doing all my work using asp.net. After attending a few user groups, and reading Scott Guthrie's blog i decided to study it. A very newbie, little knowlegde but trying to learn. Whenever i have time, trying to contribute a little to a open source blogging project called YABE (Yet Another Blogging Engine) hosted at codeplex. Mostly i am doing unit testings, and using rhino mocks to unit test some of the functionalities, as i am also kinda new to rhino.mocks, i am learning this too :). 

today i experienced something that caused me an hour to figure out. If you insert an object with a child object that botly created new, linq will insert them both, however not the same as delete :)

it wont delete the foreignkey related objects automatically.
