Do you usually have your main Form's class own the instances of your other objects/threads?
<p>I'm new to C# development.  When I create applications I typically break them up into logical classes.  For example, I have a "Map Display" program, that will display a map on the form screen.</p>

<p>Do you generally have the main form "own" and instantiate your other objects and threads you create for that Form?  Is this bad practice to have your Forms class own your various other classes (Map class, Pathfinding class, Other threads, etc)?</p>
