.NET

Since C# uses Garbage Collection. When is it necessary to use .Dispose to free the memory?

I realize there are a few situations so I'll try to list the ones I can think of.

If I close a Form that contains GUI type object, are those objects dereferenced and therefore will be collected?
If I create a local object using new should I .Dispose of it before the method exits or just let the GC take care of it? What is good practice in this case?
Are there any times in which forcing a GC is understandable?
Are events collected by the GC when it's object is collected?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
