virtual

It would be much more less work to define which methods are NOT overideable instead of which are overideable because (at least for me), when you're designing a class, you don't care if its heirs will override your methods or not...

So, why methods in C# are not automatically virtual? What is the common sense in this?

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
