Ever worked with ILDASM? Does your company understand how the framenwork is based on MS machines? Lets begin by looking into the ILDASM and you will notice that a lot of the framework's classes is wrapped around the Window's core. I never got into VB6 alot (I am fairly new to programming [as a hobby for two years]), but MS claims that .NET is faster than other applications because of the cutting out of the 'middle man' (whatever that layer was -- again, I never got into much detail on that). Whether this is true or not, OOP is definitely the gain with .NET (irrespective of what language it was programmed in). But my point about the stability - it is wrapped around Windows directly... show it to your boss ;) :P !
