...late to properly terminate with an exit code so you may be better off just calling Environment.Exit.
Another point against using Evironment.Exit - even when writing multi-threaded applications - is reusability. If you ever want to reuse your code in an environment that makes Environment.Exit irrele...

Too verbose
Imperative
Easy to have off-by-one errors (sometimes also called a fence post error)
2. Array.prototype.forEach
The ES5 specification introduced a lot of beneficial array methods, one of them, the Array.prototype.forEach and it gives us a concise way to iterate over an array:

Easier way to debug a Windows service
...e static void DebugMode()
{
Debugger.Break();
}
On your OnStart, just call this method:
public override void OnStart()
{
DebugMode();
/* ... do the rest */
}
There, the code will only be enabled during Debug builds. While you're at it, it might be useful to create a separate Build Co...
What's the difference between dynamic (C# 4) and var?
... An interesting question would be if there are dynamic ancestors of statically declared classes. Example: class X { public int Y {get;set;} } dynamic(X) s = GetSpecialX(); Calling string test = s.Y; would generate a compiler error because the compiler knows about Y but string test2 = s.Z would com...

It turns out that hibernate calls your setRoles method AND it wants its special collection class installed here, and won't accept your collection class. This had me stumped for a LONG time, despite reading all the warnings about not assigning to your co...
What's the advantage of a Java enum versus a class with public static final fields?
...ting to work more in Java. I expected to learn that enums in Java were basically equivalent to those in C# but apparently this is not the case. Initially I was excited to learn that Java enums could contain multiple pieces of data which seems very advantageous ( http://docs.oracle.com/javase/tutoria...
