Calling a static method on a generic type parameter
...
In this case you should just call the static method on the constrainted type directly. C# (and the CLR) do not support virtual static methods. So:
T.StaticMethodOnSomeBaseClassThatReturnsCollection

Easier way to debug a Windows service
... 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 Con...

Fastest: exploit the dict co...
Why do we need break after case statements?
Why doesn't the compiler automatically put break statements after each code block in the switch? Is it for historical reasons? When would you want multiple code blocks to execute?

Why do stacks typically grow downwards?
I know that in the architectures I'm personally familiar with (x86, 6502, etc), the stack typically grows downwards (i.e. every item pushed onto the stack results in a decremented SP, not an incremented one).

What are the pros and cons of performing calculations in sql vs. in your application
...
It depends on a lot of factors - but most crucially:
complexity of calculations (prefer doing complex crunching on an app-server, since that scales out; rather than a db server, which scales up)
volume of data (if you need to access/aggregate a lot of data, doing it at ...
jQuery SVG vs. Raphael [closed]
