Should programmers use SSIS, and if so, why? [closed]
As a .NET developer, for what reasons should I prefer SSIS packages over writing code? We have a ton of packages in production where I currently work, and they're a nightmare to both "write" (perhaps draw?) and maintain. Each package looks like a bowl of multicolored spaghetti with C# and VB.NET s...

Why catch and rethrow an exception in C#?
...
C# (before C# 6) doesn't support CIL "filtered exceptions", which VB does, so in C# 1-5 one reason for re-throwing an exception is that you don't have enough information at the time of catch() to determine whether you wanted to actually catch the exception.
