Namspace and Using Statements
-
There was a thread on this a couple of years back though don't recall exactly when. Found this as well: c# using statements placement[^]. Seems to be more of a preference thing - I prefer outside.

Yeah, I've always put them outside because I've never had more than one namespace in a file (which is where it appears to actually make a difference).

"Why don't you tie a kerosene-soaked rag around your ankles so the ants won't climb up and eat your candy ass." - Dale Earnhardt, 1997 -
We are using StyleCop at work and I happened to ask my boss if there was a way to turn off the inside-the-namespace placement of using statements, and he informed me that there were subtle differences in the way .Net resolves class names depending on whether your using statements are inside or outside of the namespace. I accepted that, and then he added that only one of our assemblies can't be placed inside the namespace, but that he wasn't sure why. When I tried it, sure enough I got an Error 43 (
_“The type or namespace name 'Namespace2' does not exist in the namespace 'Namespace0.Namespace1' (are you missing an assembly reference?)”_). The problem turns out to be that of all the (dozens of) assemblies in the solution, only one doesn't have theNameSpace0namespace prefix, which instead is justNamespace1.Namespace2. Given the extensive use of the namespace elsewhere in the code as it exists today, I'm not sure we should try to "fix" the problem. Sometimes, sleuthing can be as interesting as writing the code itself, even if it turns out to be a bad idea to fix the problem.".45 ACP - because shooting twice is just silly" - JSOP, 2010

"Why don't you tie a kerosene-soaked rag around your ankles so the ants won't climb up and eat your candy ass." - Dale Earnhardt, 1997The big issues with where you place namespaces comes with namescope collisions, whereby putting the using statement inside your namespace conflicts with something you define locally. This results in the compiler being unable to decide how to compile this up, which results in a compiler error.

Nope, he's a very long-serving member of staff who comes from the Delphi world. I count myself very lucky that he's not above me in the team hierarchy and my team leader tends to agree with me on most things. The colleague in question has cemented his place in the company forever because he's one of only a few who have in depth knowledge of our legacy Delphi stuff (conveniently undocumented of course), which I refuse to touch because I didn't spend the last 12 years getting proficient in .net just to go and live in the past. Oh yeah, I almost forgot another couple of gems: "You have far less deployment issues with COM .dlls than .net assemblies" "There's too many assemblies in your web front end and wcf application (11 including unit test projects and implementiations totally decoupled from their interfaces), can't you reduce them?" - while he has solutions with 50+ projects, no meaningful unit tests and point blank refuses to use UML to visualise the bird's nest of dependencies he's just created I've taken to just saying whatever mate. trying to reason with him is like trying to teach calculus to your dog. If I was in charge I'd get all the legacy stuff documented in detail and tell him to get his act together or find another job. Attitudes like his are just a barrier to quality, progress and productivity, some of which has rubbed off on someone who sits next to him but that's an entirely different rant altogether.

I don't think he means the actual interface. He probably means the classes that implement the interface. It can be hard to tell which class is being used unless you have a breakpoint set at runtime.
