However, if you try to apply this pattern to HttpClient, another IDisposable class, you trip over some rather unexpected problems...When you dispose it, it starts the process of closing the socket(s) that it controls. Which means you have to go through an entirely new connection cycle the next time you make a request.
I'm sorry, but my response is "well, like, duh." I knew that ages ago (I guess .NET 2.0, so yeah, maybe I had read the 1.10 doc) when I did some performance tests of opening/closing HttpClient connections when I was writing a client-server app. First thing I did actually was check the performance of constantly re-opening a new connection every time I wanted to talk to the server.
And wrapping an HttpClient is a using block? I don't even do that for a SQL connection. In fact, I rarely (and I mean, blood dripping rare) ever use using.
The DNS thing I never encountered because this was all intranet stuff.

I choice to use using rather than dealing with thread unsafe static/shared variables. Dealing with the later one quite a pain especially in web environment.
For sake of fixing the bug, Those teams that are working on HttpClient development should learn and adopt something from WCF team.

Well, I tend to throw async things into a workflow, which queues the work onto threads, so connections usually need to stay open because the response doesn't happen right when/where the listener connection is created.

As general rule, Be very careful about static/shared variables in web environment. You'll get threading issues with their content.
Assuming that when you say "queue" you are talking about a message queue(RabbitMQ, ZeroMQ, NetMQ, MSMQ,...), I'll suggest to revise the design. Keep in mind also queue by itself has a network latency.
First of all I'll not wait an open connection till the message queue completed and send back a response. It doesn't make sense to me. What I'll do, Once a message comes, processing asynchronously, open the http connection, enqueue the message to the queue, then I will immediately send a response saying "you message are being processed" sort of thing and finally close the connection. Then I'll run another separate background process which will dequeue the message and process the necessary busy related task and send it back by opening another http connection.

Employers nationwide are having a tough time finding workers who can "communicate clearly, take initiative, problem-solve and get along with co-workers." "Common sense is as rare as genius."
|
|

Probably because most of those gets knocked out of interviews before they have a chance.
You know, like a not as well written resume.

They say they want people that can "take initiative", but when you do something you're not tasked with doing, or that isn't logged into team foundation as a bug, everyone freaks out, and you end up getting in big time trouble for wasting company resources.
Beyond that, most people don't know how to communicate with a programmer. The good programmers have already mentally fixed the bug and are already four-five steps ahead of the perceived problem, talking about the possible side effects, when everyone else is still trying to comprehend the nature of the bug itself.
This is usually the point where the programmer tunes out of the conversation, and fantasizes about finding a new job where everybody is a programmer, and where meetings like this are a lot less likely to happen.

Been there, got yelled at. In fact, in my last review they asked me to take "more initiative" I told them everytime I do you yell at me. "Oh".

The piece that HR types are missing is that there are lots of folks with those skills, they're just no longer willing to put them to use for a company that will lay them off to give the CEO a 1/2% increase in his stock portfolio.
I'm not going to put forth my best effort for the enrichment of others. The democratization in many areas that the internet has given us means that people's most creative efforts are put towards personal projects. They won't be given for the sake of a company's shareholders.
I suppose you could call it the most passive-aggressive work stoppage of all time.

The weird part is how many employers actually freak out when you "communicate clearly." Of course, what they mean is that they want works to "clearly communicate what we want to hear."
And getting "along with co-workers" does not include communicating clearly to your boss that a specific co-worker "is in over their head." (I was being kind.)

In a serious vein, why are people so freaked out about what non-private settings are turned on for Windows 10, but utterly apathetic about the same with Android (which makes it all but impossible to actually turn some settings off.)
|

For me, one of the reasons is that it's on my desktop and control is being taken away from me where before I had it. On my mobile device, I guess I've just kind of accepted not being able to have as much control (although android gives me much more than iOS). Also, I do less things on my mobile device (intentionally, for privacy reasons) than I do on my desktop so that somewhat mitigates the intrusion/snooping factor.
You're right that it's not completely rational, but it is what it is. Mobile devices have always sort of "been that way", whereas desktop computer users have usually been able to have more control of their computing experience. I think at least on a subconscious level, peoples' reaction to MS exerting more control is due to this shift that is taking place. I think if mobile devices had started out the same way PCs had, there might be a similar reaction.
One of my big problems is that with Windows 10, it is like MS is trying to turn my computer into a "device", rather than my tool over which I have control. I understand that some people really see this as a big benefit or a plus. Me, not so much. No judgement there; everybody's tastes are different. But the problem is MS has given me no way of easily turning it off or opting out (hunting through the registry and various configuration screens doesn't count) other than staying with MS and complaining vociferously or jumping ship and going with another OS.

Windows 10 does need a "Turn it all off" button, after which I'll turn on what I need.
