For anyone wondering what is PerfView like I was, let me spare you a trip to google:

> PerfView is a performance-analysis tool that helps isolate CPU and memory-related performance issues.

> PerfView is a performance analysis tool focusing on ETW information (ETL files) as well as CLR memory information (heap dumps). It can collect and view ETL in a variety of ways. Powerful grouping operators allow you to understand performance profiles in ways other tools can't. PerfView is used internally at Microsoft by a number of teams and is the primary performance investigation tool on the .NET Runtime team. Features include:

> - Non-invasive collection - suitable for use in live, production environments

> - Xcopy deployment - copy and run Memory

> - Support for very large heaps (gigabytes) Snapshot diffing

> - Dump files (.dmp)

> - CPU Performance

> - Support for managed, native, and mixed code

> - Can read XPerf logs

> - Profile diffing

On the topic of ETW is worth mentioning UIforETW [0] and in general Bruce Dawson's blog [1].

I wonder why plaintext github link?

https://github.com/Microsoft/perfview there you go.

Hmmm... in the article is says:

  "You can download a free copy of  Visual Studio 2015 Community Edition ..."

If that's anything like the "free" version of MSVC 2013, then 30 days after installing it... it suddenly stops working until you register with MS (using valid email, etc).

No warning, no notice... it just stops and pops up a notice when you try and use it.

Personally, I call that extremely scummy marketing, not "free". Maybe that's just me though.

Its not at all like the free trial downloads of Visual Studio 2013 and earlier; Visual Studio Community Edition is free and not time limited, but its license restricts its use to (from memory) solo devs, small (< 5 developer) shops, open source work (with unlimited team size), and education.

nah, its exactly like 2013 one. It will stop working if you try using it offline (in a VM for example) and will demand online access and microsoft account login.

you just skip it, it will show a yellow warning sign and you won't have access to the MSDN info and a few other things which is pretty much like how the full version of VisualStudio works offline...

seriously WTF people?

yes, you bought this "free version" with your email/identity. Its right there on your pictu... oh, why did you black out your credentials? Do you consider them somehow precious all of a sudden?

Do you give up a phone number to your employer, insurance provider, credit card company? wanna share it?

Also you do realize that you can set up a disposable email address in 10 seconds right? I didn't use one because I don't consider this instance to be a violation of my privacy, privacy isn't about keeping information secret, privacy is about you having the agency to decide who you share it with.

In the 2013 edition, there is no "skip it". Any action other than signing in/registering just closes MSVC.

If there's some way around that, please I'm all ears. :)

Eh yes there is, you just register it once and you sign out, you do not have to be signed in. Here it is http://imgur.com/u8BiQZ9 no trial no nothing,

I don't know what you are really complaining about....

Ahhh. "Just register it once".

I think we're talking about different things.

I figure as much, for some reason you have issues registering software, I'm guessing you haven't been using mobile phones and 99% of the services out there.

RMS would be proud but this isn't exactly a reason to complain.

So, to register it you would need to have internet access? In that case it is unusable for offline work. Even if it works after it has been registered, what the hell would you do when you need to reinstall your system?

Get internet access? There isn't an offline activation for the full version either you might be able to activate it via KMS.

If you reinstall your system you'll need internet access these days, even if it is only to activate windows.

If you restore it from an image you should be probably ok.

But sorry I don't find the excuse of not having internet viable these days.

maybe this will work http://stackoverflow.com/questions/26512908/visual-studio-20...

Visual Studio Community Edition is exactly what I'm talking about. That's the scum marketing version which stops working after 30 days until registered.

If you don't believe me, then actually try it:

  https://www.visualstudio.com/downloads/download-visual-studio-vs

Under the "Visual Studio 2013" option on the left, choose "Community 2013". This will bring up a "Visual Studio Community 2013 with Update 5" view. Download the ISO and install from there.

30 days later, it will stop unless you register.

I know this for sure, having had this exact thing happen when writing up our instructions here:

  https://github.com/sqlitebrowser/sqlitebrowser/wiki/Setting-up-a-Win64-development-environment-for-DB4S

I have snapshots of the VM and all the downloads used while doing it. It's absolutely the Community Edition doing this.

dragonwriter tells you that the current version of Visual Studi CE (i.e., 2015) is not time limited unlike 2013's, and you come back with a link about Visual Studio 2013 community.

I feel like you've missed something.

what part of:

"Visual Studio Frequently Asked Questions

Visual Studio 2015

Community Edition is telling me my trial has expired. Do I have to pay for Community edition?

No, Community edition is free to use. We use the same infrastructure that allows you to unlock VS w/ an online subscription to manage the requirement of signing into Community edition so some of our strings overlap cross these scenarios. _Trial here means the period you can use the community edition before you must sign in_ to fully unlock the IDE."

dont you understand?

No, I just don't believe dragonwriter is correct.

The 2013 page does not say it's a trial version, nor time limited either. Why would anyone believe the 2015 version is any different?

This is the text from the 2013 Community Edition page:

  Visual Studio Community 2013 is a free, full-featured IDE with powerful coding productivity features,
  cross-platform mobile development tools for Windows, iOS and Android, and access to thousands of
  extensions. This edition of Visual Studio is available at no cost for non-enterprise application development.

See anything there about trial version, time limits, etc? No? Me neither.

I misunderstood your complaint and you seemed to be talking about a time-limited trial, not the no-cost registration requirement, but as I reread your post (maybe its been edited, maybe I just didn't read it right the first time) its very clear that that's what you were complaining about.

And, so I thought you were talking about the earlier time-limited trials, and not Community Edition's registration requirement.

So, you are correct that 2013 CE and 2015 CE both require a no-cost registration -- I still find it odd that you would decry this as being something other than a free-as-in-gratis IDE, or that you would describe it as "scum marketing".

To me, any application/program (etc) which says it's free, then some time later (with literally no warning) stops working unless you register with a valid email... is a scummy way of email harvesting.

Just because it's large, well known company doing it doesn't make it non-scummy.

As I said, maybe that's just my way of looking at things. ;)

Even the 2013 is not a trial, it is not time limited, you have likely installed the trial version of the full installation if you are using the online client and not the ISO it asks you what version you want to install.

I have both of them installed on a VM, works offline no problems, you can even cache the MSDN library for offline use =)

I really wish this was the case, but it's not. :(

It is, you only have to register it once during the installation there is no requirement for it to be online or for you to be kept signed in.
