I've installed Visual Studio 2017 and I was playing with Diagnostic Tools. suddenly, after some restarts, the window does not open anymore and I don't figure out how to do it. Anyone knows how can I open it again ?

The selection is a bit hidden, it's in Debug, Windows, Show Diagnostic Tools. It should be with other window settings really to be easily found.

Thank you :-) Exactly where you said ! – Alexandru Aliu Mar 14 '17 at 12:20

Given how many entries merging the Debug | Windows sub-menu into the View menu would add when debugging, splitting the many debug tool windows out is probably a good idea. Albeit not discoverable. On the other hand: quick find. – Richard Mar 14 '17 at 14:37

@Richard It would bring one extra item, since it would be in a submenu, or at least they could be in the Other Windows section. But yeah, Quick Launch also works fine. – Sami Kuhmonen Mar 14 '17 at 18:25

I was able to add it, but was not to be enabled until the next time I debug – ransems May 26 '18 at 19:20
I just searched for hours for the Diagnostic Tools and did not find them in Visual Studio 2017. There was no menu entry in Debug --> Windows for me.
Finally, I wrote 'Diagnostics' into the Quick Launch bar and Visual Studio offered me to install this missing feature... I guess I forgot to check the tools on first installation!

It appears to be buried under Debug > Performance Profiler in now. (Although network is missing) – Reahreic Feb 10 '20 at 13:57

@Reahreic Performance Profiler and Diagnostics Tools are two different things. – Papa Mufflon Feb 11 '20 at 15:02

Note that this also works if you have it installed. Except you should write "Diagnostic" in Quick Launch, not "Diagnostics". – Hans Olsson Feb 16 '23 at 07:10
If you're after a hotkey, the Diagnostic Tools can be reopened by default by pressing Ctrl+Alt+F2.

For other people struggling to find this. Microsoft might have changed how to open the Diagnostics window. Currently for Visual Studio 2019 I went to Debug > Intellitrace to open the missing Diagnostic window.
