I'm suddenly running into an odd problem with breakpoints in Visual Studio 2019 (this is for a C# solution).
Yesterday setting a breakpoint highlighted the entire source code line in the editor.
Today it only sets the red circle in the left-hand margin.
Something has changed but I have no idea what. How do I revert to the earlier behavior?
I still don't know what happened but running the VS Installer and telling it to Modify the setup -- and then not making any changes -- fixed the problem.
Obviously something got messed up somewhere and I'd still love to know what happened. But the problem is gone...for now.

I am making a Xamarin.Forms project, and I am in the end of my app, but something really strange have happened. My app starts up with no labels (!?), meaning they are invisible or not created at all. Everything else seems to be working, until I press a button that is supposed to change the label - when I do this, the app freezes. I get no exception in Visual Studio, though.
One problem is that my breakpoints in PLC code never hits, only those I place in the iOS code. However, the buttons not related to changing a label works, so I know the PLC code have been ran. If I let the app run for a little while, and then press the pause-button in VS debugging to see where in the code I am, it stops at
UIApplication.Main(args, null, "AppDelegate");
.. in Main.cs. I dont know if this is correct or not, when I run on Android, I get a Break Mode - No code is currently running.
I have been trying for hours to debug, reinstall, restart, clean and rebuild, but nothing seems to help. My code works perfectly in Android, and it worked in iOS 1 week ago. Anyone have any ideas what is going on, or what I can do to debug some more? Or must I make a new project and try start over?
Edit: I have also tried different starting pages, and all are the same: all views loads except those with text in them. I have a page with an Editor in it, and I can write in it, but no text is appearing inside of it. Only button have visible text. I do not use a custom font for my labels, I have not specified anything.
Waking up fresh in the morning, I found my issue in 15 minutes..
After altering my Google search to TextView iOS instead of Label Xamarin, I found much more answers. Thanks to this question and answer.
Basically, changing anything on the labels in the constructor of the page (even after InitializeComponent()), will mess up the view. I moved my code outside of the constructor (in the protected override void OnAppearing() method), and now it is working again.
The freeze part was not related - this was my custom menu that covered my screen with an invisible layout eating up all clicking events. A bit confusing, none of these issues are present in Android, but there you go.
When I write anything in a Swift file in Xcode 7, every time I enter an letter, a space or delete anything, the syntax highlighted words in the line go white and then back to their original color. I recorded a gif, better explaining, what I mean:
This first appeared, after I installed Alcatraz and a few plugins. After I noticed the bug, I removed all plugins and then Alcatraz, but the bug still existed. I also tried to delete the Derived Data folder as suggested in a few posts, but it didn't help.
I also created a new project, but the error occurred there too. Downloading Xcode 7.3 beta, didn't help too.
Is anyone having the same issue or knows, how to fix it? It's really annoying.
I just tried to reproduce this bug and figured I have the same issue. Since I don't use such high contrast colours for syntax highlighting, I didn't notice until now.
I presume it's not a bug only you are experiencing, so maybe you could try to file a bug report to Apple here.
This appears to be a result of the constant syntax scanning done by the text engine as you type.
If you find the effect objectionable, switch (for now) to the Default theme (or some other theme that has a white background) instead of the black background you're currently using; it is not noticeable there.
Is it just me, or does this happen to anyone else? Occasionally if I am coding inside of a huge class, the source code text begins to chop it's way out to a white screen as I scroll. However, when I vigorously scroll to the top, then back down again. The source code re-appears again.
What could be the issue? Is there a work around? This issue is so annoying!
Go to Preferences->General tab and uncheck "Show live issues" under Issues. Notice that this is a work around to be able to continue working with Xcode, at least until they issue an official fix. This glitch seems to be noticeable when you have lots of lines of code (1000+).
After this, the glitch will still be happening but not while coding but during building phase. Not perfect but at least you will be able to continue working.
yesterday I updated my Dart Editor to the newest version (25719). When I opened my code in it, some pieces changed into rectangles. I made a screenshot of this problem.
I tried to downgrade to version 24898 of Dart that I used before (and everything was all right), but this not helped, rectangles remained.
Has anyone same problem? Some ideas why this problem appeared?
Thanks for your responses.
In C++ Builder 5, when I set a breakpoint after 'making' my project, the breakpoint does not take. Usually there are dots next to the lines where you can set a breakpoint. I have to re-build the entire project everytime (and it is a large project). Is there a way around this?
The only reason I could come up with is that it usually happens after you do a Program Reset or editing the code during debugging. I will have to live with it until I can update to the latest CodeGear.
