I've lost a lot of days on this and am hoping for some direction even if it is a different site to post on.
I am working on a Blazor Web Assembly application using VS 2022. About a week ago my debugger began no longer stopping on breakpoints in the client application. It does stop on the server app.
At the same time this problem started, I noticed that when I started a debug session it started opening a new tab rather than a new window in Edge; not sure if this is related.
A few points:
The behavior is consistent between MS Edge and Chrome.
If I create a new app, the new app stops on breakpoints.
I am on VS 2022. Tried it on VS2019 on the same laptop with the same results.
Been searching and finding little things to try here and there, but nothing has made a difference.
I can't think of any changes I have made to the environment, etc.
Hoping for some kind of guidance.
Thank you BP and MM for your help.
The problem ended up being in the LaunchSettings.json file on the server app. It was missing the line:
"inspectUri": "{wsProtocol}://{url.hostname}:{url.port}/_framework/debug/ws-proxy?browser={browserInspectUri}",
I have never updated this file and can only assume that it was there before because I have been debugging successfully for quite awhile. I have not upgraded from 5 => 6.
While I don't know the root cause, it is now working. Thanks again.

I have a Clickonce app from Visual Studio 2015 SP3 that is published to the network server and used in-house only. The program works just fine when launched from Visual Studio. It runs just fine on a Windows machine that does not have the 1803 update. But once a machine updates to 1803, the application no longer starts. I get the "Checking for updates..." window then nothing. On a fresh install, I usually get the Smartscreen telling me the program may be dangerous. It doesn't get that far.
I've created the Clickonce from a computer with the 1803 update and the problem still exists.
I've disconnected the machine from the network. The application starts but then has no database access and it needs the database. It's also written to hide buttons that would use the database to prevent users from trying to do things that require it.
I found a workaround (third paragraph) at https://social.technet.microsoft.com/Forums/en-US/7cbd16f5-526e-4b0b-a186-3ebf41b7b349/smartscreen-prompt-does-not-show-for-clickonce-app-since-windows-10-update-1803?forum=win10itprogeneral. When I start the application from the directory mentioned, I get the Smartscreen and can tell it to run anyway. Every time I click the desktop icon, it works just fine.
If a new release is published, the new release is downloaded and the program updated, but the Smartscreen no longer appears and the application never starts.
So somewhere between installing the latest update and the Smartscreen, this is failing. Anyone else experiencing this and have an idea as to why?
Yes, frustratingly I also experienced this today. Presumably a security update that they'll release another patch for given this is quite a pain for developers and users of small business apps.
Rather than disable Defender or SmartScreen I chose to add my deployment website to the Trusted Sites in Internet Explorer and that then re-instated the warning dialog and my app updated and ran as before.
Really annoying given the nature of the issue and how long it took to figure out, but at the same time I had to use IE today, which is a rare event nowadays.
This works for me...Warn doesnt warn anymore...
After running in the same problem, I just found that my application was going to halt after a stupid uncaught exception.
Despite the fact that the image below is in Portuguese, Event Viewer shows the right error cause.
In my case, was a corrupted settings file!
It appears as though some subsequent Windows Updates have fixed the issue on several of our PC's that were previously experiencing the issue.
Check for the updates listed here.

Running winver.exe will show you which build you have.
Has anyone seen the issue when debugging an Asp.Net 5 (core) application where the application seems to just go to sleep. Selecting another function/page in the browser just says "Waiting for LocalHost" (as I am running it locally on IIS Express).
We have a staged version of the Asp.Net app and it has no such problem. It runs wonderfully, but in Debug mode, it can have serious delay issues in executing code. Nothing is reported in the output window, during the time it appears to be doing nothing. Nothing on the Diagnostic tools windows either
A lot of the time - it will ultimately come back if you let it do its thing. But sometimes it can take up to 15-30 seconds.
The issue seems to become more prevalent when you change the Razor or javascript client files while the app is running?
Soemtimes pressing F5 on the web page makes it get out of its sleep mode (but not always, and it seems the more times you do this it, the slower it gets). Is it perhaps rebuilding the page that changed? but why the delay?
Again this works fine in Staging or Production (as none of the back end client side files would be changing). But it can be very annoying
Any ideas?
For me it was my Anti Virus. As soon as I disable AVG all requests get immediately run by the debugger.
So I found I didn't have the web tool extensions even installed - and after I installed it - the Freeze disappeared, but a colleague of mine still has the problem (as he already had the extension loaded and there is no way to uninstall it once its loaded
I'm working on an iPad app and I need to try a few things, for which I usually have a small sample app that I use. While my primary app project opens just fine, the sample app doesn't. Xcode (Version 5.0) just sits there, the wait cursor spinning. The other odd thing is that when trying to make a new project, I get the same behavior.
What's going on here? Various other threads on Stack and other forums suggest removing various files, in ~/Local/... and in the .xcodeproject directory. However this doesn't seem to help. Any ideas as to what's going on?
I restarted my macbook and XCode behaves now. There goes my 200 day uptime...
i was trying to change the table's width in IDE and then saving and refreshing my localhost version of the application. it was working fine but suddenly i found that whenever i made any changes to my design the IDE gets hang and it says not responding and it takes quite much time to resume. after several time of this happening and restarting IDE and computer, i still got the same problem and when i closed the not responding IDE by force then in view error detail i found that APPHangB1 is causing problem, it says something like this "program is unable to communicate with windows due to AppHangB1 ". what is teh problem kindly tell? shall i reinstall my VS 2010. i have stuck in the middle and have to complete my application fast. kindly suggest solutions if u faced any. i m in hurry
Using Visual Studio 2010 on Window 7 64bit. I'm trying to test a website project (not a web application project) using the built in dev server (cassini). The problem I'm having is that when I make a change, I now have to actually stop debugging, kill cassini, and restart before I can actually see my changes in the browser. I used to be able to edit and refresh. One of my fellow developers here is able to do this just fine with an identical setup (same project/vs version/os - and settings near as I can tell). I'm beginning to suspect some sort of permissions issue. I've been all over google trying to find an answer to no avail. Any ideas?
As it turns out, this was my fault... I had experienced the dreaded "network BIOS command limit has been reached" issue. I found a post that recommended doing a regedit hack "HKLM\Software\Microsoft\ASP.NET\FCNMode = 1", well this basically turns off File Change Notifications. Changing this value to 2, and applying the changes recommended in knowledge base 810886 fixed both problems.
