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.
I have a simple C# Windows Forms application I'm trying to create. on Form1_Load I query my database with a simple request to fill a DataGridView.
If I debug the application, the query executes immediately without issue.
If I "Start without debugging," the connection to the database times out every time with SqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
This is affecting multiple different projects which used to work flawlessly before today, so I'm pretty certain it's an issue with Visual Studio and not my code. Here's hoping someone knows what could be causing this.
After a fresh install of VS2008 on a new machine, I'm still experiencing the issue. I was able to run the project without debugging, and the first time connecting to the database worked fine, but now it always fails as described above. Possibly some kind of weird connection pool issue in VS?
Check your antivirus software.
My antivirus was flagging every new application I tried to run without debugging, but I had alerts for my antivirus turned off so I had no idea.
I turned on alerts and suddenly when I ran my app I got a notice from my antivirus. I just allowed it permanently and now everything runs smoothly.
Occassionaly, but fairly often, for no apparent reason, VS 2012 will lock up with a dialogue that says, "Waiting for a background operation to finish". E.g. this may happen during a plain old code edit, not on explicitly invoking any IDE command.
What causes this, and is there anything I can do about this?
I am running ReSharper 7, and I am not the only one I know experiencing this.
I was having the same problem, especially in cshtml pages. I found this page: https://devblogs.microsoft.com/aspnet/visual-studio-11-beta-razor-editor-issue-workaround that suggests changing the indent option in Tools > Options > Text Editor > HTML > Tab to Smart instead of Block. In my case it was already set to Smart and changing it back to Block fixed the problem.
Update: I was wrong, that didn't fix the dialogue, it just delayed it until I copied or pasted. What finally worked for me was to go to Tools > Import and Export Settings... > Reset all settings.

It is a very generic diagnostic. It is triggered by COM, heavily used in Visual Studio to implement extensibility. The underlying trigger is the IMessageFilter interface. The trigger occurs when COM marshals a method call to another thread and that call doesn't complete for 60 seconds.
There's little value in the actual notification, it is telling you something you already know. By the time 60 seconds have passed, you typically already have noticed things are not working well. Short from the wee bit of useful knowledge that Visual Studio isn't actually completely dead. The call however has to complete before VS gets usable again. There's little you can do but tap your foot and wait.
This problem is almost always caused by an add-in. Resharper is certainly a good candidate. You find the trouble-maker by disabling the add-ins one-by-one until the problem disappears. It is the kind of problem that's common with new versions of Visual Studio, it takes the add-in vendors a while to get the bugs and hangups ironed out. Contact the vendor for support and in general look for updates that may solve the issue.
Deleting the Solutions "suo" file worked for me.
I was having the same problem and in my case it was DevExpress.
It seemed to hang Visual Studio everytime I did a copy or cut operation, bringing up the message:
"Waiting for a background operation to finish".
Turns out it was actually doing a one off task in the background and it really was taking a while to do it (over 5 minutes).
Perhaps if I had waited normally, it could have gone away, but what finally fixed it was to bring up the Toolbox into view (was hidden/collapsed), which in turn brought up a window saying:
"adding [SomeDevExpressAssemblyNameHere].dll"
this kept updating itself with the name of every dll required by DevExpress to populate the toolbar.
This way I could see the operation progress and after it finished I could use copy/cut paste again as usual.
Hope this helps.
For me the fix was to update the Web Essentials 2012 to version 1.8.
The problematic version was 1.6
Tools > Options > Text Editor > HTML > Tabs -> Identing -> None settings solved this problem for me.
This fixed it for me:
Tools > Options > Text Editor > HTML > Miscellaneous
Uncheck the option "Auto ID elements on paste in Source View"
I will post an update if the problem comes back.
I had this problem for a couple of days, tried uninstalling and reinstalling my visual studio 2012 ultimate edtion SP3...
Still didn't work.
So I deleted all my extensions (git tools for VS 2012 and Nuget Package downloader),
restarted my VS and it worked liked a charm again!
Hope it works !
Good luck!
I experienced this problem while running visual studio in a virtual machine - Virtual Box 4.2 running on Mac OS X Mountain Lion, hosting a fresh Windows 7 install with nothing else installed but Visual Studio. I found that the problem was caused by 2 separate issues.
Firstly, my project was on a folder shared from the host OS. In other words, on the Windows Guest, my project appeared on a network drive. So opening the project in Visual Studio from a network drive seemed to cause this problem because the problem went away when I copied the project onto the C drive of the Windows VM and opened it in Visual Studio from the copy on the C drive.
Secondly, I began to experience the problem again when the hard drive on the virtual machine was getting full. I had about 1GB free space available on the hard drive. When I increased the size of the hard drive on the virtual machine, this issue went away.
Just reproduced similar problem with Codemaid add-on. Found this conversation:
There's a lot of details in this issue, but to try and recap the issue
is that the VS2012 C++ API introduced a deadlock issue when the API is
accessed from a UI thread (e.g. a WPF context like Spade). It wasn't
an issue in VS2010, and Microsoft has fixed it going forwards for
VS2013 but they will not be patching it for VS2012.
Seems to indicate that a fix (for Codemaid) should be coming:
Please keep an eye on this thread for the ongoing resolution of the
issue. It ties in to that larger rewrite so I've been building towards
it by adding a lot of unit tests first to help ensure functionality
remains consistent after the changes.
For me it seemed to be related with the razor syntax, since I only had it on one particular file.
For example if I put the following code in one line I had the described issue.
#section BodyClassName {note}
But when putting the closing parenthesis on the next line the issue went away
#section BodyClassName {note
}
Kind regards

Far from an ideal solution, but please trying running visual studio in administrator mode
i tried virtually everything, and this was the only thing that worked for me
Open Visual Studio, create a new MVC application, close the new application, open the old application and it works!
Check if IIS or another process (BizTalk maybe) is locking your DLLs/references
Kill/stop IIS or the other process if it is
http://geekswithblogs.net/sevenfortytwo/archive/2006/11/23/97947.aspx
RUN> iisreset
Now it is working fine with VS 2012
i think i have found a clue! Every thing is ended to dcomcnfg.exe!
Open it and go under following path:
Component services>computers>my computer>dcom config
after click on dcom you'll see many warnings depend on amount of components on your pc.
Click yes on each message box in order to add correct record for dcom.
I found that VS also loads packages during the "background operation". You can remove unneeded extensions to make the operation faster.
I have it fixed weeks ago after I turn TeamViewer 8 Clipboard Sync off! now it appears back with no reason so I tried reset all settings and it worked for me.
I was having the same problem and running VS as an administrator seems to have done the trick for me (I had posted a similar question at Visual Studio 2012 Express Hangs with Message "Waiting for Background Operation to Complete" on Format Document Command that was marked as a duplicate for this one so I figured I would share here as well).
For me, it was Resharper addon opening a dialog which didn't show. I only found the dialog icon in the hidden icons menu on the task bar. When i got rid of the dialog, Visual Studio returned to normal immediately.
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
Visual Basic 6 is crashing after a new build of my program. Whenever I Start (F5 or Ctrl-F5) my program after making changes to the code, VB6 crashes with the following message:
An unhandled win32 exception occured in VB6.EXE [XXXX].
I can't make any pattern out of XXXX. It's been 5168, 5012, 1488, etc; it changes every crash.
The JIT debugger then offers to let me debug VB6 in VS2010 (which shows nothing but a bunch of disassembly.) If I say no, VB6 shuts down. I can then open and Start my program immediately, and it runs just fine; my changes from before the crash were saved. Alternatively, I can make changes, save them, exit VB6, restart VB6, then run them without a problem. But it seems like as soon as I make any changes, a "crash" flag is set, and if I try and build it before restarting VB6, it simply dies.
I'm only having this problem with specific projects. Most projects work completely normally. It's just this one, and it's branch, that both act in the same manner.
Does anyone have any clue what's going on? Obviously, saving works. And building works. And running works. They just don't seem to work together.
I reinstalled VB6 to no avail.
I ended up on this page after installing VS2010, and just one of many VB6 project wouldn't compile.
Simply go to Project Properties / Compile tab, and uncheck "Create Symbolic Debug Info".
Hope it works for you.
Try to open vb6 project with compability mode as XP. We had some issues related to "make exe" command. Then I started to run VB6.exe with XP compability mode.
Since you're asking for any clues, possible clues may include:
The surprises VB6 experiences when run on Vista/7. Try running elevated/remove elevation.
Same, but applied to a third party ActiveX control you're using.
Not having the Service Pack 6 installed. Install it.
Subclassing issues. Make sure your subclassing, if any, is actually correct.
Whatever problems you'll never figure out. Try reinstalling.
Reinstall VB6, delete the workspace files and then create a new project adding in all your current code files. Then go out and get a job where they use a modern SDK :)
