I'm super new to coding altogether, and I'm googling as much as I can, but nothing is addressing my latest problem:
https://learn.microsoft.com/en-us/visualstudio/ide/quickstart-aspnet-core?view=vs-2019
I followed this, just trying to get my feet wet, but when I get to the part where I run the webpage in IIS Express, I get an error that says, "The project doesn't know how to run the profile IIS Express."
I did see this, it seems to come closest to addressing the problem, but I'm not sure how to apply the fix, or even quite what it all means:

If this is what I need, how do I do it? If it's not... what do I need to get my debug running in a web browser?
Thanks a ton!
You can try to use visual studio installer, repair the installation and restart your program.
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.
Recently i installed Microsoft Visual Studio 2013 Preview Ultimate on Windows 7. Everything went smoothly except now i can't access www.microsoft.com and www.skype.com anymore. Tried latest IE10 and FireFox, both show blank page when accessing the above mentioned web sites. Firefox in its left bottom corner shows that it is waiting for ajax.aspnetcdn.com.
I'd really like not to reinstall OS on my machine, so i'd appreciate any idea how to fix this. For myself i tried to stop Firewall service and disable MS Security Essentials runtime protection, neither helped.
PS: I can access www.microsoft.com and www.skype.com from another machine in the same local network
UPDATE: i am using tfs.visulstudio.com as my TFS server and it opens fine if i am not signed in. But once i am trying to log in it opens blank, like browser is waiting for something (the same as for microsoft.com and skype.com). Something related to live ID?
Don't think this is the website to post this kind of question but try uninstalling VS2013 preview because you think that's causing the problem. Search in Google for people getting similar problem. I also don't think it is VS2013 because I can't think of anyway of how VS2013 would somehow disable you from going to a certain website. Make sure the sites weren't down at the time or if you're having something kind of Internet server issues.
skype is owned by microsoft, so you can't enter both microsoft pages. This could be related with some kind of ISP (Internet Service Provider) and not with VS2013, or you can try rebooting your router. Last thing i would do is traceroute both address and see where they fall.
I wanted to write this as a comment but I don't have enough reputation yet. Anyway, obviously trying to uninstall the program and trying again would be a good start as already mentioned, but you should also look inside your hosts file for any weird redirections some virus of malware might have set up. It's located at "C:\Windows\System32\drivers\etc" and you can open this inside notepad (might require notepad to be run as an administrator). Check to see if skype.com or microsoft.com are in there and are pointing to a different IP address. If they are you can just remove them and save the file (might require a restart to take effect). If still no luck you should try a livecd of a linux distro to make sure the problem is definitely inside your windows somewhere.
Let us know how it goes.
I am having below mentioned issue when I am running Asp.Net MVC 2 project on windows Azure emulator (dev environment)
I have installed Windows Azure SDK for .NET - October 2012 version and I am using cache feature on my system.
With above error Below one is also comming.
How to get rid of this ?
Maybe I have an stupid solution, but that works with me.
When I begin to recieve the message "CacheInstaller.exe has stopped working", I do the following:
1) Stop the execution.
2) Go to the Role I'm using in the Azure project and open the corresponding Properties page.
3) Go to the "Caching" section and there I uncheck the "Enable Caching" checkbox. After that I checked again.
4) Save*, Run de application and never the warning appear again.
Is weird because nothing should change if you uncheck and check it again an option without save in the middle, but in this case when you do that the file changes (I can see it in the red icon that said something change there, :P)
I hope this helps. Cheers.
Do you have any error messages in the event log that may give more hint.
It could be an issue with missing dlls, do you have the windows server appFabric installed as well on this machine, which may be leading to a conflict with the dlls?
A procmon log might help you see what file paths its looking for.

I banged my head against the wall on this one as well. I finally figured out the problem after digging deep into the crash-dump logs located within: C:\Users\{YOU}\AppData\Local\dftmp\Resources\{GUID}\directory\DiagnosticStore\AzureCaching\
AzureCaching does not allow UNC paths.
As my primary .net dev is from a vm, my documents/projects drive is mapped to my native drive located at: \\psf\Home\Documents\... Once I moved the project to the vm c:/ drive, CacheInstaller worked as intended.
Might as well post my experience as I was unable to locate anything on this specific problem.
I found today that if my system time was more than about 10 minutes wrong then CacheInstaller.exe bailed out on starting the emulator.
That includes the combination of system time and timezone being wrong, presumably as it results in an inability to calculate the correct UTC time at which Azure operates. Fixing the system clock resolved the issue in my case.
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.
