I have Azure SDK 2.3 installed on my Windows 7 machine. The target .Net framework is set to 4.0. I'm able to upgrade my solution to Azure SDK 2.3 and build with no problems. However, when I try to run the solution, I get the following error:
Failed to debug the Windows Azure Cloud Service project. The output directory does not exist.
If I revert the solution back to Azure SDK 2.2, the problem goes away. So there's some configuration that's added by the Azure SDK 2.3 upgrade that is causing this issue. This ONLY happens when I'm running the Azure Emulator. One thing I've noticed is that the build process somehow removes the "Debug" folder from the csx directory. When I manually add it back in, the build process removes it again and then I get the same error above. I'm at a loss as to what might be causing this since my "Active solution configuration" is all set to DEBUG for "Configuration" and ANY CPU for "Platform". I've tried all the troubleshooting steps from earlier threads on this issue (with Azure SDK 1.8) with no luck. I would appreciate any helpful suggestions on this. Thanks.
NOTE: Interestingly enough, if I deny all rights to the DEBUG folder in CSX, the emulator launches but then it fails because it doesn't have access to the DEBUG folder. So I'm puzzled by why the VS build process wants to remove that Debug folder.
ANOTHER NOTE: Apparently, it's the normal process for VS Build to wipe out the Debug folder. The run process with debug is supposed to recreate that Debug folder with everything in it. That doesn't happen. I confirmed this by reverting it back to Azure SDK 2.2 and noted that the run w/ debug actually recreates that Debug folder. This recreation process fails to happen when I upgrade to 2.3.
For me, the issue was I changed the Debug Solution Configuration to something other than Debug. Renaming it back to Debug fixed the issue.
I was able to solve this issue by simply uninstalling Azure SDK 2.3 and then re-installing it. That's it!
Got it solved by doing the following:
Change to "Release" configuration.
Build and run.
Change back to "Debug" configuration.
Build and run. No error now.
I was seeing the same error that the csx folder was empty. Doing the following fixed my issue:
Right click your *.ccproj > Debug > Start New Instance
None of the above worked for me, what did work was deleting the file
{YourProject}.ccproj.user
Close and reopen VS, build and run

Everything was fine until yesterday. This must be due to Windows update. No one touched the server. I have tired couple of similar solutions posted in Stack Overflow(all are old questions),none of them worked for me. What I have, Server Windows server 2019, APP netcore 3.1 ,IIS version 10. .net core runtime and SDK both are installed. This was working before. No one touched anything, just stopped working
In the browser appearing
HTTP Error 500.31 - ANCM Failed to Find Native Dependencies
When I executed on the command line
A fatal error was encountered. The library 'hostpolicy.dll' required to execute the application was not found in
When I checked event log. Something like below appeared. But let me tell you in the build
directory we don't have a file like app.runtimeconfig.json
What I have tried
Repair .netcoe runtime and SDK
Restore old DB backup
Reinstall .netcore versions
No pending Windows updates
Restart IIS APP pool also the server
Check file permission
None of them worked for me. If anyone can help, really appreciate.
For this issue, we can't find out that the environment of windows server caused by windows update is abnormal. As you said, it worked fine before.
So please allow me summarize below suggestions as answer.
Suggestions
Copy the publish file named original_file . And paste it in our dev pc or other server which have IIS Management. And test it, this publish file should be works. This step just confirm the publish file is normal.
Create a new website and a new application pool. Create a new asp.net core3.1 application and deploy it. Then check if it works properly under this new site.
The site should be fine in the second steps, and replace it with the original_file. And the application also should be works fine.
The site can't work in the second steps, it means the environment in you server has some problem. It could be registry issue or ApplicationHost.config issue in IIS and so on. If it's very important for you, you can rasie a support ticket and let official engineer help you to figure out what happend in this windows Update
After the third step, if the new site can run the original_file file well. We can compare ApplicationHost.config between the new site and the original one to see if any settings have been changed.
Crash on Azure publish from Visual Studio. The same thing happens in previous versions of Visual Studio, but in the past I've been able to work around the bug by clearing the appdata and if necessary resorting to resetting user settings per the responses to this question about a VS2015 issue.
Azure publish has been working up to now in 2017. Suddenly I am getting the dreaded null reference, and this time clearing the aforementioned data has not helped:
Restarted Visual Studio, restarted machine, cleared data a second time including both roaming and local appdata, all to no avail.
Just for others searching, in my case the issue was that I had previously disabled the "Microsoft VisualStudio Managed Publish" extension in VS2017 (probably in an attempt to get VS to be more responsive). To re-enable it, go to Tools > Extensions and Updates, enable it, then restart VS:
Thank you for your sharing. I have the same case as you. I accidently disabled the "Microsoft VisualStudio Managed Publish" extension in VS2017. The publish menu even doesn't show up in .net core solution explorer. To re-enable it, go to Tools > Extensions and Updates, enable it, then restart VS.
Unchecking/unselecting the Application Insights in the Publish workflow of Visual Studio 2017 fix the error for me.
This can be caused by a validation error in the service definition and configuration files.
Even though the editor doesn't highlight any problems, and the build completes successfully, there can be errors in these files and they are not handled properly when you attempt to publish, giving the null reference error.
I encountered this after modifying the files per these steps to configure SSL. I really wasn't expecting that to be the culprit, but in desperation I was trying everything I could think of that might be causing the problem. As soon as I commented out the change to the <certificates> element, the null reference error went away, and the publish succeeded.
(I now need to work out why the steps for SSL configuration didn't work, perhaps due to a change introduced by VS2017, but that's another story.)
I was experiencing the same issue as the OP. I created a new DB Project and then compared the settings of the new DB Project with the DB Project that was causing the Null Reference Exception upon Build or Publish. I noticed that our output directory was redirected to a non-standard location. After deleting all the files in the bin folder, the Build and Publish started working. YMMV
I found a lot of answers around that -- so may be there are more than one -- but none worked for me.
On my system it worked again after removing the installations for ASP.NET and Azure and installing it newly .. --> evth is fine.
I'm happily in the middle of coding then I try to launch my app in debug mode but I get this error message.
Unable to activate Windows Store app
This app failed to launch because of an issue with its license
The app was launching fine a few minutes earlier so this came as a surprise. I tried restarting Visual Studio but doing so did not help.
I got the annoying "renew your developer license" dialog yesterday I think. It had renewed without issue.
How do I make this error message go away so i can debug my app?
Well, I got it working by deleting the main project's 'bin' and 'obj' folders. Cleaning and Rebuilding wasn't enough. Hope this answer saves someone else the few minutes of confusion I just experienced.
I recently had a similar issue. In my case I had to uninstall the re-install the app to get it working.
Hope this helps someone. Also, to find out further detail about why it failed, you can checkout the event logs:
Event Viewer > Applications and Services logs > Microsoft > Windows > Aps > Microsoft-Windows-TWinUI/Operational
There might be some more detail in there. In my case it was logged as an error event which said the app could not be launched because of a temporary issue with its license.
I just uninstalled the existing version of the app from the start screen, and then launched the app again from Visual Studio and it is launched just fine.
I think the reason behind this is because of renewing the license of Visual Studio and trying to launch an app that was installed when the previous license was active.
I see doing stuff with the bin and obj folders appears to be the accepted answer to this.
I fixed this issue by selecting the 'Uninstall and then re-install my package. All information about the application state is deleted.' check box under the Debug tab of the project properties. You can uncheck it once you've done it once for all future builds.
I haven't had any issue with this solution. Simple fix and you don't have to worry about someone doing something to folders that could cause bigger issues.

I've had this issue a few times now, most of the time deleting the Bin and Obj folders will clear the issue up (These folders are automatically generated during a project build so don't worry about deleting them)
I have found whilst debugging on a remote device (A tablet or phone) that Deleting these folders doesn't solve the problem though - in this case the best solution I have found is just to do a restart on the device I was remote debugging to.
Simple but it works!
I just cleaned my solution and re-started Visual Studio. That did the trick for me - and didn't involve hunting around for files to delete, so you might want to try that first.
go to BUILD-->Clean Solution and click and after its has been cleaned again go to BUILD-->Rebuild Solution. After it has successfully rebuilt your solution just deploy it(Ctrl+F5). This solved the problem for me.
Anyone know the solution for this? Using the latest version of Azure tools and every time I do a build I see these messages in the output window:
Windows Azure Tools: Warning: Unable to delete directory APPROOT.
Windows Azure Tools: Warning: Unable to delete directory WEBUX.
Windows Azure Tools: Warning: Unable to delete directory APPROOT.
Angela, it is very much possible that an application has open handle to these folders and build process could not delete the folder/files so it can update with new binaries. This problem is specific to your machine, not Windows Azure.
If you could not figure out which application is using, what you could do is restart your machine so you know none of any application is using and then start Visual Studio and clean/rebuild your application and see if you still see this error. If you still see the error, I can provide some other troubleshooting info to help you further.
I ran into this error too. Azure SDK 1.7 added a new way to deliver 'extra' file resources upto the roles. To fix my this error, I manually deleted the folders under the Azure project, Profile roles after exiting VS.
As Avkash mentioned, some app is using your files... a few suggestions that worked for me:
1) Prevent antiviruses from inspecting the build folders
2) Disable Windows search service
3) Disable any auto-backup or auto-sync services that look at build folders
HTH
Ok, first of; here's what I did:
Install AZURE tools
Reboot
Start Visual Studio - new Azure project
Add web role (asp.net MVC 4 beta web role)
Hit F5 (debug)
It starts up the storage emulator and the compute emulator and starts to load in runtimes, and then I get a popup saying that the debugger couldn't connect.
Then after some googeling I'm suggested to try to run the application without running the debugger to see if I can acces the application. When I do I get this:
So I figure that IIS does not have permissions to access some file/directory. So I go to IIS and look up the application pool running the app, and it tells me that the identity in use is NetworkService, then I go give NetworkService full permissions to the entirety of the folder IIS has set for the application (which also happens to be the path to the project dir). Still I get the same error. Now I'm more or less out of ideas, but I try one last thing, which is to also give IUSR full permissions to the same dir, but this did not help either.
How can I go about resolving this problem? I haven't tried actually launching my project to Azure yet, cause if I can't even get it to work in development I don't see much point. Any and all help would be appreciated.
I ran into the same error today after uninstalling .NET 4.5/Visual Studio 11 Dev Preview, then installing ASP.NET MVC 4 Beta (this is before Feb 29th when the updated VS 2011 Preview drops).
Since I uninstalled .net 4.5, you just need to do an "aspnet_regiis -i" to ensure the .net framework (4.0) is set up with IIS 7.x this worked for me.
Edit: This will work if you uninstall/then manually install Visual Studio 2012 RTM as well.
I had a similar error yesterday. For me the problem was that the output of the build was empty in the target folder.
I tried to answer a similar question https://stackoverflow.com/a/9411422/182371:
Check %UserProfile%\AppData\Local\dftmp\IISConfiguratorLogs\IISConfigurator.log
file for the error messages. Mode details at
https://stackoverflow.com/a/8432621/182371
Make sure that the build output of your project is not empty. You can do this by going to IIS, find the site with the name similar to
'deployment16(6).WindowsAzureProject2.WebApplication3_IN_0', right
click --> Explore.... Make sure that this folder is not empty and
contains all the files required to start a web project successfully.
As for the Access Denied error:
it could be just an IIS default setting to disable browsing. To resolve that, just navigate to that web site in IIS, find Directory Browsing icon, and press Enable. You will at least see the files inside that directory.
Also try not only 127.0.0.1:81, buta specific document inside that folder, like 127.0.0.1:81/Default.aspx
Take into account the fact that there's sometimes some mess with the ports. You see that in the error message it's port 82, but in your browser it's port 81. So make sure you're using the right port. Or, even better, in your service definition try to use some non-standard port for this to avoid remapping.
I've met the same issue. In the end, I had to reinstall IIS 7.
I got this exact same error and tried a re-install of IIS and the Azure SDK - nothing worked.
Eventually tracked it down to the "IIS URL Rewrite Module 2". I went to the Control Panel and chose Repair and it resolved it. If you have a section in your web.config then this might be the cause.
