I have an ASP.Net Web forms project in Visual Studio 2022. When I try to build it, an error message appears.
An API call exited abnormally. (Exception from HRESULT: 0x800300FA (STG_E_ABNORMALAPIEXIT))
This error also appears when I try to exit Visual Studio. I have to kill the process to proceed.
The same project works fine in Visual Studio 2019.
Any idea where to start? The error message is not very insightful.
I already tried setting the rights on the framework Temporary ASP.NET Files folder. I didn't help.
The issue is also only with one project - other projects work fine.
Is there a way I can get a Visual Studio log. Any ideal where this is stored for Visual Studio 2022?
Try deleting the .vs folder at the root of your project that fixed it for me
Vs22 is now x64 bits, and is the first such version to be so.
This also means we see a lot more issues and errors in regards to running your application as any CPU as opposed to forcing the project bit size.
It's not clear if you always forced the bit size, or perhaps your project say references unmanaged code that's say x32 bits.
So I would force and change the project to run as x32 bits if that was the settings in the past.
And in fact any CPU used to result in your application (f5) to run as x32 bits, now that default any CPU setting will result in a x64 but running and debug session.
You don't mention your current project settings, but I would try x32 bits, especially if you used any CPU in the past.
I had a same issue after recent Visual Studio 2022 update. Was not able to build, run, publish solution at all. To resolve it I just pushed all my changes into repo and cloned it to new folder.
Have no idea what was a root cause, but it helped...
I was able to get rid of the issue through a combination of the following:
Closed Visual Studio
Removed **/bin/** **/obj/**
Updated Visual Studio to the latest version
Removed the component cache: %USERPROFILE%\AppData\Local\Microsoft\VisualStudio\1x.0\ComponentModelCache
Removed all temporary files in %USERPROFILE%\AppData\Local\Temp
Those locations are also mentioned on the internets, but I didn't touch them:
%USERPROFILE%\AppData\Local\Microsoft\Team Foundation
%USERPROFILE%\AppData\Local\Microsoft\VisualStudio
%USERPROFILE%\AppData\Local\Microsoft\VSCommon
so I was previously using VS2015 in Windows 10. I had built one simple ASP.NET MVC project and never faced any issue while running it. However, I have been using Windows 8.1 now and installed VS2019. Running the same application and been facing the error "Process with an ID of #### is not running".
output says: "The program '[4560] iisexpress.exe' has exited with code 0 (0x0)."
So I tried to open a new dummy ASP.NET Web MVC project to check if that works and it didn't.
Now, there are a myriad range of solutions provided all over and I have tried every last one of them. With no luck.
1. Delete the hidden .vs file.
2 Rename/ remove the IISExpress folder and its config file under documents.
3. Removed the specific code snippet from the solution .csproj file
4. Of course tried running VS as ADMIN.
5. Realised that IIS exress was not installed. So completed that.
6. Then realised that VS 2019 needed to have the IIS support for ASP.net core installed additionally, so done that.
Now I'm out of ideas. It would be really helpful if you could provide some more suggestions or work arounds for this problem.
Thanks.
So, what finally worked for me were the following steps:
Install IIS using this link -
IIS Manager in Windows 10
Run the IIS from command line by following this link -
https://learn.microsoft.com/en-us/iis/extensions/using-iis-express/running-iis-express-from-the-command-line
Opened VS 2019 in admin mode.
Project -> (right click)Properties -> Web -> Servers -> Select local IIS from dropdown. -> Create Virtual Directory -> click ok. -> ctrl+S
Run the application.
I was getting same issue. This problem can be resolved by explorin project directory and remove the .vs hidden folder.
I am creating an ASP .Net Core (2.0) MVC application within Visual Studio 2017 which was working absolutely fine.
After turning off my computer yesterday and coming back to my application today, I now receive this browser error when I start the application in chrome without debugging.
Running dotnet run within the directory of the application, I can access the site just fine. It is just when I run it via Visual Studio/IIS Express I get this error.
HTTP Error 502.5 - Process Failure
The application builds and compiles just fine. I have also cleaned the solution.
Looking in the event logs I find:
Application 'MACHINE/WEBROOT/APPHOST/MYAPP' with
physical root 'C:\Users\Ben Hawkins\Desktop\Development Folder
\Dev\Website\Version_2\MYAPP\MYAPP\'
failed to start process with commandline 'C:\Program Files
(x86)\Microsoft Visual

Tools\ProjectSystem\VSIISExeLauncher.exe -argFile "C:\Users\Ben
Hawkins\AppData\Local\Temp\tmp3547.tmp"', ErrorCode = '0x80004005 :
0.
Within my output window in Visual Studio 2017 I recieve this message under
ASP NET CORE WebServer
Failed to initialize CoreCLR, HRESULT: 0x80131534
What I have tried:
Cleaning the solution, rebuilding etc
Restarting the computer
Trying to launch another application. (Same result)
Created a new application from scratch. Same result.
Repairing Visual Studio Community 2017. Same result.
Stopping/Closing IIS Express
My setup was working perfectly yesterday and suddenly is not.
Thank you for your time. I hope we can find a solution.
We finally found the issue! After logging on to the machine as a different user, we saw a warning that the main user had ignored initially. There was a 0 byte file in the root of the directory named "Program" with no file extension. It appears that this causes some sort of issue when VSIISExeLauncher.exe is invoked through Visual Studio. (Note it would work if executed from the command prompt). After deleting the file, everything worked!
We do not know how this file was placed there for certain, but suspect it was some sort of copy error when the user was pulling in files from his old hard drive.
I don't know if anyone else will come across this, but if so hopefully this helps!
Maybe you need install previous versions of .NET Core, isn't it? I installed here and it works now. I had only .NET Core 2.0 installed and I realized that applications with 1.1 stopped so when running. In Windows' event logs I've had the same error registered.
Try to change the IISExpress to IIS by creating new IIS profile and change the Lunch to IIS. It resolved my problem.
I have hit a very similar issue with ASP.net Core 2.0. I had copied my VS project to a new one, and I was getting this error message.
After doing some research, I was able to determine that the nlog.config file was not copied into the bin > Debug > net461 folder. Once I did this, I was able to run my application.
I found it by running dotnet run from the command line on my project where the csproj files live.
Had same issue yesterday (windows 10).
Solved it this way:
Update Microsoft.AspNetCore to latest (Nuget manager - 2.1.3)
Make sure the sdk also updated to latest version. if not, update it manually from Nuget console like this:
Install-Package Microsoft.NETCore.App -Version 2.1.3
Download and install latest ASP.NET Core/.NET Core: Runtime & Hosting Bundle
from here
Same problem with version 2.2. Reinstalling .NET Core SDK fixed the problem for us.
In my case, my project was setup as a website in IIS and the file "bin\IISSupport\VSIISExeLauncher.exe" was missing in the project's directory.
I simply selected "IIS" when debugging the project in Visual Studio 2019 and it generated the missing file. It also generated 2 text files (IISExeLauncherArgs.txt, pidfile.txt) in the IISSupport folder, made changes to my web.config file, and my project ran successfully.
After that I was able to access the local website that was setup in IIS without running it in Visual Studio.
After installing the ASP.NET and Web Tools 2015 (RC1 update 1) I get the following error within ASP.NET MVC 4 projects when opening *.cshtml files:
Object reference not set to instance of an object
I get the same error message even if I start a new ASP.NET MVC 4 project and try to open a *.cshtml file there.
I'm using Visual Studio 2015
Maybe this helps:
Delete the contents from the following folders:
C:\Users\%userprofile%\AppData\Local\Microsoft\VisualStudio
C:\Users\%userprofile%\AppData\Local\Microsoft\VSCommon
Sometimes, you need to go to:
[x64] C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE
[x86] C:\Program Files\Microsoft Visual Studio 14.0\Common7\IDE
and run devenv /resetuserdata.
Expect, that all of your user settings such as Visual Studio layout, linked Microsoft account or start page might disappear.
Delete %LocalAppData%\Microsoft\VisualStudio\14.0\ComponentModelCache and restart Visual Studio.
Alternatively, use the Clear MEF Component Cache extension.
For me,
I ended the process in Windows Task Manager: VsHub.exe.
Restarted Visual Studio.
After that, everything works like a charm again!
I solved it doing
run devenv /resetuserdata
in this path:
[x64] C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE
I assume that in x86 it works in this path:
[x86] C:\Program Files\Microsoft Visual Studio 14.0\Common7\IDE
It's recommended to try any or all of the following:
Restart Visual Studio
Try Running As Administrator (right-click Visual Studio and choose "Run As Administrator")
Check for any updates for Visual Studio (download and install them if any are available)
Try opening a different solution / project
If problems persist, you might try the following options:
Restart your local machine
Attempt to reset Visual Studio to System Defaults (this can be done from the options within Visual Studio)
Attempt to repair your Visual Studio installation
In the hopes it might narrow things down/help someone, I did an investigatory approach. For me, I initially moved the folder at C:\Users\{user}\AppData\Local\Microsoft\VisualStudio to My Documents and allowed Visual Studio to re-create it by re-launching it. This removed the errors. So I moved everything back, one-by-one, and restarted Visual Studio each time until I discovered the culprits. These folders were fine to move back in:
1033 (overwrote the auto-generated copy with old)
Designer (was in my old copy, not initially re-created when I re-launched VS, copied it back in)
Extensions (overwrote the auto-generated copy with old)
ImageLibrary (overwrote the auto-generated copy with old)
Notifications (overwrote the auto-generated copy with old)
STemplate (was in my old copy, not initially re-created when I re-launched VS, copied it back in)
VTC (was in my old copy, not initially re-created when I re-launched VS, copied it back in)
These files were fine to move back in/overwrite the auto-generated ones:
ApplicationPrivateSettings (was in my old copy, not initially re-created when I re-launched VS)
ApplicationPrivateSettings.lock (overwrote the auto-generated copy with old)
vspdmc.lock (overwrote the auto-generated copy with old)
These files were fine to move back in. Each was in my old copy, and not initially re-created when I re-launched VS:
.NETFramework,Version=v4.0,Set=Framework,Hash=C958D412.dat
.NETFramework,Version=v4.0,Set=RecentAssemblies,Hash=0.dat
.NETFramework,Version=v4.5,Set=Extensions,Hash=75EAE334.dat
.NETFramework,Version=v4.5,Set=Extensions,Hash=497525A2.dat
.NETFramework,Version=v4.5,Set=Framework,Hash=5AE9A175.dat
.NETFramework,Version=v4.5.2,Set=Extensions,Hash=24CEEB0D.dat
.NETFramework,Version=v4.5.2,Set=Extensions,Hash=72AE305.dat
.NETFramework,Version=v4.5.2,Set=Extensions,Hash=ADF899D7.dat
.NETFramework,Version=v4.5.2,Set=Framework,Hash=D8E943A2.dat
These caused problems - delete these files and re-launch VS to allow it to re-create them:
ComponentModelCache - When I overwrote this folder's contents with my old ones (4 files: MS.VS.Default.cache, .catalogs, .err, .external), this gave me all of the errors I had gotten before about not being able to load packages when loading my project, and the "object reference not set to an instance of an object" error when trying to close VS.
devenv.exe.config - same as ComponentModelCache
.NETFramework,Version=v4.0,Set=Extensions,Hash=6D09DECC.dat - causes error output from the JavaScript Language Service, complaining of missing js files
.NETFramework,Version=v4.0,Set=Extensions,Hash=9951BC03.dat - causes error output from the JavaScript Language Service, complaining of missing js files
.NETFramework,Version=v4.5.2,Set=RecentAssemblies,Hash=0.dat - causes error output from the JavaScript Language Service, complaining of missing js files
These are the errors from those last .NETFramework files (which I do not get if I do not add them back in):
01:10:11.7550: Referenced file 'C:\Program Files (x86)\Microsoft Visual Studio 14.0\JavaScript\References\libhelp.js' not found.
01:10:11.7550: Referenced file 'C:\Program Files (x86)\Microsoft Visual Studio 14.0\JavaScript\References\sitetypesWeb.js' not found.

I might just need to re-install/repair the JavaScript Language Service plug-in, so it might be un-related. But definitely devenv.exe.config and ComponentModelCache need to go to correct the "object reference not set to an instance of an object" error.
For me, ASP.NET 5 is not yet required, I removed update, and then reinstalled ASP.NET 4.5. It's a bit tricky:
Removed from control panel "Microsoft ASP.NET 5 RC1 Update1". After that, you will no longer open ASP.NET MVC projects
Then I changed the installation of "Microsoft Visual Studio Professional 2015", clicked "Modify", and selected "Microsoft Web Developer Tools"
No longer follow the notification of update in Visual Studio 2015!!!
After trying the top answer, I found that you must also restart the computer. The error may be part of a git issue as well where restarting your computer will reset.
I was getting an exception every time I tried to create a "new" project.
My solution was:
Go menu Tools → Extensions and Updates
Check the "Updates" link... There was an update to Microsoft ASP.NET and Web Tools. Install it.
That fixed it for me.
In my case (not necessarily be the solution for you, but it may be helpful for someone), the solution was:
Go menu Tools → Extensions and Updates
Select the Online tab from the right panel
Search for the words web tools, and then select Microsoft ASP.NET and Web Tools and install it.
In my case, this was missing from my computer because of a lot of repairing operations for Visual Studio.
I was getting similar error in VS2017 while trying to publish my solution to Azure.
This algorithm helped me to resolve it:
Close VS2017
Open C:\Users{your user name}\AppData\Local\Microsoft\VisualStudio\ folder
Rename 15.0_08edcd83 folder
Start VS
Publish works fine!
Note that this will remove your Visual Studio's recent files / projects from it's history and also linking to MS account.
This method is slightly different from the Top answer. Here you don't have to delete other folders except renaming abovementioned one.
I was getting this exception every time I created a "new" project.
My solution was:
Go menu Tools ? Extensions and Updates
Not check the "Updates" link...search "asp.net". There was an
update to Microsoft ASP.NET and Web Tools. Get it as
AspNetWebFrameworksTools2015_KB3137909.exe and install it.
That fixed it for me.
Unfortunately, I ran into another exception:
"Exception has been thrown by the target of an invocation"
I disabled the FIPS setting Enabled DWORD value to zero.
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\FipsAlgorithmPolicy]
Enabled=dword:00000000 And All fixed.
Goto windows+R and type %temp% and hit enter. delete the temp folder and files and then try opening the same
I have been fighting with this during the whole weekend. But it's pretty easy to do it. What I did was to click on repair rather than uninstall. After repairing, I clicked on restart directly. After that, everything is working perfectly.
You should try this, may be it can work also for you!!!
Restarting Visual Studio did it for me. On the next run, it displayed a "Scanning new and updated MEF components ..." and then it executed normally.
It seems to be related to Windows update somehow, although I don't have proof.
Delete bin and obj folders in all projects of that solution.
Seems like those folders were having old files generated by some older version of visual studio, which are not compatible with new version of visual studio.
The solution to the issue when i had this earlier today was that there was an additional
set of tags bolted on the end of my Web.config. Once removed the functionality returned.
Problem:
My VS 2015 was throwing up error after I installed SSDT. Whenever I clicked on Tools >> Extensions and Update it was throwing "Object reference not set to an instance of an object" error. When I tried to open a solution it threw some provider not set correctly.
Solution:
After many hours of research trying out all the solutions previously mentioned by others didn't solve my problem. Every time the error popup was pointing to check the ActivityLog.xml. But I was ignoring it. After hours of frustration I decided to read the error carefully and looked into ActivitLog.xml and found that it was looking for "Could not load file or assembly 'System.Collections.Immutable, Version=1.1.37.0". So I just started searching for this assembly and stumbled upon this link https://sergeytihon.com/2015/12/01/how-to-restore-viual-studio-2015-after-update-1-dependency-dance/
and followed the steps there, which fixed my issue.
Went into %LOCALAPPDATA%/Local\Microsoft\VisualStudio\14.0\devenv.exe.config and searched for "System.Collections.Immutable" and change newVersion from 1.1.36.0 to 1.1.37.0
Final config should look like this
<dependentAssembly>
<assemblyIdentity name="System.Collections.Immutable" publicKeyToken="b03f5f7f11d50a3a" culture="neutral"/>
<bindingRedirect oldVersion="1.0.27.0-1.1.65535.65535" newVersion="1.1.37.0"/>
</dependentAssembly>
Hi guys I got some code here thats buggin me.
ive managed to create a page and get it working on local host, but when i publish this to go live and nav to the web page it comes up with this error.
Could not load file or assembly 'DevExpress.Web.v11.1,
Version=11.1.4.0, Culture=neutral, PublicKeyToken=b88d1754d700e49a' or
one of its dependencies. The system cannot find the file specified.
(E:\web\shafteccom0\htdocs\Calendar\web.config line 44).
Ive tried adding all the references, and i mean all of the dev express ones, including ones i dont even need.
my project is a web project using visual studio 10, asp.net,C# & .Net version 3.5
ive also tried changing the .net version to 2.0, 3.0 and 4.0 but no luck.
If you need my code let me know and ill edit this.
Many thanks
That error means that the library that your application is looking for does not exist on the server you are deploying it to (or it cannot load it with the variables provided). Does the live server have the VS2010 references installed to it?
Just making sure: Are you sure your references set to "CopyLocal"?
I think DevEx installs it's assemblies in the GAC, so your local copy may be working but not when you deploy. Have you tried looking in the bin on the publish location to see if they are actually there?
