Solution is:

I try exclude almost everything in»Exclusion» section of Virus & threat protection setting of Windows Defender, but solve my problem is turn Off «Real-time protection».

If anybody know what exactly need to exclude, I am glad to know it.

I’m seeing this error in a pop-up window when attempting to run/debug my web project from Visual Studio

The following error occurred when trying to configure IIS Express. Opening and creating websites on iis requires running visual studio under an administrator account

This happened completely out of the blue. One second I was working as normal, regularly going in and out of debug in my browser, then this error pops up. It happens when attempting to run any web project, and it doesn’t matter if it’s in debug, release mode or what.

Stuff I’ve tried:

Run Visual Studio as Administrator

Uninstall/Reinstall IIS Express (via «Turn Windows Features On or Off» in Control Panel)

Update Visual Studio

Delete project’s .vs folder

But still the error persists.

Is there anything else I can reinstall, update or otherwise check?

Thanks.

Solved it by going through a day of hell, and to be honest the ‘solution’ was very brute force…

TL;DR: Fully deleting and reinstalling Visual Studio seemed to do the trick.

Since the usual methods weren’t working, I tried a full reinstall of Visual Studio. That didn’t help. I then tried a System Restore. That made everything far worse, with my project showing about 500 error messages!

I then undid the System Restore, completely deleted all traces of Visual Studio from my computer, reinstalled everything, then tried VS2019 preview edition, tried 2017 edition again, uninstalled and reinstalled NetCore 2.0, 2.1, 2.2… all just to get around the minefield of error messages I’d created for myself.

In the end I just needed to do a full NuGet clear and restore then run dotnet restore --force in the NPM console, after which all those error messages were gone. As well as this, the original IIS Administrator error was gone too, presumably fixed via the original reinstall of Visual Studio.

Lost a whole day to this quagmire.

Hello,

Trying with admin account didn’t work.
Trying on different machine worked but still need to make it work on my main development machine.

I tried updating the .Net Framework on my machine to .NET Framework 4.6.2 and then to .NET Framework 4.7
And also added some attributes to catch the exception details.

At first I got this message :

Managed Debugging Assistant ‘FatalExecutionEngineError’ : ‘The runtime has encountered a fatal error. The address of the error was at 0x70c5f13b, on thread 0x2338. The error code is 0xc0000005. This error may be a bug in the CLR or in the unsafe or non-verifiable portions of user code. Common sources of this bug include user marshaling errors for COM-interop or PInvoke, which may corrupt the stack.’

Now I am getting this message (copied from Visual Studio debugger)

e.Message

One or more errors occurred.

e.StackTrace

Please advise,

I still not able to use your product since more the a month of trying every day .., it’s becoming a bit urgent for me to getting work,

Thank you for your assistance

I am trying to load existing c# web applications and getting below errors while loading any web project:

Creation of the virtual directory http://localhost:/ failed with the
error: You do not have permission to access the IIS configuration
file. Opening and creating web sites on IIS requires running Visual
Studio under an Administrator account.. You will need to manually
create this virtual directory in IIS before you can open this
project.

The following error occurred when trying to configure IIS Express for
project xxx.WebApi. You do not have permission to access the IIS
configuration file. Opening and creating web sites on IIS requires
running Visual Studio under an Administrator account.

I tried following, but in vain:

Running VS 2017 pro as an administrator.
I ensured that I have access to %systemroot%System32inetsrv and C:WindowsSystem32inetsrvConfig folders.
I have installed all IIS compatibility windows features through control panel.
Restarted IIS manager.
Created virtual directories.
Changed registry path of HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionExplorerShell FoldersPersonal from u: to C:UsersMyUserDocuments.
Uninstalled IIS Express 10.0 from control panel and reinstalled it through VS2017 installer by clicking – Individual components – cloud, database server – IIS Express.
Repaired VS 2017.
Got admin access on machine.
Created new empty web project but getting same error while new console app runs without errors.
Restarted machine after every installation related change.

All the solutions tried are mentioned on stackoverflow but are not working for me. Is there something trivial that I am missing? Please guide me to crack these IIS errors.

I was able to solve this issue doing the following:

1- Go to C:WindowsSystem32inetsrv and double click on directory config and accept the warning message.

2- Go to C:WindowsSystem32inetsrvconfig directory and double click on directory Export and accept the warning message.

Then you will be able to run the app in your local IIS without being an administrator. You can follow the path in the given Image.

This solved the problem for me with Visual Studio 2017, .Net Core 2.2 and IIS Express 10.

You need to ensure devenv.exe has sufficient permissions. You can find it at:

C:Program Files OR Program Files (x86)Microsoft Visual Studio nn.nCommon7IDE

Right click on the exe, select Properties, Security. I gave Administrators full control as I’m running VS under admin.

My Simple solution was to right click on Visual Studio and click Run as Administrator. But a solution above tells you how to have Visual Studio always run without having to run as an administrator.

VS2017 RC — The following error occurred when trying to configure IIS Express

answered Jan 26, 2021 at 5:01

The issue for me was caused when I modified my project to override application root URL. After a push/merge and new branch my project would not load any longer. reverted the changes and all is well again.

answered Jul 20, 2022 at 13:26

Open an elevated command prompt and enter the following command to substitute a drive path for U drive.

c:windows:system32> Subst u: C:UsersMyUserDocuments

I had replaced ‘U:’ path in registry with ‘C:UsersMyUserDocuments’ previously. I think that was not sufficient. Some references of u: might have been hindering IIS.
The total substitute command must have replaced all references and the IIS config error got resolved. Hopefully, now I’ll be able to load my web apps.

I had the same issue, but instead of the workarounds (such as first double-clicking certain directories each time or running the security risk of always having to always run my VS as administrator), was able to permanently resolve the issue by deleting the «ProjectName.csproj.user» file and that fixed it. I guess there was some incompatible setting in the user file that VS couldn’t deal with.

For older versions, change the option from IIS to your solution name, before clicking on the green play like run button, to build and run the application.

answered Dec 1, 2021 at 8:50

We resolved this by removing the project and adding it back.

If you’re used to run your Visual Studio via shortcut with ‘Run as administrator’ checkbox marked, double check it is indeed still selected. For some reason mine had unchecked itself resulting in inability to load an IIS project. I was 100% sure my VS had these administrative privileges as usual, which made me try all the Internet proposed solutions except for the most obvious one.

Microsoft Visual Studio

The following error occurred when trying to configure IIS Express for project SelfServe-Core. Filename: ?
C:UserschkollaDocumentsVisual Studio 2017ProjectsManagementSelfServe-Core.vsconfigapplicationhost.config

Error: Cannot write configuration file

Do anyone has faced this issue

anyone still around, guess you are busy working out the bugz

up to anything interesting?

I have been in a cave trying to put together some tutorials

I suck at making videos….

I haven’t tried making videos

but I made docker work inside a VM,

I write long README .md files

cause I am using a clean VM for filing

is wcf coming to .net core?

makes my life a LOT harder

is the asp.net core sockets a wcf successor?

I wanted a nice modern replacement, not a copy

now there is ZERO incentive to remove WCF

in a lot of projects … but meh

I have been playing with gitpitch to make my tutorial

after your tweet @davidfowl

how do you know wcf is coming do .net core?

the client part is done accept for net.tcp

but that is being worked on

to be fair it will help me out in the short term, I have a number of services that can’t be moved or created because they need data out of WCF only services

is there a planning for the server part?

I haven’t found one either

this week was Red Hat Summit

Scott Hunter was at Summit

I have issues of my own (releases next week) gonna be busy

I don’t think there is a recording available yet
