I have got this error, but hardly could find the solution after 2 times reinstalling my IDE and even I installed 'All in One runtimes' but it couldn't help since I think the problem originally started after I changed few settings in windows defender setting and then tried to reset them.
But sure others have reported this problem and had no idea of what had happend all of a sudden to get following error when trying to run the application:
JetBrains IDE Error on start : The application was unable to start correctly (0xc000007b)
The application was unable to start correctly (0xc000007b)
*1 - which in my case was Phpstorm64.exe running on windows 10
I just felt there is no 'easy to find' solution for this occurring problem, so I decided to post it on Stackoverflow
In my case this was helpful and worked for me:
just disable ASLR (Address space layout randomization) from windows defender
in Windows 10 you should follow these steps:
open Settings (just right-click on windows start and choose
settings)
search for 'Windows Defender Settings' or just go to 'Update & Security' > 'Windows Security'
then open 'App & browser control', in the new opened window scroll down to the end to find 'Exploit protection settings', click
that
sort of settings will be shown and you can change the default settings. to create an exception you should click "Program settings"
(which doesn't seem to be a button,but it is!)
click 'add program to customize', in the dialog enter your ide name.exe (you can easily find it by clicking 'open file location' on
shortcut of the application)
in my case the application name was 'phpstorm64.exe'
next you have to look for 'force randomization for images (Mandatory ASLR)' check the 'override system settings' and switch it off and apply settings.
I'm not sure if it's needed,but turning off 'Randomize memory allocations (Bottom-up ASLR)' stated to work for others
I would appreciate if you help to get a complete solution for this problem , thanks
The crash is probably caused by ASLR Windows feature, the relevant ticket in the JetBrains issue tracker: IDEA-184029
Please check if the following workaround:
Turn the feature off globally or for a specific executable path https://learn.microsoft.com/en-us/microsoft-365/security/defender-endpoint/customize-exploit-protection

We know a random port number is assigned to a web application in Visual Studio. It works fine in my office desktop. But when I pull the code onto my laptop (from VisualStudio.com) and run the web app. I got a message, saying,
The specified port is in use
Port 10360 is already being used by another application.
Recommendations
Try switching to port other than 10360 and higher than 1024.
Stop the application that is using port 10360.
I can fix it using Recommendation #1 by changing the port into something else like 13333. But I am very curious what happened to port 10360. How can I check what application is using port 10360? How can I stop that application?
I had a similar issue running Visual Studio 2019 on Windows 10.
Some solutions that worked for others seemed to include:
Changing the application port number.
Have Visual studio automatically assign a port number each time the application start.
Restart Visual Studio
Restart the computer.
Unfortunately, none of these solutions worked for me, assigning another port number did work but was not an acceptable solution as it was important for my application to run on a specified port.
The Solution
First I ran the command:
netsh http add iplisten ipaddress=::
from an elevated command-line process. This solved the initial error, when attempting to run the application I no longer got the "port in use" error, instead, I now got an error stating the application was unable to bind to the port because administrative privileges were required. (although I was running Visual Studio as administrator)
The second error was caused by Hyper-V that adds ports to the Port Exclusion Range, the port my application uses was in one of these exclusion ranges.
You can view these ports by running the following command: netsh interface ipv4 show excludedportrange protocol=tcp
To solve this second error:
Disable Hyper-V: Control Panel-> Programs and Features-> Turn Windows features on or off. Untick Hyper-V
Restart the computer.
Add the port you are using to the port exclusion range: netsh int ipv4 add excludedportrange protocol=tcp startport=50403 numberofports=1 store=persistent
Reenable Hyper-V
Restart the computer
From here everything worked perfectly.
i solve the problem this way...
File -> Open -> Web Site...
After that select Local IIS under IIS Express Site
remove the unwanted project.
hope this help.
change it in solution (right Click) -> property -> web tab
Click Create Virtual Directory (in front of project Url textbox)
This was haunting me for over a year!
For me,
no website was running iin IIS Express
nothing was using the port as determined by running: netstat -ano at the command line.
The solution was to run
netsh http add iplisten ipaddress=::
from the command line.

SIMPLE SOLUTION THAT WORKED FOR ME: (Credits to combination of other's answers)
**My System Info:**
Windows 10 build : 1809
IIS Version : 10.0.17763.1
Hyper-V : Enabled
Docker : Installed - 2.3.0.2 (45183)
Check for blocked ports range in CMD (admin)
>> netsh interface ipv4 show excludedportrange protocol=tcp
(Sample output):
Protocol tcp Port Exclusion Ranges
Start Port End Port
---------- --------
49696 49795 (SEE HERE, 49796 to 49895 is not blocked)
49896 49995
... list goes on ...
Open Visual Studio and Navigate to > Project > Properties > Web > Servers > Project Url
Use the Port that is not blocked.
(Sample port):
http://localhost:49796/
Restart Visual Studio (if required)
Have a coffee and share love. (required) :)
I had the same problem, but no proccess appeared neither in netstat nor in resmon.
What solved the problem for me was closing all the open browser windows.
You're looking for netstat.
Open an administrative command shell and run
netstat -aob
And look for port 10360. It'll show you what executable opened the port and what PID to look up in Task Manager. (Actually, run netstat -? in an unprivileged shell first, because I don't approve of blindly running anything you don't understand, especially in a privileged context.)
Here's what the switches do:
-a shows all connections or open ports, not just active ones - the port you want is probably listening, not active.
-o shows the owning PID of the connection or port, so you can find the process in Task Manager's Processes tab. (You might need to add the PID column in Task Manager. View->Select Columns)
-b shows the binary involved in opening the connection or port. This is the one that requires elevated access.
The cause of this issue in my own case is a bit different. Everything was working fine until I started docker to do some other stuff. Starting docker, in one way or the other, added some new ranges of ports to the Port Exclusion Ranges. What to do:
Open command prompt (As an administrator)
run: netsh interface ipv4 show excludedportrange protocol=tcp (You should see the port your application is using in the excluded port ranges)
run: net stop winnat
run: netsh interface ipv4 show excludedportrange protocol=tcp (by this time, the Administered port exclusions ranges should reduce)
run net start winnat.
If the problem was caused by Windows NAT Driver (winnat), then you should be good by now.
Close the VS
Start again - right click and run as admin
Run your project again.
Running visual studio in administrative mode solved my issue
Delete the .sln file, if you have one.
Open the file C:\Users\NN\Documents\IISExpress\config\applicationhost.config
Locate the problematic site in configuration/system.applicationHost/sites and delete the whole site section.
"Open Web Site.." from Visual Studio and the project will be given a random new port.
For me the "The specified port is in use" error is usually fixed (well actually worked arround) by stopping the "Internet Connection Sharing (ICS)" (SharedAccess) and the "World Wide Web Publishing Service" (W3SVC) service.
After the project / ISS Express is started the stopped services can be started again without issues.
Whenever i receive the error the port (in the 50000 range) is definitely not in use (checked with netstat & tcpview).
It would be nice if Microsoft did some integration testing of Visual Studio / IIS Express along side with HyperV and the "normal" IIS Service OR gave some guidance on which port ranges to use for VS / IIS Express (and which ports to avoid).
Visual studio 2015
Close all the files you have open inside Visual studio.
Then close application and exit Visual Studio.
Open Visual Studio and it should successfully run.
I hope this helps.
netstat didn't show anything already using the port
netstat -ano | findstr <your port number> showed nothing for me. I found out that port was excluded using this command to see what ranges are reserved by something else:
netsh interface ipv4 show excludedportrange protocol=tcp
You can try to unblock the range from the start port for a number of ports (need Command Prompt with Administrator):
netsh int ip delete excludedportrange protocol=tcp numberofports=<number of ports> startport=<start port>
However, in my case I couldn't unblock the range, I just got "Access is denied", so I ended up having to pick another port for my site.
My original solution: The only thing that worked was deleting the .vs folder in the solution folder. (I've since found you can just delete the .vs/config/applicationhost.config instead to avoid losing so many settings).
If netstat doesn't show anything, try a reboot.
For me, nothing appeared in netstat for my port. I tried closing Google Chrome browser windows as #Clangon and #J.T. Taylor suggested, but to no avail.
In the end a system reboot worked, however, so I can only assume that something else was secretly holding the port open. Or perhaps it just took longer than I was prepared to wait for the ports to be released after Chrome shut down.
For me, close all application and restart the computer.
When window start, Open Visual studio first, then open browser and click run(F5).
Now it works. I don't know why.
Open Task Manager and Just Close all processes of 'IIS Express System Tray' and 'IIS Express Worker Process' and Re-run the Project
For me, the Google Chrome browser was the process which was using the port. Even after I closed Chrome, I found that the process still persisted (I allow Chrome to "run in background" so that I can receive desktop notifications). I went into Task Manager, and killed the Chrome browser process, and then started my web application, it worked like a charm.
Open your csproj with for example Notepad ++ and scroll down to DevelopmentServerPort. Change it to something else as long as it's above 1024 like rekommended (so for example 22312). Also change the IISUrl to http://localhost:22312/. Save your changes and restart the project.
In my case there was no application using specified port and elevated running of Visual Studio didn't help either.
What worked for me is to reinstall IIS Express and than restart computer.
For me it was an orphaned VBCSCompiler task from a previous run, that didn't shut down and was somehow interfering. Killing that task solved it.
https://developercommunity.visualstudio.com/content/problem/31482/vbcscompiler-does-not-shut-down.html
You need to configre this parameter by running the following in the administrative command prompt:
netsh http add iplisten ipaddress=::
click on the notification present on bottom of the task bar if you receiving the error like port in use then select the iiss icon right click then click on exit ,it work like charm for me
I had same error showing up. I had my web service set as an application in IIS and I fixed it by:
Right-click on my WebService project inside my solution > Properties > Web > Under 'Servers' change from IIS Express to Local IIS (it will automatically create a Virtual Directory which is what you want)
When Port xxxx is already being used, there's always a PID (Process Id) elaborated with the error. Simply go to the task manager on the machine you are running the application, click on details, and you will identify what the other application is. You can then decide whether you want to end that process or not
Just to add to this, I had the full IIS feature turned on for one of my machines and it seemed to cause this to happen intermittently.
I also got random complaints about needing Admin rights to bind sites after a while, I assume that somehow it was looking at the full IIS config (Which does require admin as it's not a per-user file).
If you are stuck and nothing else is helping (and you don't want to just choose another port) then check you have removed this if it is present.
FWIW, I tried tons of these options and I didn't get anywhere. Then I realized I had installed VMWare Player just before the issue started. I uninstalled it, and this error went away.
I'm sure there's some way to make them coexist, but I don't really need Player so I just removed it. If you've tried all kinds of stuff and it's not working consider looking through any programs you've installed recently (especially those that deal with network adapters?) and see if that gets you anywhere.
In Visual Studio 2017, select Project/Properties and then select the Web option. In the IIS section next to the default project URL click Create Virtual Directory. This solved the problem for me. I think in my case the default project Virtual Directory had been corrupted in some way following a debugging session.
For me only thing worked is removing the element containing my application name, path and binding info under
</system.applicationHost> element in
applicationhost file.
To be found under C:\Users\yourUsername\Documents\IISExpress\config
Closed the the solution , deleted the bad site element , save the applicationhost file and close.
Reopen the application/Website from Visual studio using Admin rights - Rebuilt and Run. Voila... A new port is auto assigned to your application which solves the purpose.
Can also be verified without running-- check the Properties window for the solution and URL will have new port number.
In my case I got also this issue from my ASP Core 3.1 projets.
I thing that for some reason visual studio ignore the IP/Port setting in the project property and start it on 5000 and 5001. I discovered this while attempting to start my Core 3.1 projects from prompt using dotnet run
And this post helped me
How to specify the port an ASP.NET Core application is hosted on?
It suggest to
Specify the port in the appsettings.json or maybe appsettings.development.json. (see lower)
Close Visual Studio
Delete /.vs, /bin, /obj folders
Restart Visual Studio.
appsettings.json / appsettings.development.json content

I have two machines one running Win 2000 and one running Win XP both with VSC++ 6. I created an application using MFC on the Win XP machine (local) and successfully used the Win2000 machine (remote) as the target for debugging. The code was in a shared drive on the Win2000 machine. This setup worked well, just like in the movies!
However, I now wish to use my Win2000 machine as a development machine again and I find I can not. When attempting to execute a natively compiled application on this machine, I get a dialog with the title of "Remote Execution Path And Filename" asking me for same. When dialog is cancelled as the program that is attempting to execute is not remote, the program terminates without error.
Extra info!
On the WinXP machine, VSC++, under the Build menu->Debugger Remote Connection->Remote Connection Dialog->the "Connection:" list box has two entries 'Local' and 'Network', on the Win2000 machine the 'Local' entry is not present, only the entry for 'Network'.
How do I get back my 'Local' entry on what used to be my target machine (Win2000)? Will this solve my lack of execution ability from VSC++?
Right click on the project in the Solution Explorer window and bring up the project's properties. Under "Configuration Properties" you'll see Debugging. Change the "Debugger to launch" combo box from "Remote Windows Debugger" to "Local Windows Debugger".
You'll need to do this for any configurations you debug. If you wish you can set the Configuration combo box to "All Configurations" and change them all at once.
