I'm getting the following error after installing VS2013:
Service Unavailable HTTP 503
The earlier version of IIS is working with an application pool ASP.Net 4.0. This uses the 4.0 framework. I believe the new version uses the 4.5.1 framework. So the application pool might get a conflict. So when I go through the IIS manager dashboard I noticed that the application pool is getting stopped automatically. So I manually restarted and tried again. Whenever the application starts this application pool get stopped automatically. I don't know why this happening?
Please could you help to fix this issue?
I am not quiet sure whether it works for you, but i had the similar problem once, registering the FrameWork with the IIS Manager resolved my problem.
Below are the commands to run depending on 64-bit/32-bit OS version installed in your system
%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -i
%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -i
Note:
1. Please remember to replace the "v4.0.30319" with your current version installed.
2. You should run the above commands as a Administrator(better if you logged in as a administrator).

I have web app running locally in IIS. App of Net Framework 4.7.2. When I tried "Attach to Process" for w3wp process in Visual studio I am unable to do so. Visual Studio is running under Administrator account. Things I tried:
Restart of IIS and VS in different sequence.
Setting "Enable 32-bit Applications" flag on app pool in IIS to true
Tried to run process monitor to see if there would be errors. Nope, no errors.
Tried manually set type of app in "Attach to" combobox to various types with same results. Types tried: Managed 4.x, with and without Compatibility mode, Managed(Native compilation), Native.
Tried Visual Studio repair - still having issue.
Created brand new web app .Net Framework 4.7.2, deployed it under IIS and tried to attach to the w3wp process and got same issue.
Things I noticed:
When I tried to attached to 64 version of the w3wp the type is "Managed Net 4, x64" and I am getting "Unable connect to the process" message with justification: VS must run as administrator. Funny thing: VS IS running as administrator.
When I turn 32-bit application flag on I am getting type as x86 and plain "Access denied". Even if restart IIS and try to access the app to start new w3wp process. I think it should be: "Managed Net 4, x86", but I am not 100% sure.
At this point I am out of ideas. Any help would greatly appreciated
UPDATE.
I noticed, when I turn on 32bit applications on app pool in IIS I am getting following error in Event Viewer:
"The description for Event ID 0 from source .NET Runtime cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer."
Turned out corrupted Avecto installation was the culprit. Reinstalling offending software resolved the issue. Live and learn. At least I lived.:)
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

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.
I have a Windows Server 2012 R2 & Visual Studio Professional 2012. now i use to develop an asp.net 4.5 mvc 4 web application without any problem. but now when i try to open the project i will get this error:-
if i click OK then this error:-
if i click OK the visual studio will stop working
so can anyone adivce what is going on ??
and here is how the Turn windows features on/off looks like:-
Now i did this modification, as i read on a post in the internet that deleting the cache might help. so i removed this folder:-
%LocalAppData%\Microsoft\VisualStudio\11.0\ComponentModelCache
then i tried to open the Visual Studio, and i got the same 2 errors, but the visual studio did not stop working, and i was able to modify the code i rebuild the project and run it.. so not sure what is going on ?
aspnet_regiis -i
Using the ASP.NET IIS Registration tool, you can perform tasks such as the following:
Register or remove the .NET Framework ASP.NET installation with IIS.
Create new ASP.NET application pools.
Display the status of all installed versions of ASP.NET.

Edit 1:-
dism /online /enable-feature /featurename:IIS-ASPNET45 /all
Try running this command
Edit 2:-
Try downloading and installing this update

In order to resolve this error you have to install related version of .Net framework in your system.
First install IIS if not installed.
Then run following command:
C:\Windows\Microsoft.NET\Framework\v4.0.30319> aspnet_regiis -i
OR (Depens on your OS)
C:\Windows\Microsoft.NET\Framework64\v4.0.30319> aspnet_regiis -i
And in IIS your site should run on pool with version like : .Net FrameWork v4.0.xxxxxx
Open your solution as an Administrator
Maybe this answer comes too late, but I tried the solution from #Sameer referring to this question stackoverflow.com/questions/13749138/asp-net-4-5-has-not-been-registered-on-the-web-server#13749209
aspnet_regiis -i
didn't work for me aswell, but this update fixed the problem for VS 2012
For Visual Studio 2012 you actually need to download an update to fix it from here: support.microsoft.com/en-us/kb/3002339 – Sameer Nov 16 '15 at 21:17
See if the computer has self updated to .NET 4.6 (due to Windows Update task).
In some situations, the installation of .NET 4.6 may impact on Visual Studio 2012.
In my case I had to upgrade my project to NET 4.6 to solve the problem.
In relation to IIS itself, I guess you may be forgotten some feature - as HTTP which I guess is necessary, even if you won't utilize it directly. Check all features and toogle OFF just those really optional (like FTP).
This reminds me of similar issues I have seen in the past and I strongly suspect it's an installation order related thing which ultimately boils down to the aspnet_regiis command which has been mentioned already (here's some more information on this topic: https://rockyprogress.wordpress.com/2011/09/06/iis-7-5-and-net-framework-4-installation-order-does-matter/).
You would generally want to install IIS first and then .NET afterwards. So I suggest you get rid of the .NET 4.5 installation again by using the "Turn Windows Features On/Off" screen and then later simply add it back in.
Please try below point
1) open Visual studio run as administration
2) Please host your site in IIS (Not on port like localhost:65389...)
3) Make sure about application pool (with framework 4.0)
4) run C:\Windows\Microsoft.NET\Framework\v4.0.30319> aspnet_regiis -i command
I've created an ASP WebForm application that requires "Enable 32-Bit Applications" to be set to true. When I set the site up in IIS I set "Enable 32-Bit Applications" true, but when I look at the Task Manager I'm not seeing the *32 next to the w3wp.exe process that starts up. And when I browse to the site I'm getting "Service Unavailable - HTTP Error 503. The service is unavailable." as the App Pool stops within IIS.
How can I force the w3wp.exe process to start in 32 bit mode?
EDIT- The machine in question is a 64-bit Windows Server 2012 R2 in case that matters
EDIT 2- I found a link to http://www.manasbhardwaj.net/running-32-bit-web-application-iis-8/ Which references issues wile Running Sharepoint 2013, Which is running on the web server. It applied the changes, and now when I run the site I get a configuration Error regarding framework versions.
I find it odd b/c the app pool still is not showing the *32 next to it, but it didn't crash when starting the site.
I'm going to ensure the latest .NET framework is installed now.
EDIT 3- Looks like I need to run a couple of updates on the machine in order to install the latest .NET framework. The .NET framework my site uses is 4.6.1, Is this version Stable enough to run on a Live WebServer running SharePoint 2013?
I'm trying to deploy an ASP.Net application I developed to a Windows Server 2003 System but I get a error message when running the Site.
The first thing is that I get a Null Reference exception when I want to access my custom configuration section. So I figured that maybe the System.Configuration Assembly might not be installed. However I removed the reference and included the database directly into code to see if it works without.
But now I'm getting another error that a third party server control is not recognized.
Error Message: Server label
"trirand:JQGrid" unknown.
The same application runs just fine on my XP machine with IIS 6 installed so I wonder if I'm missing some installation. This is the first ASP.Net Application on that machine as before there were only ASP tools. I think that the .Net Framework 3.5 SP1 is installed but I'm not sure. Another question is if the ASP.Net is integrated into the .Net Framework of if I need a different install package.
Update:
I experienced a weird behaviour: I added the obviously wrong element <asdf> to the web.config file. On my development machine that gave me the expected error, but on the server nothing happened at all. So it seems like it some does not recognize my web.config file.
You need to check if the windows server system is loaded with the software your application required.
The folder v3.5 should be there in the following location.
C:\WINDOWS\Microsoft.NET\Framework\v3.5
Also you need to check if asp.net is installed on the system, if you are not sure then do install it, installing it if it is already there have no side effects.
To install asp.net type the following commands in DOS prompt.
cd C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727
// then
aspnet_regiis.exe -i
Then also, confirm in IIS that correct version of asp.net is selected for your website.
To check; go to your website properties in IIS
then select ASP.NET tab then check ASP.NET version it should be 2.0.50727 for websites below .net version 4.0
Good Luck!
