Windows 11 ARM - Visual studio IIS Express crash

I have a Windows 11 Pro(Version 22H2) 64bit ARM VM created with Parallels (Version 18.0.1 (53056))
I installed net core 5 and 6 for ARM (SDK and hosting bundle)
I created a new net core web application but when I start debug IIS Express didn't start and event viewer error is:

The Module DLL 'C:\Program Files\IIS\Asp.Net Core Module\V2\aspnetcorev2.dll' could not be loaded due to a configuration problem. The current configuration only supports loading images built for a AMD64 processor architecture

I tried to change app URL port number, delete .vs folder and IIS debug instead of IIS Express

Always the same error

In the past I installed Windows 11 ARM Insider Preview and IIS Express (with the same VS project now I have the problem)

 

Same here, I have exactly the same issue, "iis express" tried to run .net 4.8.1 project, VS always complain with Unable to launch IIS Express Web Server.
Try to run "iisexpress.exe /trace:error" always said error loading global modules. at the end using full local IIS which is not ideal.

 

PS C:\Program Files\IIS Express> .\iisexpress.exe /trace:error

I'm having the exact same issue, also with a .NET Framework 4.8.1 app built in Visual Studio 2022 ARM on Windows 11 ARM. My app builds, but trying to view it locally in the browser results in a 503 and the app pool crashes with the same error as above: "The Module DLL 'C:\Program Files\IIS\Asp.Net Core Module\V2\aspnetcorev2.dll' could not be loaded due to a configuration problem. The current configuration only supports loading images built for a AMD64 processor architecture."

I used Microsoft's Error Lookup Tool to get more details about the exact error, and it reported the following (screenshot attached as well):

.NET Framework 4.8.1 is supposed to fully support ARM, so I don't know why this doesn't work.

If anyone can figure out a fix, I will seriously write you a check! This one issue is preventing me from using my M1 MacBook Pro for work since I need to be able to build and run .NET Framework 4 apps.

 

I have the same issue but it seems to be related to microsoft not parallels ...
Did you found a workaround ?

 

Oh man! Any chance you can provide step-by-step directions how to set that up? I'm not familiar with Docker at all.

 

Someone posted a supposed workaround for this issue using Docker, but then deleted it for some reason (that's what I was referring to in my previous post on February 9). Does anyone else know of a workaround?

 

Also have the same error since February, i run Framework 4.8 site on IIS and ever since i installed the dotnet-hosting exe (also tried the latest dotnet-hosting-7.0.5-win.exe ) - whenever i try to access my site i get the "HTTP Error 503. The service is unavailable." error - the application pool stops the in the event viewer i get the error:

"The Module DLL 'C:\Program Files (x86)\IIS\Asp.Net Core Module\V2\aspnetcorev2.dll' could not be loaded due to a configuration problem. The current configuration only supports loading images built for a x86 processor architecture. The data field contains the error number. To learn more about this issue, including how to troubleshooting this kind of processor architecture mismatch error, see http://go.microsoft.com/fwlink/?LinkId=29349."

i installed the dotnet-hosting module because we are in a transition period to .net7, i'm using an M1 Max Mac
Trying to run the .net7 web application also result in the same error.
the only way to succeed in running my FW4.8 site is by uninstalling dotnet-hosting-7.0.5-win.exe

 

Had the same issue, guys, but for me downgrading the Visual Studio did the trick.
I use VS 2019 v16.11.26 form here: https://learn.microsoft.com/en-us/visualstudio/releases/2019/history#installing-an-earlier-release.
(for me it does not work with newer versions)
Also, make sure to delete .vs folder from the solution.

 

Try installing IIS via the Windows Features. Then update Visual Studio to use Local IIS instead of IIS Express

 

@AviP , holy cow, that did the trick! I didn't even have to uninstall url-rewrite, I just removed the <rewrite> section from my web.config and then set both "Enable 32-Bit Applications" and "Enable Emulation on ARM64" to false like you said, and it worked!

I've only tested this with one project so far, so I'll have to see if my others work the same way, but: this is the first time since I bought my M1 MacBook Pro almost a year ago that I've been able to successfully run a .NET Framework 4 app! This is a huge deal for me since it means I won't have to bounce back and forth between a separate Intel Mac and can have everything I need on one system again.

Thank you, thank you, thank you! Where should I address your check?

 

I encounter the same problem. How do you uninstall url-rewrite on iis express??

Further, I don't have these two settings in VS2022, as there are no application pools in IIS Express to configure. Where can I set these settings "Enable Emulation on ARM64" and "Enable 32-bit-Applications" for IIS Express?

My app runs on IIS, but not on IIS Express.
