Unable to resolve 500.30 error in simple web application
Error
I just created a new Razor Pages website. It's simple and only has a couple of page. But the site is failing with the following message.
Event Viewer
I see the event viewer is reporting errors.
Application '/LM/W3SVC/7/ROOT' with physical root 'C:\inetpub\wwwroot\scwebgroup.com' hit unexpected managed exception, exception code = '0xe0434352'. Please check the stderr logs for more information.
Application '/LM/W3SVC/7/ROOT' with physical root 'C:\inetpub\wwwroot\scwebgroup.com' failed to load coreclr. Exception message: CLR worker thread exited prematurely
Error Logging
I set stdoutLogEnabled to true in web.config.

But I can find no log folder or any log files.
Running from the Command Line
I read you can try running the application from the command line and any errors might be shown, so I tried that. But when I ran the application, no errors were reported. It appeared to run correctly.
Target Version of .NET
My app is targeting .NET 6.0 and I have other applications that target .NET 6.0 on this same server. So I know this version of .NET is installed.
Summary
The application runs fine when I run it within Visual Studio.
The new application does not access any database.
I'm out of ideas. Can anyone offer other things to try here?
When deploying, be sure to set the correct Target Runtime. If you are running on Windows Server, this will likely be win-x64.
If you get this wrong, the application will fail to load, and will give errors similar to what you're reporting.
