Hi,
I just have deployed a .NET 6 application to an Azure App Service, but right after the deployment I have the following error message in the Log Stream:

The environment:
- Private endpoint configured
- VNET Route All configured
- All traffics are routed via Azure Firewall (there are no any outgoing packets - I thought maybe it wanted to download .NET 6)
- Custom DNS servers configured for the app service
- Base system: Linux
- Project: .NET 6 LTS
Any idea?
Thanks!

2022-03-11T12:42:46.25+00:00 Hi,
I could solve the problem on the following way:
- Remove private endpoint, vnet routing and custom DNS settings
- Publish one application via direct internet
- Test application (must work)
- Reconfigure private endpoint
- Test it from internal
It seems there is some issue with the app service if the private endpoint is turned on before the 1st deployment.

Thanks for bringing this to our attention.
Based on this blog post announcement .NET 6 now generally available in App Service.
I see two different errors from what you posted:
Could not execute because the application was not found or a compatible .NET SDK is not installed.
Container myappservice-non-prod-aps_0_9a02a720 didn't respond to HTTP pings on port: 8080, failing site start. See container logs for debugging.How did you install .NET6? Can you try removing the private endpoint if possible and let us know what happens?
You can try using the WEBSITES_PORT app setting with a value of "8080" to expose that port and then restart your appBest,

2022-03-11T20:00:14.407+00:00 Hi,
After I removed the private endpoint and run a deployment, everything worked fine.
However, if I installed private endpoint prior to perform any deployments, I am always received the error message you see above.
It seems the App service with .NET6 is wrongly configured because it is not installing .net 6 by default.
Thanks!
Gabor
