Hello - I am using Radzen 2.62.4 and am getting a HTTP Error 500.30 - ASP.NET Core app failed to start error after Radzen says the deploy was successful. I previously had deployed a couple different Radzen projects to Azure using Azure SQL, including a previous version of this project. I also created a new project and inferred the same Azure database to create new crud pages, and it deploys just fine. My application also runs perfectly via Radzen and Visual Studio.
Any ideas? Error and other info is below.
HTTP Error 500.30 - ASP.NET Core app failed to start
Common solutions to this issue:
The app failed to start
The app started but then stopped
The app started but threw an exception during startup
Troubleshooting steps:
Check the system event log for error messages
Enable logging the application process' stdout messages
Attach a debugger to the application process and inspect

I followed this link to troubleshoot, and get the following error.

I confirmed that I am running .NET 5, and since my other projects deploy just fine, I dont think the issue is with the Azure app service. I did delete and re-create it a couple of times while troubleshooting though.
Yes, I just realized that this is definitely old suggestion related to assemblies but not for NuGet packages. I'm afraid that I've never seen such error before and I don't have any other suggestions. Try to deploy the application to ZIP from Radzen, extract the zip locally and make sure it's running properly with dotnet appname.dll and after that copy manually to your Azure the ZIP content.
I just deployed to zip and ran it and I am getting the same error. I ended up telling the Radzen package to update, so now it says 3.9.7.0. I will need to pick up trying to deploy to Azure manually in the morning, but I suspect it wont work if it wont run locally.
dotnet OrderBahn.dll

Got it working by using the publish function in Visual Studio and under the Publish settings selecting the "Remove additional files at destination". Well, I guess I cant say with 100% certainly since I hadnt tried publishing in Visual Studio yet. Previously I was only using the deploy in Radzen.
I then followed these instructions to deploy via the Kudu UI by zipping up the files from the VS publishing and dragging into the interface. I deleted all the files first in Azure.
Figured it would be helpful in case someone else has this issue. I dont have time this week to circle back and isolate it further, but I do want to understand what the actual issue was and will post back if I find anything.
