'Azure Linux Web App Service - System.IO.IOException: Readonly File Error
The web app already running on .NET Core 3.1 LTS with IIS (windows server 2019)
Recently, I deployed as an Azure Web App Service but I encountered a file write error.
The application trying to create a new file for some business requirement.
Error message; System.IO.IOException: Read-only file system
Has anyone encountered this problem on Azure Linux Web App?
Solved: The Azure Linux Web App Service doesn't support directly file uploading to a regular folder under the wwwRoot. If you can running on the linux web app service, you need to use blob / storage etc..

Make sure that you have provided correct path whether it is any storage account or local storage where you are getting files. Also, if possible, elaborate your questions with full error trace, path you are using to access.
