Azure App service not allowing to Edit the files present in wwwroot folder: "Access to the path 'D:\home\site\wwwroot\wwwroot/templates/abc.pdf' is denied"

Question

I am facing one weird issue.
I have created one .net core application that overwrites the pdf file available in root location of application; and this is working fine locally.
but when i publish on Azure App service and run, use to get error

Access to the path 'D:\home\site\wwwroot\wwwroot\templates\abc.pptx' is denied.

Here is the code, i am using in Azure App Service

var masterFile = Path.Combine(Directory.GetCurrentDirectory(), "wwwroot\templates\","MasterTemplate.pptx");
var dummyFile = Path.Combine(Directory.GetCurrentDirectory(), "wwwroot\templates\", "abc.pptx");

System.IO.File.Copy(masterFile , dummyFile, true);

=====================
Please suggest if you know any solution around...

Hi @Saleem Baig ,

Thanks for your patience! Based on this SO thread you can try changing this

App Setting Key

WEBSITE_RUN_FROM_PACKAGE = 1 to 0  

"This setting makes wwwroot as a read-only file system. With Run From Package, this is strictly enforced as the wwwroot folder becomes read-only"
