startup.cs

public void Configure(ILoggerFactory loggerFactory, IApplicationBuilder app, IHostingEnvironment env)

How to solve this Exception ?

It looks like your app pool doesn't have enough permissions. — P.N.

Most likely the app pool identity doesn't have access to that path. Try giving it access to c:\inetpub (and all of its sub-directories). If the app pool runs as an impersonated user, you should pick a different folder than inetpub. — Arian Motamedi

Right click on the wwwroot folder -> Properties -> Security tab -> Click at Edit button -> Enter IIS AppPool\DefaultAppPool user -> Click at Check names -> OK -> Then give it Write permission.

This worked for me except the user name was called IIS IUSRS, which I found listed under the Advanced button in the Add user menu.

Isnt it risky to give eveyrthing write permission?

It's not everything. It's only the user of your app's pool in the IIS. The rest of it should be controlled by your app.

Work fine...

string fileName = file_name+".pdf";

           string files = System.IO.Path.Combine("pdf/") + fileName;
            if (!System.IO.File.Exists(files))
            {
                return RedirectToAction("index", new { message = "File Not Found" });

            }
            else
            {

                byte[] fileBytes = System.IO.File.ReadAllBytes(files);
                return File(fileBytes, System.Net.Mime.MediaTypeNames.Application.Octet, files);

            }
