Azure App Service configuration settings (environment variable) does not work

Question

I created an environment variable in Azure App Service. However, I'm not able to pick the value from Azure while it is published.

So I added it to the appsettings.json, and it works.

My question would be, if I add an environment variable in Azure configuration settings, shall I add it in the appsettings.json as well, or is having it in the Azure environment settings enough?

When I navigate to

https://your-web-name.scm.azurewebsites.net/Env.cshtml

I can clearly see the variable is present there. Why is this not being picked up in the code? Am I doing something wrong?

appSettings["MailKitPassword"] <-- This is not being picked up, so I have to hard-code it.

have you tried using Environment.GetEnvironmentVariable("APPSETTING_MailKitPassword") or Environment.GetEnvironmentVariable("MailKitPassword")? — Thiago Custodio, Dec 16 '19 at 20:55
I was using this var appSettings = ConfigurationManager.AppSettings; I will try using your one and come with updates — Csibi Norbert, Dec 16 '19 at 21:04
@ThiagoCustodio Environment.GetEnvironmentVariable("APPSETTING_MailKitPassword") worked! thanks. — Csibi Norbert, Dec 16 '19 at 21:08

In order to retrieve it you should use Environment.GetEnvironmentVariable("APPSETTING_MailKitPassword")

As Thiago Mentioned, you need to use GetEnvironmentVariable method to retrieve the AppSettings values,

so your code should be

Environment.GetEnvironmentVariable("APPSETTING_MailKitPassword")

However i would recommend you to store the passwords in Azure KeyVault.
