How do add and read appsettings in Visual Code?

Chaumette Garcia 0

I'm using Visual Code and I want set values in the appsettings file. Then retrieve them using Configuration Manager - see below - I'm getting following error:

Unhandled exception. System.NullReferenceException: Object reference not set to an instance of an object. at Program.Main() in C:\Chaumette\Development\IntuneTokenApp\Program.cs:line 11

Visual Code is new to me- I'm not sure why it's not finding the value. I manually added appSettings.config - Is there any special configuration needed?

var applicationId = ConfigurationManager.AppSettings["appId"].ToString();

Appsetting.config:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6.1" />
    </startup>
    <appSettings>
      <add key="appId" value="App ID created from 'Create a Web App' procedure"/>
      <add key="appKey" value="Key created from 'Create a key' procedure" />
      <add key="tenantDomain" value="contoso.onmicrosoft.com"/>
    </appSettings>
</configuration>
