I am having some problems for getting the configuration values using this method in my web application in .net core. 

```
 var settings =  ConfigurationManager.GetSection("JwtBearerSettings/Issuer");

```

This method is called by one project I am referencing. It is also in .NET Core 2.2 and the config settings are on the file

> 
> appsettings.json
> 
> 
> 

The thing is that when I am debugging always I get `settings == null` I have been looking for similar questions but I couldn't solve this. 

My json is

```
{
     "JwtBearerSettings": {
        "Issuer": "Auth.MyStuff.Api",
        "PrivateKey": "Blablabla",
        "ExpirationTime": "15"
        }
}

```

Do you know if is even possible to use this method?

Am I missing something between, for getting the web app configuration with my library?
