Instantiation of POCO objects with ServiceStack's IAppSettings is not working - servicestack

Question

I have registered AppSettings within my AppHost as shown below:
container.Register<IAppSettings>(new AppSettings());
I have added following settings within my web.config file:
<appSettings>
<add key="baseaddress" value="http://example.com" />
<add key="credential" value="{Username:foo,Password:bar}" />
</appSettings>
That's my service:
public class ExampleService : Service
{
public IAppSettings Settings { get; set; }
public void Post(ExampleRequest request)
{
// NOT WORKING -> always NULL!
var credentials = Settings.Get<Credential>("credential", null);
// OK
var baseUrl = Settings.GetString("baseaddress");
// more code...
}
}
This is my Credential class:
public class Credential
{
public string Username { get; set; }
public string Password { get; set; }
}
The baseUrl is always set but the credentials variable is always NULL and I don't know why...

Answer 1

In the latest v4.0.31 of ServiceStack there's First Class support for AppSettings so you don't have to register it yourself as it's already registered for you:
container.Register<IAppSettings>(new AppSettings());
But I've tested this and it works as expected where it deserializes into a populated Credential instance with:
var credential = AppSettings.Get<Credential>("credential", null);
Are you sure you're using the exact key names? as your last sentence uses baseUrl and credentials but your appSettings says baseaddress and credential.

You would need something like this in your config <security mode="TransportWithMessageCredential"> to automatically add a security header to your post. Or you need to add and parse your own headers. You don't show your full web config or a sample call to your "Post" so I am running on some assumptions here.
