MVVM WPF - Login Logic
<p>I need help regarding the authentication property in the app.</p>

<p><a href="https://i.stack.imgur.com/ztZPz.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ztZPz.png" alt="enter image description here"></a></p>

<p>Q1: I deserialize the JSON the some models, so in the ViewModel I have a model that has the idUser (response from the server). How can I use that information in the FriendsViewModel without breaking the MVVM architecture?</p>

<p>Best regards,
Antoine</p>
