Question

The goal is to display the information that the application is working. So I’m looking for an intelligent implementation sample of a loading spinner using WPF / MVVM.

Answer 1

I wrote this user control which may help, it will display messages with a progress bar spinning to show it is currently loading something.

  <ctr:LoadingPanel x:Name="loadingPanel"
                    IsLoading="{Binding PanelLoading}"
                    Message="{Binding PanelMainMessage}"
                    SubMessage="{Binding PanelSubMessage}" 
                    ClosePanelCommand="{Binding PanelCloseCommand}" />

It has a couple of basic properties that you can bind to.
