I want to pass the current DataContext (which is an instance of a ViewModel) as a CommandParameter on a WPF Button. What would be the syntax I should use?

<Button 
  x:Name="btnMain"
  Command="infra:ApplicationCommands.MyCommand"
  CommandParameter="{Binding ???}"
 />

An empty Binding, without a path, binds directly to the DataContext, so

{Binding}

is enough to make it work! Your example:

<Button 
  x:Name="btnMain"
  Command="infra:ApplicationCommands.MyCommand"
  CommandParameter="{Binding}"
 />
