</Button>

MainViewModel.cs

using DevExpress.Mvvm;
using DevExpress.Mvvm.DataAnnotations;
// ...
    public class MainViewModel : ViewModelBase {
    // ...
        [Command]
        public void Close() {
        // ...
        }
    }
}

MainViewModel.vb

Imports DevExpress.Mvvm
Imports DevExpress.Mvvm.DataAnnotations
' ...
    Public Class MainViewModel
        Inherits ViewModelBase
' ...
        <Command>
        Public Sub Save()
' ...
        End Sub
' ...
    End Class
End Namespace

Some controls do not have a Command property. In such cases, use the CommandPropertyName property to attach the behavior to the desired command.
