From a Tip/Trick here on CP

protected virtual bool SetProperty
(ref T storage, T value, [CallerMemberName] string propertyName = null)
{
if (Equals(storage, value)) return false;

    storage = value;
    this.RaisePropertyChanged(propertyName);
    
    return true;
}

protected virtual bool SetPropertySafely
(ref T storage, T value, \[CallerMemberName\] string propertyName = null)
{
    if (Equals(storage, value)) return false;
    
    storage = value;
    this.RaisePropertyChangedSafely(propertyName);
    
    return true;
}

protected virtual bool SetPropertySafelyFast
(ref T storage, T value, \[CallerMemberName\] string propertyName = null)
{
    if (Equals(storage, value)) return false;
    
    storage = value;
    this.RaisePropertyChangedSafelyFast(propertyName);
    
    return true;
}

The topic is about making data changes visible ASAP on the UI (WPF) from another thread. Either all methods above are safe & fast, or all of them are slow and unsave. I tend towards the latter. :laugh:
