Timer

Hi! I'm new to WPF. I want to add a button(initially invisible) and every minute I've to make it visible. How to do this?

Add a button set it's visibility to a property in your VM/code behind add a timer to your vm that toggles the property start the timer when you load the view

Or use the entirely XAML way and use a Storyboard.

Advanced xaml work, I have not started working with more than the basics in xaml so a storyboard did not occur to me. I can see myself going through these apps in a couple of years and shaking the head in despair.

Instead of changing the visibility you could control the button's oppacity. Something like:

DoubleAnimation animation = new DoubleAnimation(0, 1, new Duration(TimeSpan.FromMilliseconds(1400)));

yourButton.BeginAnimation(Load.OpacityProperty, animation);
