I have just been learning about how styles and control templates in WPF can affect the appearance of buttons,
I'm trying to set the Button's FlatStyle, in the resources I've seen I can't find anything that tells me how I can do this, in Windows Forms this is set through FlatStyle = Flat.
How would one do this in WPF?
The ToolBar class defines a Style that makes Buttons look flat. An example of using it is:
<Button Style="{StaticResource {x:Static ToolBar.ButtonStyleKey}}"/>
This also works for a ToggleButton when using ToggleButtonStyleKey.
WPF lets you completely restyle controls to make them look like whatever you want, which is why it doesn't have such a specific FlatStyle property on the Button control.
