WPF create your own type

I want to create a template (resource dictionary) for my app. where my type inherits the button type and I then can call it through:

<my-custom-type inherit from button>
</my-custom-type inherit from button>

And of course in WPF.

More specifically, I would like to create copies of the control in the image below with simple XAML syntax as above.

button

There are two approaches to this, each with their own pros and cons:

Templates allow you to reuse a section of XAML. There is (almost always) no code-behind, and you certainly won't be deriving from Button. For example, if you wanted to have a bordered text box repeated in an ItemsControl:

<DataTemplate x:Key="MyDataTemplate">
    <Border>
        <TextBox/>
    </Border>
</DataTemplate>

Or in a button class you use ContentTemplate:

<Button ContentTemplate={StaticResource MyTemplate}>
</Button>

And you would use it as XTemplate="{StaticResource MyDataTemplate}" in an existing control that used templates. This is usually the way to go. Note that the name of the property won't be Template, but ItemTemplate, or ContentTemplate or something similar.

The exception is if you want custom behavior, in which case you use a UserControl. This technically could inherit from Button though you usually wouldn't. Subclassing a basic control should only be done if you are sure you actually want to do that. Once your user control is created, the syntax would look similar to what you have in your question:

<local:MyButton>
</local:MyButton>

Note that "local" is a made-up xmlns. Your user control would consist of whatever controls you wanted, and you can expose "attributes" to the using code via dependency properties.
