How can i modify the Theme Basic? Like the primary color of Buttons or styles in general?

I try with this that i found in the Developer guide but show me a error!

```auto
<Fuse.BasicTheme>
    <Button FontSize="20"/>
</Fuse.BasicTheme>

Or

<Fuse.BasicTheme.BasicTheme ColorScheme="Amber">

Thanks!

```

The first example shuld be

```auto
<Fuse.BasicTheme.BasicTheme>

```

The second one should work, so I’m not sure what’s wrong there. Can you please tell us what error message you are getting?
