Description Karol S 2016-08-25 06:52:38 UTC
When I use MergedWith in App.xaml, imported values are only available in this (App.xaml) file, but they aren't propagated to all ContentPages. This means I have to apply MergedWith to ResoruceDictionaries on all pages.

For example:

<?xml version="1.0" encoding="utf-8" ?>
<Application xmlns="http://xamarin.com/schemas/2014/forms"
    <ResourceDictionary MergedWith="shared:SharedDictionary">
            <Style x:Key="BaseLabel" TargetType="Label">
                <Setter Property="TextColor" Value="{StaticResource SharedColor}" /> <!-- SharedColor is visible only in this file -->

Could you provide a small reproduction project which demonstrates this issue? Without knowing how you're using "SharedDictionary" elsewhere in the project, we don't know how to reproduce the problem you're seeing.

I'm quite sure this was fixed in the past months, and wasn't able to reproduce in 2.3.4-pre1.
I've added a unittest to make sure it doesn't regress: https://github.com/xamarin/Xamarin.Forms/commit/6670ca58458582a1a670f97d17958220802f84b0

Please reopen and provide a valid reproduction project if it's not fixed for you in 2.3.4-pre1
