UWP - Reference StaticResource from different style resource dictionary: Failed to assign to property 'Windows.UI.Xaml.ResourceDictionary.Source'

Hello my team and I recently started developing an win10 uwp application. Application will have a lot of views and components so heavy use of styles is expected, so we need to organize our styles through file/folder structure we did this using following structure (unfortunately I cannot embed images yet see the link):
Anyways my Resource.xaml merges all other dictionaries as following:
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="/Resources/Colors.xaml" />
<ResourceDictionary Source="/Resources/Icons.xaml" />
<ResourceDictionary Source="/Resources/Fonts.xaml" />
<ResourceDictionary Source="/Resources/Converters.xaml" />
<ResourceDictionary Source="/Resources/Buttons.xaml" />
<ResourceDictionary Source="/Resources/RadioButton.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
And in my App.xaml I reference this dictionary:
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Resources/Resources.xaml" />
</ResourceDictionary.MergedDictionaries>
<vm:ViewModelLocator x:Key="Locator" d:IsDataSource="True" />
</ResourceDictionary>
</Application.Resources>
Now I managed to find the source of the problem in my RadioButton.xaml I reference a brush defined in Colors.xaml using StaticResource lookup:
<Setter Property="Foreground" Value="{StaticResource TopMenuTextBrush}" />
If I remove this line everything will start but with it I get following exception:
Exception {Windows.UI.Xaml.Markup.XamlParseException: The text associated with this error code could not be found.
Failed to assign to property
'Windows.UI.Xaml.ResourceDictionary.Source' because the type
'Windows.Foundation.String' cannot be assigned to the type
'Windows.Foundation.Uri'. [Line: 28 Position: 37]} System.Exception
{Windows.UI.Xaml.Markup.XamlParseException}
Interesting thing is when I start the app with this line commented and uncomment it visual studio will recognize the brush and apply it correctly, it only breaks on application start.
We used same approach before when developing WPF, so I'm thinking it might have to do with something regarding application deployment.
All help is greatly appreciated.

Exception = {Windows.UI.Xaml.Markup.XamlParseException: The text associated with this error code could not be found.
The problem is that you have used wrong ResourceDictionary source . I found the Resources.xaml and other xaml file stored in the same level directory in your screenshot. So you could not declare the parent directory of these xaml files within source. Please modify ResourceDictionary like the following
<ResourceDictionary Source="Colors.xaml"/>
For more you could refer to ResourceDictionary and XAML resource references.

WPF Cannot locate resource

I have a resource file and two views. This views use a resource file
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="/Dictionary1.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
And it will work while i dont put one view to the another. In this case i get this error
Cannot locate resource 'dictionary1.xaml'
How to fix it?

Use Pack Uri's
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="pack://application:,,,/Assembly_Name;component/Dictionary1.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>

If Dictionary1.xaml in your project's rootpath, remove '/' before Dictionary1
<ResourceDictionary Source="Dictionary1.xaml"/>
Or you can use packuri like :
/yourAssemblyName;component/Dictionary1.xaml

Use an External ResourceDictionary in a WindowsPhone 7/8 app

I have separated libraries for my applications and I want to put ResourceDictionary to keep my default styles in one place.
In my project mylib that is build to mylib.dll i have Styles/General.xaml:
<ResourceDictionary
x:Class="gjdapi.Style.General"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:System="clr-namespace:System;assembly=mscorlib">
I'm referencing it in my App.xaml:
<Application.Resources>
<ResourceDictionary x:Key="General">
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="/mylib;component/Styles/General.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
Build for Styles/General.xaml is set to Page.
I found some tips here:

xClassNotDerivedFromElement error when adding Code Behind to Resource Dictionary in silverlight
Error using ResourceDictionary in Silverlight
but nothing seems to work i always hit this exception:
Message "Parser internal error: Object writer 'xClassNotDerivedFromElement'. [Line: 15 Position: 32]" string
Please tell me what am I missing?

As lisp suggested ResourceDictionary can't have code behind so line x:Class="gjdapi.Style.General" should be removed

Shared library not seeing resource dictionary

I have two wpf solutions that use the same class library (one I have written). The library references sytles (as static resources) that are in a resource dictionary of the main project. In one of those solutions, the library finds these static resources in the resource dictionary but in the other project the static resources are not resolved. In both cases the Resource dictionary is declared in the App.Xaml of the main application as follows:
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary>
<local:AppBootstrapper x:Key="bootstrapper" />
</ResourceDictionary>
<ResourceDictionary Source="StoryMakerStyle.xaml" />
<ResourceDictionary Source="Resources\GlassButton.xaml"/>
<ResourceDictionary Source="Resources\Slider.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
Where StoryMakerStyle.xaml is the name of the resource dictionary in one app. It is called FlashcardsStyle.xaml in the other. The other 2 ResourceDictionary references are the same in both solutions.
Any suggestions as to why references to the resource dictionary are resolved in one solution but not the other?
Thanks in advance

I'm assuming that this is a solution of 2 project. You need to specify which project when referencing the ResourceDictionaries like so:
<ResourceDictionary Source="/ProjectNamespace;Resources/GlassButton.xaml"/>
<ResourceDictionary Source="/ProjectNamespace;Resources\Slider.xaml" />

In WPF how do I reference a static resource that is defined in a different XAML file?

In WPF how do I reference a static resource that is defined in a different XAML file? It's in the same project.

The other XAML file will need to be a resource dictionary. You merge it into the current file using the MergedDictionaries property of the current ResourceDictionary. See Merged Resource Dictionaries on MSDN. Their example:
<Page.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="myresourcedictionary.xaml"/>
<ResourceDictionary Source="myresourcedictionary2.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Page.Resources>
Then within that Page object you can reference static resources defined in myresourcedictionary.xaml or in myresourcedictionary2.xaml.

"different XAML file" could mean a few different things:
App.xaml: Resources are automatically included in the resource tree of anything that's opened so you don't need to do anything extra.
Window or Page .xaml: Resources can be accessed by any child of an instance of the object like a UserControl that is used in a Window.
ResourceDictionary: Needs to be explicitly merged into the resource tree somewhere above where it is used. This can be App.xaml, Windowxx.xaml, or some lower level element. Use ResourceDictionary.MergedDictionaries to do this.
There are also lots of alternate ways to specify the path but this is the simplest:
<Window>
<Window.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Resources/MyResourceDict.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Window.Resources>
