Hello!

What can i replace WPF code

Style style = Application.Current.FindResource("key") as Style;

in Noesis / Unity ?

in code behind working:

Style style = (Style)this.FindResource("key");

but I need to find the Style in Theme.XAML from converter for my ViewModel

I will be glad to answer

I'm write this code:

using Noesis;
internal static class Utilities

 static FrameworkElement frameworkElement = new FrameworkElement();
 
 internal static Style GetStyle(string key)
        {
            return  (Style)frameworkElement.FindResource(key);
        }
}

using

Utilities.GetStyle("key");

And this working
This allows you to apply the style from Global XAML Theme in viewmodel, converter and etc

Why Noesis allows you to find a style not related to the new FrameworkElement - I don't know, but it works

if someone explains the mechanism, I'll be happy

Accessing the Application.Resources is something that we should expose, I created a ticket in our bugtracker for this feature: https://www.noesisengine.com/bugs/view.php?id=1505

This is working because the default behavior of FindResource in any FrameworkElement is:

First search for the resource in same element Resources
Next search in the same element Style.Resources
Next search in the same element Template.Resources
Repeat the process in the logical tree upwards until the root is reached
Finally search in the Application.Resources
