Problem in finding styles

[eykaraduman]

Hi,
I create a new avalonia project with jetbrains rider and add the styles below to App.xaml. (target framework is net 6.0)

<Application xmlns="https://github.com/avaloniaui"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:local="using:Avalonia.NETCoreMVVMApp1"
             x:Class="Avalonia.NETCoreMVVMApp1.App">
    <Application.DataTemplates>
        <local:ViewLocator/>
    </Application.DataTemplates>

    <!-- <Application.Styles> -->
    <!--     <FluentTheme Mode="Light"/> -->
    <!-- </Application.Styles> -->
    <Application.Styles>
        <StyleInclude Source="avares://Avalonia.Themes.Fluent/Accents/BaseLight.xaml"/>
        <StyleInclude Source="avares://Aura.UI.FluentTheme/AuraUI.xaml"/>
        <StyleInclude Source="avares://Avalonia.Themes.Default/Accents/BaseLight.xaml"/>
        <StyleInclude Source="avares://Avalonia.Themes.Default/DefaultTheme.xaml"/>
    </Application.Styles> 
</Application>

I get an exception in row <StyleInclude Source="avares://Aura.UI.FluentTheme/AuraUI.xaml"/>.

How can i solve this problem?

Any update on this?
I've got the same issue, but for some reason it only happens on some systems 🤔
