WPF Design error ( VerticalScrollBarVisibility) and ( HorizontalScrollBarVisibilty ) does not exist in the icsharpcode.net/sharpdevelop/avalonedit

Question

I have found a source code with a very nice WPF UI that I want to take a look at but when I try to look at one of the main UIs in the project it gives me 2 errors about icsharpcode.net/sharpdevelop/avalonedit

What I have tried: I tried downloading ICSharpCode.AvalonEdit.dll and adding it as a reference but I found out that it already was there so it didn't help with anything.

The code that gives me the(click here for image) errors: x:Class="ViiPer.ViiPerUI" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:local="clr-namespace:ViiPer" xmlns:avalonedit="http://icsharpcode.net/sharpdevelop/avalonedit"

It seems the link used to return an XML schema but now redirects to the organization's github page. You can try contacting them directly.

The documentation hasn't been updated since 2014, so I guess they haven't moved it to a new address.

At the end of the day, it's just a link to the XAML files, so you can probably compile them yourself https://github.com/icsharpcode/AvalonEdit/search?l=XML. Do check the licensing of the project, though.
