c# - VisualStudio does not find namespace

Question

Well, I'd like to use a class of a namespace in my Mainwindow.xaml

Image

As you see the namespace called WPF.Tools

Now I create a local at the top to the XAML

xmlns:webutil="WPF.Tools"

And in the Grid I have a WebBrowser where I'd like to use a a method of the class of the namespace:

<WebBrowser webutil:WebBrowserBehaviors.BindableSource="{Binding SelectedRSSFeed.Link}"  Grid.Column="1" Margin="10,10,10,10" Grid.RowSpan="3" Grid.Row="0"/>

If I hover over it it says: The name "WebBrowserBehaviors" does not exist in the namespace "WPF.Tools".

I also added a Project Reference so I don't think this is the Problem

Answer 1

Your reference seems wrong.

It should be:

xmlns:webutil="clr-namespace:WPF.Tools;assembly=WPF.Tools
