[C# WPF] Failed to resolve resource. What is the problem, how to solve it?

Question

.NET

Good day!
I'm working on an application that contains a DataGrid table . In
addition to this, filters are required. I tried to install https://www.codeproject.com/Articles/42227/Automat...
On completion

<DataGrid ColumnHeaderStyle="{StaticResource {ComponentResourceKey 
           TypeInTargetAssembly={x:Type filter:DataGridHeaderFilterControl}, 
           ResourceId=DataGridHeaderFilterControlStyle}}"/>

Gives an error
"Failed to resolve the resource"
Tried to additionally connect the resource separately

<Window.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="pack://application:,,,/DataGridFilterLibrary;component/Themes/Generic.xaml" />
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Window.Resources>

The error has not disappeared~
How can I solve the problem? Or maybe there is something simpler for filters (like Excel autofilters)?..
