C# xaml telerik赢得'；无法解析RadGridView

Visual Studio中的Intellisense由于某种原因无法接收telerik RadGridView

我的项目以.NET 3.5为目标，有以下参考资料：

Telerik.Windows.Controls

Telerik.Windows.Controls.GridView

Telerik.Windows.Controls.Input

Telerik.Windows.Data

所有这些都适用于.NET3.5，运行时版本为2.0.X

我的代码：

<Window x:Class="Project.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
    Title="MainWindow" Height="350" Width="525">

<Grid Loaded="Grid_Loaded">
    <StackPanel>
        <telerik:RadGridView></telerik:RadGridView> <-- this won't resolve
