wpf - 无法从程序集 PresentationFramework 加载类型 'System.Windows.Controls.Primitives.MultiSelector'

Question

我正在尝试使用 WPFToolkit 中的网格，但出现错误:

DisplayDataMapping.xaml (9,89):
    errorMC1000: Unknown build error, 
    'Could not load type 'System.Windows.Controls.Primitives.MultiSelector' from assembly 
    'PresentationFramework, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. Line 9 Position 89.' 

这是xaml:
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:toolkit="http://schemas.microsoft.com/wpf/2008/toolkit">

WPF Toolkit 依赖于 .NET Framework 3.5 SP1(以防万一您还不知道)。
