LongListSelector不存在於命名空間clr-namespace中：Microsoft.Phone.Controls; assembly = Microsoft.Phone.Controls.Toolkit

Question

我想在我的項目中使用Windows Toolkit的longlistselector，但我總是有這個錯誤。 我將命名空間添加到我的xaml中，並嘗試多次限制visual studio。 當然，該工具包與nuget包管理器一起安裝。

編輯：我在Windows Phone 8.1

這裏是XAML代碼：

誰能幫助我嗎？我不知道該怎麼辦？

LongListSelector不適用於Windows Phone 8.1，您可以使用SemanticZoom。
