Visual Studio 2015 RTM 1更新错误交互＆＃39;存在于＆＃39; Microsoft.Xaml.Interactivity中

Question

将visual studio 2015更新为Update 1后，我在尝试构建时遇到此错误..

Error CS0433 The type 'Interaction' exists in both
'Microsoft.Xaml.Interactivity, Version=1.0.2.0, Culture=neutral,
PublicKeyToken=31bf3856ad364e35' and 'Microsoft.Xaml.Interactivity,
Version=12.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' 

同样的事情：

• BehaviorCollection
• EventTriggerBehavior
• ActionCollection
• InvokeCommandAction

该应用程序在另一台在Visual Studio 2015上没有更新1的笔记本电脑上运行良好...
