关于c#：命名空间”System.Windows”中不存在类型或命名空间名称”Deployment”

The type or namespace name ‘Deployment’ does not exist in the namespace ‘System.Windows’

我目前正在尝试通过将文件链接到 wpf 库将我的 silverlight 项目更改为 wpf，以便以后我可以使用这两个应用程序。我从 silverlight 项目链接到我的 wpf 项目的这个文件给了我这个错误：

Error 27 The type or namespace name ‘Deployment’ does not exist in the namespace ‘System.Windows’ (are you missing an assembly reference?) C:\\Users\\sahluwai\\Desktop\\cusControls2\\leitch\\HarrisSilverlightToolkit\\Toolkit\\Source\\Controls\\Input\\IpAddressControl\\CcsIPAddressControl.cs 854 36 Input

我已确定文件顶部有”使用 System.Windows”。

这是函数的样子，有错误(请查看注释以查看示例错误位置)：

不要使用来自 System.Windows.Deployment 的调度程序 – 这是 Silverlight 特有的。如果您的意图是调用属于 GUI 的 Dispatcher 上的某些内容，请改用 System.Windows.Application.Current.Dispatcher。
