命名空间“System.Windows”中不存在类型或命名空间名称“部署”

Question

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

错误 27 命名空间“System.Windows”中不存在类型或命名空间名称“Deployment”（您是否缺少程序集引用？） C:\Users\sahluwai\Desktop\cusControls2\leitch\HarrisSilverlightToolkit\Toolkit\ Source\Controls\Input\IpAddressControl\CcsIPAddressControl.cs 854 36 输入

我已确保文件顶部有“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）：

private bool ValidateIpOctet(TextBox IpOctet, int OctetIndex)
    {
        bool redraw = false;

        if (OctetIndex < 0 || OctetIndex >= this.m_IpAddress.IpOctets.Length)
            return redraw;

        int i = OctetIndex;

        this.m_IpAddress.IpOctets[i] = String.IsNullOrEmpty(IpOctet.Text) ? "0" : IpOctet.Text;

        uint iOctet = uint.Parse(this.m_IpAddress.IpOctets[i]);
        if (i == 0)

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。
