我正在尝试在UWP应用中使用LiveCharts库。我通过NuGet安装了LiveCharts和LiveCharts.Uwp。我按照LiveCharts网站上提供的步骤重新创建了他们的第一个示例,但我总是在XAML文件中收到以下错误:
名称" CartesianChart"命名空间中不存在"使用:LiveCharts.Uwp"
该物业'系列'没有在类型' CartesianChart'
(见附图)。
以下是我的MainPage.xaml和MainPage.xaml.cs的代码:
MainPage.xaml中:

我无法重现此问题。我使用Visual Studio 2017并使用此命令行:“PM&gt; Install-Package LiveCharts.Uwp”。看起来您还没有成功添加引用LiveCharts.UWP。尝试清除Nuget缓存并再次安装该程序包。 Here是关于如何清除缓存的参考。
