我目前在构建我的Xamarin.Forms解决方案时遇到了问题.我收到了错误The "XamlCTask" task failed unexpectedly.我试着查看Xamarin日志和Stacktrace,但我似乎无法找到问题所在.我可以开始寻找任何建议吗？

堆栈跟踪

严重级代码说明项目文件行抑制状态错误"XamlCTask"任务意外失败.System.ArgumentException:已添加具有相同键的项.

我遇到的小问题.我一直试图找到错误,但我找不到它,如果你可以指出它,或者给我一些很好的修正.至于这里的代码是:

using UIKit;

namespace App10
{
public class Application
{
    // This is the main entry point of the application.
    static void Main(string[] args)
    {
        var listView = new ListView();
        listView.ItemsSource = new string[] {
        "Trainer 1",
        "Trainer 2",
        "Trainer 3",
        "Trainer 4",
        "Trainer 5",
        "Trainer 6",
        };  

    listView.ItemsSource.Add("Trainer");
