Navigation is only supported to relative URIs that are fragments, or begin with '/', or which contain ';component/'. Parameter name: uri

突然遇到这烦恼的问题，由于心情不好，导致处理了好久。

解决办法：

1.从简单的路径检查： /page1.xaml, .../page.xaml

2.从程序集检查：

var nameHelper = new AssemblyName(Assembly.GetExecutingAssembly().FullName);

            var version = nameHelper.Version;

            var full = nameHelper.FullName;

            var name = nameHelper.Name;

3.从URLmap检查：

      <navigation:UriMapper x:Key="UriMapper">

            <navigation:UriMapper.UriMappings>

                <navigation:UriMapping Uri="" MappedUri="/MainPage.xaml"/>

                <navigation:UriMapping Uri="/{pageName}" MappedUri="/Views/{pageName}.xaml"/>

                <navigation:UriMapping Uri="/{pageName}/{key}" 

                                   MappedUri="/Views/{pageName}.xaml?entityGuid={key}"/>

            </navigation:UriMapper.UriMappings>

        </navigation:UriMapper>

        

真正解决：

在异常退出发现：

   private void RootFrame_NavigationFailed(object sender, NavigationFailedEventArgs e)
        {
            if (System.Diagnostics.Debugger.IsAttached)
            {
                // A navigation has failed; break into the debugger
                System.Diagnostics.Debugger.Break();
            }
        }

其中的naveigationFailedEventArgs e的e显示 no xaml in view/setting.

说明我设置了Url map，但没有写好导航的格式。

至此问题解决。
