Question

我正在为wpf程序尝试一种新方法。我只写一个文件，即Application.xaml（代码给定）。我还编写Driver3.vbproj来编译这个项目。不知怎的，我成功地获得了窗口部分经过多次尝试 - 但接下来是一个例外。我使用命令行进行编译（C-Pad样式）。通过VS2015社区版可以看到例外情况。下面给出了详细的代码集： -

Application.xaml :-(下面给出的例外情况）

from test_rest_create_method.serializers import TempleSerializer
>>> serializer_temple = TempleSerializer()
>>> print(repr(serializer_temple))
TempleSerializer():
    history = CharField(style={'base_template': 'textarea.html'})
    timings = TimingsCreateUpdateSerializer(many=True):
        id = IntegerField(label='ID', read_only=True)
        Timings_to = TimeField(format='%I:%M%p')
        Timings_from = TimeField(format='%I:%M%p')

未处理的类型＆＃39; System.Windows.Markup.XamlParseException＆＃39;       发生在PresentationFramework.dll中       附加信息：＆＃39;在类型上调用构造函数       ＆＃39; System.Windows.Application＆＃39;匹配       指定的绑定约束引发了异常。＆＃39;
      行号＆＃39; 1＆＃39;和行位置＆＃39; 14＆＃39;。

Driver3.vbproj

有人可以帮助我压制或删除该异常吗？

Dear Friends,
     I am very happily announcing that I solved my own problem.The solution was very simple indeed.
SOLUTION:
Remove the line-->    StartupUri="Application.xaml"
The window appears and is stable.Just for clarity I am repeating the Application.xaml file code:-

<Application x:Class="Application"
  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">

<x:Code>
         <![CDATA[

Public Sub New()
Dim won As Object = New Window()
              won.Height="300" 
              won.Width="900" 
              won.Title="Guddlu_3" 
              won.Background=New SolidColorBrush(Colors.LightSteelBlue) 
won.Show()              
End Sub 

         ]]>
</x:Code>

</Application>

Driver3.vbproj is the same

Thanks a lot and regards to all.
