In WPF-Fenster erscheint, aber Ausnahme erscheint auch

Question

Ich versuche eine neue Methode für WPF-Programm. Ich schreibe nur eine Datei, d. H. Application.xaml (Code angegeben). Ich schreibe auch Driver3.vbproj, um dieses Projekt zu kompilieren. Irgendwie ist es mir gelungen, nach wiederholten Versuchen den Fensterteil zu bekommen - aber eine Ausnahme folgt. Ich verwende die Befehlszeile zum Kompilieren (C-Pad-Stil). Die Ausnahme kann durch VS2015 Community Edition gesehen werden. Detaillierte Codetabelle unten angegeben: -

Application.xaml :-(Exception Details weiter unten)

Commandline Aufruf für Compiler :-(Das Projekt ist auf meinem Desktop)

set PATH=%PATH%;C:\Program Files (x86)\MSBuild\14.0\Bin 
msbuild "C:\Friends 

Kann mir jemand diese Ausnahme zu unterdrücken oder entfernen helfen?

Answer 1

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.
