In wpf window appears but exception also appears

I am trying a new method for wpf program. I write only one file i.e. Application.xaml (Code given). I also write Driver3.vbproj to compile this project. Somehow I succeeded in getting the window part after repeated attempts - but an exception follows. I use command line for compiling (C-Pad style). The exception can be seen through VS2015 community edition. Detailed codesets given below:-

Application.xaml:-(Exception details given below)

<Application x:Class="Application"
  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
  StartupUri="C:\Users\VEKATRAMAN\Desktop\Dll_Output_Testing_Proj\Application.xaml">
<x:Code>

         <![CDATA[

Public Sub New1()
           InitializeComponent()
Try     

Dim won As Object = New Window()
              won.Height="300" 
              won.Width="900" 
              won.Title="Guddlu_3" 
              won.Background=New SolidColorBrush(Colors.LightSteelBlue) 
won.Show()
Catch ex As Exception
        MsgBox("Something wrong somewhere!!??!!")
End Try

End Sub   

         ]]>
</x:Code>

</Application>

Commandline call for compiler:-(The project is on my desktop)

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

Can somebody help me out to suppress or remove that exception?

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.
