XamlparseException me vuelvo loco!

Question

¡Esta XamlParseException me está volviendo loco! Estoy usando .NET 3.5 en Visual Studio 1020 Este es mi XAML:

<Window x:Class="WinformsHost.MainWindow"

        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="Advanced Notepad" Height="350" Width="525" Loaded="Window_Loaded">
<DockPanel>
    <Menu DockPanel.Dock="Top">

        <MenuItem Header="File">

        </MenuItem>

        <MenuItem Header="Format">
            <MenuItem Header="Word Wrap" IsCheckable="True" />
            <MenuItem Header="Font..." />
        </MenuItem>

        <MenuItem Header="View">

        </MenuItem>

        <MenuItem Header="Language">

            <RadioButton x:Name="rbtPython" Content="Python" />
            <Separator />
            <RadioButton x:Name="rbtText" IsChecked="True" Content="Text" />
        </MenuItem>

        <MenuItem Header="Help">
            <MenuItem Header="View Help" />
            <Separator />
            <MenuItem Header="About Notepad" />
        </MenuItem>

    </Menu>
    <StatusBar x:Name="stbStatus" DockPanel.Dock="Bottom" Visibility="Collapsed">
        <TextBlock x:Name="txtStatus" Text="Status" />
    </StatusBar>
</DockPanel>
</Window>

Entonces, de nuevo, ¿podría ser mi código? Aquí está la excepción:

Answer 1

No creo que esto sea realmente una XamlParseException: creo que es una TargetInvocationException que se ha envuelto en una XamlParseException. Eche un vistazo a la mejor excepción interna:

Nlog.config.nlogConfigurationException Mensaje = Excepción ocurrida al cargar la configuración de 'C: Users Mohit Documents Visual Studio 2010 Projects Notepad Notepad bin debug nlog.config'

Parece que tiene un archivo de configuración Borked, posiblemente debido a un XML inválido o posiblemente por alguna razón más específica.

Cuando obtienes una misteriosa XamlParseException, es siempre Vale la pena comprobar la innerexception para obtener un TargetinVocationException (y perforar desde allí si hay una). Sí, ¡es muy confuso y engañoso!

Answer 2

Sé que esta es una vieja pregunta, pero espero que esto ayude a alguien.

Tenía una propiedad de la ventana principal que era un objeto comercial ... así que cuando la ventana se inicializó, el objeto comercial intentó inicializar ... genial, pero la capa de acceso de datos no se había configurado, por lo tanto, arrojó un error ... .

Entonces, C# llamó a eso un error de análisis XML porque sucedió muy temprano ... realmente fue arrojado en código.

Answer 3

Resolvió el mismo problema al incluir los archivos DLL y config de referenciados en la misma carpeta que el archivo EXE. Intentar ejecutar el exe solo causará una excepción de nivel de Windows.
