c# - System.Windows.Markup.XamlParseException' occurred in PresentationFramework.dll?

Question

I'm using WPF on C# as code bellow

<Window       
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d"
    xmlns:utility="clr-namespace:DVRClientInterface.Utility"
    xmlns:toolkit="http://schemas.xceed.com/wpf/xaml/toolkit"     
    xmlns:wpftoolkit="clr-namespace:Microsoft.Windows.Controls;assembly=WPFToolkit"   
    xmlns:customControl="clr-namespace:DVRClientInterface.CustomControls"    
    x:Class="DVRClientInterface.MainWindow"
    WindowStyle="None" ResizeMode="CanMinimize"
    AllowsTransparency="True"
    WindowState = "Maximized"
    WindowStartupLocation="CenterScreen"    
    StateChanged="Window_StateChanged" 
    KeyUp="Window_KeyUp" 
    KeyDown="Window_KeyDown"    
    Closing="Window_Closing" Loaded="Window_Loaded"
     >
    <!-- WindowState = "Maximized" -->
    <Window.Background>
        <ImageBrush ImageSource="Resourcesmain_background.png"/>
    </Window.Background>

    <Grid x:Name="MainWindowGrid">
     //My GUI Code here

    </Grid>
</Window>

When I run the app, it will throw following exception

An unhandled exception of type 'System.Windows.Markup.XamlParseException' occurred in PresentationFramework.dll

Additional information: 'The invocation of the constructor on type 'DVRClientInterface.MainWindow' that matches the specified binding constraints threw an exception.' Line number '9' and line position '5'.

If there is a handler for this exception, the program may be safely continued.

Line 9 is xmlns:customControl="clr-namespace:DVRClientInterface.CustomControls".

But I don't know why, before that the XAML still work fine. I just edit the code in the C++ project, and after that it always throw that exception.

Many topics said that it was caused by the projects config, but I don't know where in my projects config raise this exception.

Someone can suggest me how to fix it?

Answer 1

This is not a problem with XAML. The error message is saying that it tried to create an instance of DVRClientInterface.MainWindow and your constructor threw an exception.

You will need to look at the "Inner Exception" property to determine the underlying cause. It could be quite literally anything, but should provide direction.

An example would be that if you are connecting to a database in the constructor for your window, and for some reason that database is unavailable, the inner exception may be a TimeoutException or a SqlException or any other exception thrown by your database code.

If you are throwing exceptions in static constructors, the exception could be generated from any class referenced by the MainWindow. Class initializers are also run, if any MainWindow fields are calling a method which may throw.
