as soon as the initialization statement starts and hitting Resource dictionary in the xaml it threw the above mentioned exception.

but if i tried the same for a wpf application and not a library it works like charm. any clues?

Question

I am getting the following exception while I am assigning value to «Source» property in ResourceDictionary as MyButton.xaml file (which inherits Button class).

«ResourceDictionary LoadFrom operation failed with URI ‘MyButton.xaml’.» as innerException.

I implemented following code.

Note: I am using Visual Studio 2012 (update 4 is installed).

Note: App.xaml and MyButton.xaml are in same directory.

Thanks in advance.

>>Can’t we use .xaml file as resourceDictionary ?

Yes, we can, but the important thing is that ResourceDictionary can only support Brush, Style, Template etc.

For your requirement, creating a UserControl will be a good choice:

Following is the implementation for MyButton.xaml

That will be the problem. WPF is expecting MyButton.xaml to be a resource dictionary not a xaml definition of a button. There is a good blog post here on what resources are.

To create a resource dictionary just right click and select add new item the select. Resource Dictionary. You can then either add the button definition (making sure to use x:shared=»false») or preferably define a style for the button.

Can’t we use .xaml file as resourceDictionary ?

It will become difficult to convert my code from MyButton.xaml file to ResourceDictionary, because

1. I need code-behind file for implementing event handlers, properties and methods.

2. For a ResourceDictionary, we cannot get designer interface like in xaml file.

This designer is needed because, later I need to develop templates consisting several controls. And it will become quite difficult to manage and align controls by the code.

Question

My colleague has been working on a new WPF app. It’s written using VS 2015, .NET 4.5.2. When we run it from within VS it runs fine. We’re using ClickOnce deployment via TFS Build/Release. After installing the same app via ClickOnce, it doesn’t run at all. In fact, it never even pops up before crashing. It just instantly crashes. The only thing you can see is this in the Event Viewer:

Exception Info: System.Windows.Markup.XamlParseException
at System.Windows.Markup.WpfXamlLoader.Load(System.Xaml.XamlReader, System.Xaml.IXamlObjectWriterFactory, Boolean, System.Object, System.Xaml.XamlObjectWriterSettings, System.Uri)
at System.Windows.Markup.WpfXamlLoader.LoadBaml(System.Xaml.XamlReader, Boolean, System.Object, System.Xaml.Permissions.XamlAccessLevel, System.Uri)
at System.Windows.Markup.XamlReader.LoadBaml(System.IO.Stream, System.Windows.Markup.ParserContext, System.Object, Boolean)
at System.Windows.Application.LoadComponent(System.Object, System.Uri)
at CoreFramework.App.InitializeComponent()
at CoreFramework.App.Main()

I tried putting in a MessageBox.Show in the application’s constructor, after the InitializeComponent call. Even that did not show.

How is this possible? What’s going on? How do we determine what’s run when we can’t even begin to find out where its wrong?

At the entry point when app.xaml is merging resource dictionaries or your mainwindow are loading, a resource dictionary isn’t where it’s expected to be or cannot be read for some reason.

I’ll just merge this resource dictionary. dead.

Hope that helps.

Given what you’ve said, I’ve taken a look at the App.xaml. There are 3 resource dictionaries that my colleague is merging into a single resource dictionary. One is one that we’ve written and it is where it should be. The other 2 are related to a third party library (ModernUI). Here is the contents of our App.xaml:

How do I determine if that FirstFloor.ModernUI is whatever it is supposed to be?

If it works on your machine but not on the users then the most likely explanation is that you’re not delivering some component of modernui or you’re delivering it to the wrong place.

Hope that helps.

This may always be related to the deployment of Application.

You may have missed some of the resources or dll, image , font, or others needed for the program . so try to check the application Include file .

In addition, you can try to trap unhandled exceptions at different levels in WPF:

1. AppDomain.CurrentDomain.UnhandledException From all threads in the AppDomain.
2. Dispatcher.UnhandledException From a single specific UI dispatcher thread.
3. Application.Current.DispatcherUnhandledException From the main UI dispatcher thread in your WPF application.
4. TaskScheduler.UnobservedTaskException from within each AppDomain that uses a task scheduler for asynchronous operations.

I’ve been hacking away at this and not really making a lot of progress. I think I’ve finally got the issue with ModernUI resolved; at least its no longer complaining about that. But now I can no longer run the app from within Visual Studio! Now I’m getting errors like this:

System.Windows.Markup.XamlParseException occurred
HResult=-2146233087
LineNumber=16
LinePosition=18
Message=’Set property ‘System.Windows.ResourceDictionary.Source’ threw an exception.’ Line number ’16’ and line position ’18’.

InnerException:

Notice the inner exception about Assets/CoreFrameworkResources.xaml. I thought I’d look further into that, thinking that maybe I’d have to use a Pack URI syntax instead. So I found this Microsoft Docs document which I used to modify how our customized resource dictionary should be referenced within App.Xaml. So, I changed the App.xaml to now look like this:

But this change didn’t help, either. Now I’m getting this error:

Код в App.xaml

<Application x:Class=«APP.App»

xmlns=«http://schemas.microsoft.com/winfx/2006/xaml/presentation»

xmlns:x=«http://schemas.microsoft.com/winfx/2006/xaml»

xmlns:local=«clr-namespace:APP»

StartupUri=«MainWindow.xaml»>

<Application.Resources>

<ResourceDictionary>

<ResourceDictionary.MergedDictionaries>

<ResourceDictionary Source=«Data/Theme/Light.xaml»/>

</ResourceDictionary.MergedDictionaries>

</ResourceDictionary>

</Application.Resources>

Добавил Data/Theme/Light.xaml в ресурсы. Запускаю, и ошибки:

• Необработанное исключение типа «System.Windows.Markup.XamlParseException» в PresentationFramework.dll
• «Задание свойства «System.Windows.ResourceDictionary.Source» вызвало исключение.»: номер строки «9» и позиция в строке «18»

Как исправить?

Измените StartupUri=»MainWindow.xaml» на StartupUri=»FolderName/MainWindow.xaml»

Решил мою проблему, когда я переместил MainWindow в папку просмотра

Это случилось со мной несколько раз — всегда, когда я переместил MainWindow.xaml в другую папку и забыл обновить StartupUri в App.xaml

Visual Studio каким-то образом переименовала мой MainWindow.xaml в MainWindow(1).xaml, поэтому я снова переименовал его в MainWindow.xaml

В моем случае мне нужно было использовать синтаксис URI пакета, чтобы установить свойство SrartUpUri моего файла App.xaml, чтобы указать на новое местоположение моего MainWindow.xaml, так как:

<Application x:Class=«TrafficLights.Controller.App»

xmlns=«http://schemas.microsoft.com/winfx/2006/xaml/presentation»

xmlns:x=«http://schemas.microsoft.com/winfx/2006/xaml»

StartupUri=«pack://application:,,,/View/MainWindow.xaml»>

Подробнее о URI пакетах здесь:

http://msdn.microsoft.com/en-us/library/aa970069(v=vs.110).aspx

<Window.Resources/>

In the XAML file you are working on add the following code if the Resource.Dictionary is named StylesDictionary.xaml and is located in a root directory called Styles.  The Project name is called MyProjectWPF_GUI.

<Resource.Dictionary/>

The Resource.Dictionary looks like the following.  Its filename is called StylesDictionary.xaml and is under a directory called Styles.

Good Luck

In general this issue is caused when a referenced resource cannot be found.

<Application x:Class="AppName.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             StartupUri="MainWindow.xaml">
    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="/PresentationFramework.Aero;component/themes/Aero.NormalColor.xaml"/>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>
</Application>

In my specific circumstance, as the xaml above details, this issue was caused by a reference to PresentationFramework.Aero DLL that was not contained in the output bin folder of the compiled project. Under references, setting Copy Local to true did the trick for me.
