‘Provide value on ‘System.Windows.Baml2006.TypeConverterMarkupExtension’ threw an exception.’

The exception in the title is thrown when I open a window in WPF, the strange thing is that this does not happen on my Windows 7 development machine nor does it happen when it is deployed on Windows 7.

I only get this error on Windows XP, and only the second time that I open the window.

Here is the code to open the window:

And the XAML for the window:

Does anyone have suggestions?

The solution is quite a weird one but I have it figured out.

I realized that the error was occurring on the InitializeComponent() of the window, I then added a try catch to the constructor and showed the InnerException of the Exception.

The error that I received is «Image format not recognized».

I have no idea why this happens only on XP and the second time that the window is shown but by replacing my .ico with a .png the problem was resolved.

Hope this helps someone.

I just ran into this issue as well. I know this is old, but what I had to end up doing was set the images to Resource, and Copy Always. only by browsing my /bin/Debug folder did I realize that the images were not at a valid path location

This problem can also occur if the required image is not available at the specified location. So Check the inner exception and add any image that might have been missed or misspelled.

I got this error because my Command Binding of a Button was wrong:

You Should first Import Image to your project Solution Explorer — Show All

then Right Click on the image and select Include

In my case the root cause was wrong BuildAction property on all images. I fixed it by changing BuildAction from Content to Resource.

I got this exception after moving my Resource Dictionary from root of my application to a subdirectory. In my case the problem were Image paths inside my Style setters inside the dictionary. After I preceded them with a forward slash ‘/’, the application started to work again. If you’re having a similar problem, open the resource dictionary, and the error will be highlighted with the blue ‘squiggly’ line.

In my case, I have added ‘WpfToolkit’ refrence to my module, and there is no need. After deleting this reference, everything was ok. Strange!

Just go to Project>[Your Project Name] Settings and set your .ico file as icon now your .ico file is mentioned in your manifest file and you can simply include your .ico file in your XAML file using

In my case, I found the mew added icon(image) file is not added into my project. It is resolved after I added these new image files into my project, not just file copy.

In my case the files existed on disk but were not referenced in the project. I added them to the project but the error persisted despite reloading the solution and restarting Visual Studio.

I changed the references to an existing file that was already in the project and it ran fine (albeit with the wrong graphic). I then changed it back to the original reference and it ran fine again but with the correct image. Presumably the error was getting cached somehow until it was flushed out of the system.

Remove the «WPFToolkit» reference from your cs.proj file.

It should do the trick.

copy and paste the file name is changed. that’s why I get this error.

well, in my case I added the new photos to the image Folder in FileExplore while image folder was added to the project while ago. and there wasn’t any problem with the image path in the project. but when I build the project I face to the same error. then I add those new photos to project by right click on the image folder and add the existing item and selected new photos. then I cleaned the solution and build it again.

There are many ways to cause this issue. Since the exception isn’t specific. Here is a list of solutions to try from this thread.

Firstly, you can try/catch the InitializeComponent() call which is throwing the exception to get more details about what happened.

• If the image is an icon (.ico) file use an image (.png) or equivalent instead
  • In some cases .ico files are problematic — I was using .NETCore

  Make sure your image file has a build action of Resource or Embedded Resource

  The resource files described in this section are different than the resource files described in XAML Resources and different than the embedded or linked resources described in Manage Application Resources (.NET). — MSDN

  Ensure your reference to the file is spelled and pathed correctly

  System.Windows.Baml2006.TypeConverterMarkupExtension

  Здравствуйте, у меня действительно есть проблема, которая, похоже, есть у многих людей, но я попробовал предложенные решения, и они не сработали. У меня есть этот код, который всегда вызывает исключение (сообщение: «Provide value on ‘System.Windows.Baml2006.TypeConverterMarkupExtension’ thrown an exception») в методе Window.InitializeComponent(). Вот мой код Xaml:

  Я не знаю, что делать. Надеюсь, вы сможете помочь.

  1 ответ

  Я написал этот код:

  Скорее всего, у вас нет изображений, расположенных в папке Resources.

  Убедитесь, что следующие вещи действительны для обоих изображений (Rock.png и Peanut.png) , используемых в вашем XAML:

  1. Изображение added in project under Resources folder в том же проекте.
  2. Build Action для изображения установлено значение Resource .

  Кроме того, вы можете попробовать использовать более подробное определение Pack URI:

  «pack://application. /SimpleMoving;component/Resources/Peanut.png» и «pack://application. /SimpleMoving;component/Resources/Rock.png» , где SimpleMoving-это имя вашего assembly.

  Seems you’re using kinda markup extension. Does that markup extension is implemented by yourself? I remember that the custom MarkupExtension requires you to implement a member method ProvideValue, and seems the exception is on that stack.

  You sometimes get this error when you use some image (icon in your case) in xaml but have forgotten to include in your project. You must have copied the image in that directory externally but have not yet included it in your project.

  Not the answer you’re looking for? Browse other questions tagged c# wpf exception or ask your own question.

  Question

  

  

  I am using Visual Studio 2010 and have a WPF project. Everything works great, EXCEPT when I deploy to a Windows XP SP3 machine. I receive this error: Provide value on ‘System.Windows.Baml2006.TypeConverterMarkupExtension’ threw an exception.

  I have been trying to figure this out for days and have Googled so many things. Everything, so far, that I’ve seen suggested, I’ve tried to no avail.

  Does anyone have any insight on this issue?

  Thanks so much for your time!

  I recently got this error myself. What it tured out to be for me was I was using a ImageBrush as a static resource. The image file image.png that i had set to the bursh was not in the correct directory. Everything compiles and for some reason i got no errors in my build. When i went to deploy my application i got the ‘System.Windows.Baml2006.TypeConverterMarkupExtension’ threw an exception. as well. So I would guess that your problem is something not mapping correctly in xaml and in runtime its not found when requested. Hope this helps

  

  

  I had tried that earlier, but that didn’t fix it either, sadly. I’ll just stick with 3.5 .NET Framework, until my clients upgrade to Windows 7 🙂

  

  

  I’ve had this error message appear when running certain WPF applications running XP sp3.

  The fix in my case was to check the icon (.ico) files being used by any of your windows in your application.

  It turned out that having a 256 * 256 32bit png image in the icon file used by the application window was causing the problem. Deleting that image, leaving the other icon types solved the problem.

  

  

  Try adding a try..catch around the contents of your initialization routine or your main entrypoint function, and inside the catch block dig down to the innerException to get a much nicer error message about what caused the parser to throw its wrapper exception. When I do that, it usually tells me something like «ImageFormat not supported» along with some info about the element that was being parsed. From there it is usually quite easy to go straight to the offending Xaml block and fix it.

  So wrap a try..catch around your highest level, and in the catch block pop up an alert box with the top level exception’s message *and also* the innerException’s message. The innerException often points straight to the heart of the issue.
