Please can someone be of help. I encountered this exception below, while trying to compile an XAML code

System.Windows.Markup.XamlParseException HResult=0x80131501 Message='Provide value on 'System.Windows.Baml2006.TypeConverterMarkupExtension' threw an exception.' Line number '40' and line position '22'. Source=PresentationFramework StackTrace: at System.Windows.Markup.XamlReader.RewrapException(Exception e, IXamlLineInfo lineInfo, Uri baseUri) at System.Windows.Markup.WpfXamlLoader.Load(XamlReader xamlReader, IXamlObjectWriterFactory writerFactory, Boolean skipJournaledProperties, Object rootObject, XamlObjectWriterSettings settings, Uri baseUri) at System.Windows.Markup.WpfXamlLoader.LoadBaml(XamlReader xamlReader, Boolean skipJournaledProperties, Object rootObject, XamlAccessLevel accessLevel, Uri baseUri) at System.Windows.Markup.XamlReader.LoadBaml(Stream stream, ParserContext parserContext, Object parent, Boolean closeStream) at System.Windows.Application.LoadComponent(Object component, Uri resourceLocator) at Master_Page_core.MainWindow.InitializeComponent() in C:\Users\deepa\source\repos\Master_Page_core\Master_Page_core\MainWindow.xaml:line 1

This exception was originally thrown at this call stack: [External Code]

Inner Exception 1: IOException: Cannot locate resource 'newfolder1/sidebar.jpg'.

this is the image of error occuring . Click here to see image .

this is xaml code

<Grid.Background>
  <ImageBrush ImageSource="NewFolder1/sidebar.jpg" Stretch="UniformToFill"></ImageBrush>
  </Grid.Background>

I show similar post on this error but it was not helpfull . they asked to include the folder in the project but the Folder containing images is already included in the project.

Have you tried? <ImageBrush ImageSource="NewFolder1/sidebar.jpg" Stretch="UniformToFill" />
