I had an strange Bug in my application. Whenever the AboutDialog would be displayed the companylogo on the mainwindow vanished.
I have the discovered that this is related to multiple windows using the same resource simultaneous. In my testapplication I am starting two windows like this:
void App_Startup(object sender, StartupEventArgs e)
{
MainWindow mainWindow = new MainWindow();
mainWindow.Top = 100;
mainWindow.Left = 900;
mainWindow.Show();
}
On my Mainwindow I am using a ContentPresenter with a path stored as Application resource. This does not happen with a string. But my logo is only displayed on one Window.
<StackPanel>
<ContentPresenter x:Name="Logo" Content="{DynamicResource BrandingLogo}" Margin="20" HorizontalAlignment="Center"/>
<TextBox Text="{DynamicResource MyConstString}"/>
</StackPanel>
Does anyone have an idea how to fix this?
Edit:
In my real-world-application my logo is stored in a ResourceDictionary so it is not possible to set x:Shared to false.
