In my case this error appeared when I asigned to both dynamic created controls (combobox), same created control from other class.

//dynamic created controls
ComboBox combobox1 = ManagerControls.myCombobox1;
...some events

ComboBox combobox2 = ManagerControl.myComboBox2;
...some events

.

//method in constructor
public static void InitializeDynamicControls()
{
     ComboBox cb = new ComboBox();
     cb.Background = new SolidColorBrush(Colors.Blue);
     ...
     cb.Width = 100;
     cb.Text = "Select window";
        
     ManagerControls.myCombobox1 = cb;
     ManagerControls.myComboBox2 = cb; // <-- error here
}

Solution: create another ComboBox cb2 and assign it to ManagerControls.myComboBox2.

I hope I helped someone.

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

When I had this problem  I had literally just forgot to fill in a parameter value in the XAML of the code  For some reason though  the exception would send me to the CS of the WPF program rather than the XAML  No idea why

It took me ages to work this one out  so for the benefit of searchers   I had a bizarre issue whereby the application worked in debug  but gave the XamlParseException once released   After fixing the x86 x64 issue as detailed by Katjoek  the issue remained   The issue was that a CEF tutorial said to bring down System Windows Interactivity from NuGet  even thought it s in the Extensions section of references in  NET  and bringing down from NuGet sets specific version to true   Once deployed  a different version of System Windows Interactivity was being packed by a different application    It s refusal to use a different version of the dll caused the whole application to crash with XamlParseException
