We currently working for automatical weighing system. Using C#, .NET, MVVM, WPF and XAML. When we start application, we log in and then menu show with some agendas and modules. I got a new computer in company, so I installed few things and Visual Studio 2019. I had 2015 version on my old pc. Installation was succesfull. Problem is, when I click on some agenda or modul in the menu.

Sometimes it opens correctly, but often it end on

InvalidOperationException: Cannot work with Freezable System.Windows.Shell.WindowChrome in threads, because it cannot be freezed.

That exception happend in xaml.cs, in this piece of code:

public DWTimeWindowDetail()
{
    InitializeComponent(); - here is a exception
}

Maybe there is a problem in Visual Studio 2019, because in 2015 it never happend.

Is it "treads" or "threads"? – Uwe Keim Aug 08 '19 at 05:50
@UweKeim Threads. My mistake. – Daniel Capek Aug 08 '19 at 05:51
@UweKeim It is perhaps the same, but it also not. I tried the solution they write in answers, but it didn´t help. :/ – Daniel Capek Aug 08 '19 at 06:02
