Toolbox button not creating Event Handler

[Ann Maybury]

I crated a project many ways and still get an error when I try to add a button. My latest try was using


When I used the toolbar to add a button and then added the click as shown in the mainWindow.xaml file, the event handler did not appear in the main window.xaml.cs file. What frameworks should I select to poduce a desktop application using C#? This project has just been started and the only addition is the button that is not working. I am using Visual Studio 16.5 but had this same problem with 16.4.x.

Copies of the error message, the xsml code and the xaml.cs code are shown below.

Thanks in advance for any help. ann.maybury@gmail.com
