Question activity could not be loaded because of errors in the xaml

[meysam-karimi]

I tried to write and run windows workflow tutorial examples, When I open an activity (XAML file), The following error will be seen:

activity could not be loaded because of errors in the xaml

I use Visual Studio 2019 and C# lanquege, I also saw a related question in StackOverflow but couldn't see any error in the XAML file when I opened that with an XML editor.

How do you expect us to see whether there are any errors in the XAML if we can't see the XAML?

In general, you can often diagnose errors by starting out with the simplest code you possibly can, then build it up piece by piece until it breaks. That way, you know the issue is in the last piece you added.

What specific example? Is the xaml file in the example? What xaml file? There are very many things that could be an error in an xaml file that is no error as an xml file.
