How to recover xaml from baml?

Question

WPF

Good afternoon. Using the reflector, I got the application code, then using the BAML Viewer plugin for it, I got the xaml. I threw this xaml project - in the designer it looks like it should, but it refuses to compile with the error:
Error 1 MyClass cannot be the root of a XAML file because it was defined using XAML.
What to do with it?

As far as I understand from the above code, you need to write like this:

<Window x:Class="ссылка на класс Login" ...>
...
</Window>
