I am using WPF Form Application in C # programming language. I have homework about MVP (Models-View-Presenter). I found a sample project in the Windows Form Application in C # language. I wrote the codes in the sample project to my own project. But I got a few errors. There is no change in the codes I share, I wrote the same.

In summary; Convert the same codes to WPF.

Windows Form Applicaton in C # >>>>>> WPF Form Application in C # It needs to be transformed.

PLACES I HAVE FAILED;

*** There is an error in the "RectanglePresenter" code in "RectanglePresenter.cs".

ERROR: Inconsistent accessibility: The 'Rectangle' parameter type is less accessible than the 'Rectangle Presenter.Rectangle Presenter (Rectangle)' method.

*** "Return lblArea.Text;" in "MainWindows.cs" and "lblArea.Text = value;" There are two errors.

ERROR: The 'Label' does not contain a 'Text' definition and no accessible 'Text' extension method was found that accepts a first argument of type 'Label' (could your use-directive or compilation reference be missing?)

I want the screen output as in the picture below. BUT must be created by applying MVP(Model-View-Presenter).

I would be glad if you solve minor mistakes. Thank you from now.
