Class's ContentPage Question

Hi,

I am trying to create a ContentPage in a MAUI Class Library using the below but it's not working.

namespace MyClass  
{  
    // All the code in this file is included in all platforms.  
    public class MyAuth  
    {  
        public static Page Signin()  
        {  
            Grid grid = new Grid  
            {  
                RowDefinitions =  
                    {  
                        new RowDefinition { Height = new GridLength(50) },  
                        new RowDefinition { Height = new GridLength(1, GridUnitType.Star) },  
                        new RowDefinition { Height = new GridLength(1, GridUnitType.Auto) }  
                    }  
            };  
  
            return new ContentPage  
            {  
                Content = grid;  
            };  
        }  
    }  
}  

Kindly help..

Thanks,
Jassim
