Unable to import models in service interface

Hi im learning Dependency Injection for the first time and making a micro-project to try it out. But I have a model class in my main project and a class from that model is needed in the service interface however im unable to import the model class in the interface.

namespace ASPNETCoreLearn2.Models
{
    public class CityWeather
    {
        public string CityUniqueCode { get; set; }
        public string CityName { get; set; }
        public DateTime DateAndTime { get; set; }
        public int TemperatureFahrenheit {  get; set; }
    }
}

namespace ASPNETCoreLearn2.Models
{
    public class CityWeather
    {
        public string CityUniqueCode { get; set; }
        public string CityName { get; set; }
        public DateTime DateAndTime { get; set; }
        public int TemperatureFahrenheit {  get; set; }
    }
}

using ASPNETCoreLearn2.Models; //TYPE OR NAMESPACE COULD NOT BE FOUND
namespace ServiceContracts
{
    public interface IWeatherService
    {
        public List<CityWeather> GetWeatherDetails();
    }
}

using ASPNETCoreLearn2.Models; //TYPE OR NAMESPACE COULD NOT BE FOUND
namespace ServiceContracts
{
    public interface IWeatherService
    {
        public List<CityWeather> GetWeatherDetails();
    }
}

I can import ServiceContracts in ASPNETCoreLearn2 but i can't do vice-versa even though ive properly added the project dependencies.

        Console.WriteLine("BUTTON ETNEENTTERR");
    }
}

private void Button_MouseLeave(object sender, RoutedEventArgs e)

private void Button_MouseEnter(object sender, RoutedEventArgs e)
{
    if (sender is Button button)

}

private void Button_MouseLeave(object sender, RoutedEventArgs e)
{
    if (sender is Button button)
    {
        button.Background = Brushes.Transparent;

✅ Image source not being set with C#, WPF

I have a very basic C# statement but whenever it gets executed the image is not set and the image element disappears.

qrcode.Source = new BitmapImage(new Uri(@"/Images/scannn.png", UriKind.Relative));

qrcode.Source = new BitmapImage(new Uri(@"/Images/scannn.png", UriKind.Relative));

I have no clue why its not being set, the image is present in that directory, build action of the image is set to content and copy to output is set to copy always

✅ WPF TTS plays before text updates

mainText.Text = (string)reader.Value;
                        if (autoplayVar) 
                        {
                            PlayTTS(mainText.Text);
                        }

mainText.Text = (string)reader.Value;
                        if (autoplayVar) 
                        {
                            PlayTTS(mainText.Text);
                        }

The above code is inside a button click event. I want the mainText.Text to update before the TTS plays because when it starts playing the mainText.Text doesn't updates to reader.Value until the TTS has stopped playing
