How to change image on WPF form?

Question

.NET

Good afternoon, comrades!
I have an image on a WPF form

<Image x:Name="MainImage" Source="C:\temp\test.jpg"  HorizontalAlignment="Left" Height="300" Width="450" VerticalAlignment="Top" />

Tell me how to change the Source so that the picture changes on the form?
Got the following method:

Uri uri = new Uri(@"C:\temp\IMG_0690.JPG", UriKind.Relative);
            ImageSource imgSource = new BitmapImage(uri);

            MainImage.Source = imgSource;

But despite the absence of errors during compilation and during execution, the picture does not change.
Perhaps some additional action is required?
Thank you in advance
