var applicationDirectory = System.IO.Path.GetDirectoryName(assemblyLocation);
var imagesDirectory = System.IO.Path.Combine(applicationDirectory, "img");
var contact_photo = Directory.EnumerateFiles(imagesDirectory,
    "*.jpg",SearchOption.TopDirectoryOnly);
if (contact_photo != null)
{
   foreach (var photo in contact_photo)
   {
      Console.WriteLine(photo);

      File.Delete(photo);
   }

}

Error Message:

Before deleting the images, did you review your usage of those images?

Other parts of your WPF app may lock them when you don't notice,

Refer to this answer https://stackoverflow.com/a/1025446/988830

The file is used by another process and you have to make sure the process which has hold the file has released it. If it is not in your control then you need to you try catch block to avoid exception and you cannot do more than that.

try
{
    //Delete file
}
catch (Exception ex)
{
    Console.WriteLine(ex.Message.ToString());
}
