Hi
When i ran the build of the code below it shows this error

"Error 1 The non-generic type 'Newtonsoft.Json.JsonConvert' cannot be used with type arguments"

Kindly help with an appropriate solution

Class:

public class Devotion
{
    public string Date {get; set;}
    public string Title {get; set;}
    public string Verse {get; set;}
 
    [JsonProperty("Read Chapter")]
    public string ReadChapter {get; set;}
 
    [JsonProperty("Read Text")]
    public string ReadText {get; set;}
 
    [JsonProperty("Bible In One Year")]
    public string BibleInOneYear {get; set;}
 
    public string Message {get; set;}
    public string Notes {get; set;}
}

Xaml.cs

private List<Devotion> devotions;
 
public App()
{
   InitializeComponent();
   // as this will be expensive to populate
   // you only want to do it once when the app starts
   devotions = new List<Devotion>();
   AddDevotions();
}
 
protected override void OnNavigatedTo(NavigationEventArgs e)
{
   int index = DateTime.Now.DayOfYear - 1; // list is indexed from 0
   textblock.Text = devotions[index].Message; // or some other property
}  
 
private void AddDevotions()
{
   for(int i = 1; i <= 366; i++)
   {
      string filePath = "Assets/Dec" + i.ToString() + ".js";
      Devotion d = ReadJsonFile(filePath);
      devotions.Add(d);
   } 
}
 
public Devotion ReadJsonFile(string JsonfilePath)
{
   Devotion d = null;
 
   using (StreamReader r = new StreamReader(JsonfilePath))
   { 
      string json = r.ReadToEnd();
      d = JsonConvert<Devotion>.DeserializeObject(json);
   }
   return d; 
}

Thank you in advance and reply soon
