Strange System.InvalidCastException on insert 3.1.0, vs 2017, net4.6.2

I’m don’t understand why exception happens on last insert

using LiteDB;

namespace WindowsFormsApp122
{
 public class dbTestItem
 {
  [BsonId] 
  public int Id { get; set; }
  public int SomeValue { get; set; }
 }

 public static class dbTestItemHelper
 {
  public static bool New(this dbTestItem inItem, LiteRepository inLt)
  {
   return inLt.Insert(inItem);
  }
 }

 static class Program
 {
  static void Main()
  {
   var s = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "TestDb");
   if (File.Exists(s)) File.Delete(s);
   using (var db = new LiteRepository(s)) 
   {
    db.Insert(new dbTestItem()); // ok
    var wtfitem = new dbTestItem();
    wtfitem.New(db); // fail: System.InvalidCastException
   }
  }
 }
}

Your problem lies here:

  public static bool New(this dbTestItem inItem, LiteRepository inLt)
  {
   return inLt.Insert(inItem);
  }

inLt.Insert(inItem) returns the Id of the inserted object, which is of course an int, not a bool. The implicit casting to bool will fail for this reason.
