      Summary

      I can do this like on linq2 but error on linq3

      public Task<long> UpdateEntityAsync(long id, Expression<Func<T, object>> exp, object value, Dictionary<string, object> update, MonTrans? monTrans = null, UpdateOptions? options = null)
{
   var filter = Builders<T>.Filter.And(GetPkMatch(id), Builders<T>.Filter.Eq(exp, value));
   var res = await collection.UpdateOneAsync(filter, new BsonDocument("$set", new BsonDocument(update), options));
   return res.ModifiedCount;
}
