Research direction

Start with the C# JSON construction snippet in the issue and reproduce the exception around the Console.WriteLine(rss.ToString()) entry point. There is no repository file or test identified; done would require establishing the intended JSON shape, determining why the shown construction fails, and documenting a verified resolution.

Written by the indexing model from the issue text.

Description

This is my C# JSON code:

Object rss =
new JObject(
new JProperty("Products",
new JObject(
from c in Categories
select new JObject(
new JProperty("ProductCategoryID", c.CategoryID),
new JProperty("Category", c.Name),
new JProperty("psc",
new JArray(
from sc in Subcategories
where sc.CategoryID == c.CategoryID
select new JObject(
new JProperty("ProductSubcategoryID", sc.SubcategoryID),
new JProperty("SubCategory", sc.Name),
new JProperty("p",
new JArray(
from p in Products
where p.scID == sc.SubcategoryID
select new JObject(
new JProperty("Item", p.Name),
new JProperty("ProductID", p.ProductID),
new JProperty("ListPrice", p.ListPrice)))))))))));

        Console.WriteLine(rss.ToString());
