MongoDb C# Typed Aggregations with Group Unwind and Project

Question

I have a collection like this:

[{
  \"_id\": 1,
  \"OtherProperties\": 100
  \"PersonInventory\": [{
    \"FirstName\": \"Joe\",
    \"MiddleName\": \"Bob\",         


        

Answer 1

I did some digging on the mongodb Jira pages, it looks like there isn't support for the variable $$ROOT, so the above queries are not supported.
