Start in the pizza-pricing exercise tests and inspect the final Order price for gigantic order case, which currently uses List.replicate 100_000 Margherita. Run dotnet test on the completed files and verify the test suite completes successfully without the transport-connection abort while retaining the expected pricing result.
Written by the indexing model from the issue text.
Description
Running dotnet test on the completed files for the pizza-pricing exercism fails because of the volume of tests generated in the last test case Order price for gigantic order with:
Test Run Aborted with error System.Exception: One or more errors occurred.
---> System.Exception: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host..
---> System.Exception: An existing connection was forcibly closed by the remote host.

Reducing the number of items generated will run and pass, for example:
from:
let ``Order price for gigantic order``() = orderPrice (List.replicate 100_000 Margherita) |> should equal 700_000
to:
let ``Order price for gigantic order``() = orderPrice (List.replicate 10_000 Margherita) |> should equal 70_000
