Why is ValidateScope only true when the Environment is "Development" or "Production"

[haridasnykiel]

Why is this designed this way? In my mind it would make more sense to default the ValidateScope to true and have a configuration that will set it to false if required.

This is the property that validates scope when you start up an application using the WebHostBuilder. When you have a scoped service injected into a singleton service the validation will throw an exception like this:

InvalidOperationException: Cannot consume scoped service '' from singleton

I'm curious about this too. If I ask ChatGPT, it mentions performance, but I can't find any mentioning of that anywhere.
