Overview
The expectation of the client is to use .NET Aspire with Auth0. The Aspire stack is delivered through a collection of NuGet packages that handle specific cloud-native concerns using a micro service architecture. .NET Aspire was recently released in May 21st, 2024 to the general public.
Cause
.NET Aspire does not offer built-in support for handling authentication/authorization with any Identity Provider. There are additional steps to take with Aspire for any authentication to work as expected.
Here is a discussion on this from the Aspire GitHub repo.
Any further clarification on the custom Aspire resource should come from the .NET team.
