and the stack trace was just helpful but being cryptic.
The Fix:
A simple yet elusive step: remove all <code>bin</code> and <code>obj</code> folders. Once cleared, the tests ran like clockwork again :)

XUnit tests failing after .NET8 upgrade

My journey through trial, error, and discovery as I explore new software tools and libraries. These are notes for future me and for anyone else who might find them useful.
