Single database and user Belongs to a tenant. This worked perfect until this week when we deployed on Sunday but there are no code changes related to tenacy and we have not updated the framework.
The only change is the build agents are now running the latest 3.1 and core is weird in that if you do not specify the SDK version it will try to build with the latest SDK.
There are breaking changes to the way multi-tenancy works in 3.1 but I havne't been able to dig into the base code to figure out how it uses multi-tenancy in the middlware. https://michael-mckenna.com/multi-tenancy-compatibility-dot-net-core-three
Thanks! that was exactly what I was looking for.
