Context

While running tests, I encountered an issue where DbContext creation failed with the error:
"Sequence contains more than one matching element."
This made it difficult to identify the root cause of the exception.

Changes

• Improved error handling to detect duplicate enum registrations.
• Updated exception message for better debugging.

Impact

This change helps developers quickly identify and resolve enum registration issues in the future.

Notes

If any changes are needed, I’m happy to make adjustments.
