Expected Behavior
Validation should work correctly.
Steps To Reproduce
The "validation-record-types" project in this repo is a minimal repro of the problem:
https://github.com/mikekistler/dotnet10-issue-repros
The .http file contains a request that will trigger the error.
If you comment out the #define at the top of Program.cs, the project uses a class instead of a record and in this configuration the app works correctly.
