This PR adds comprehensive ASP.NET Core release notes for .NET 10 Preview 7, documenting all major features and improvements in the release.

What's New in ASP.NET Core .NET 10 Preview 7

The release notes cover the following features and improvements:

🔧 Configure suppressing exception handler diagnostics

  • New ExceptionHandlerOptions.SuppressDiagnosticsCallback option for controlling diagnostic output
  • Updated default behavior to not log exceptions handled by IExceptionHandler
  • Addresses user feedback about unwanted error-level logging for handled exceptions

🔐 Avoid cookie login redirects for known API endpoints

  • API endpoints now return 401/403 status codes instead of redirecting to login pages
  • Automatic detection of API endpoints using new IApiEndpointMetadata interface
  • Highly requested feature that improves API authentication behavior

🔑 Passkey authentication improvements

  • Simplified APIs for passkey authentication in ASP.NET Core Identity
  • Built-in passkey support in Blazor Web App project template (dotnet new blazor -au Individual)
  • Updated to resemble what will ship in .NET 10 GA
  • Details on API changes from Preview 6 for upgrade guidance

🌐 Support for .localhost top-level domain

  • Full support for *.localhost domains in Kestrel server binding
  • Updated HTTPS development certificates to support *.dev.localhost
  • New --localhost-tld option in project templates for better local development

⚡ Use PipeReader support in System.Text.Json

  • Performance improvements for JSON deserialization in MVC and Minimal APIs
  • Automatic usage of new PipeReader support without code changes
  • Guidance for fixing custom JsonConverter implementations

📋 Enhanced validation for classes and records

  • Support for validation attributes on both classes and records
  • Consistent code generation and validation behavior
  • Enhanced flexibility when designing models using records

🔥 Blazor improvements

  • Resource preloader component renamed from LinkPreload to ResourcePreloader
  • Updated JavaScript APIs: Blazor.pauseCircuit() and Blazor.resumeCircuit()
  • Simplified C# attribute: PersistentStateAttribute
  • Enhanced NotFound support for custom routers
  • Improved diagnostic metrics and traces following OpenTelemetry conventions
  • WebAssembly host builder service provider configuration for better DI validation

📊 OpenAPI.NET dependency upgraded to stable release

  • Upgrade to Microsoft.OpenApi v2.0.0 (GA)
  • Multiple bug fixes and community contributions

All obsoletions are documented as breaking changes, which we then link to from here. No need to list them inline.
