📝 Walkthrough

Walkthrough

This PR upgrades the Papercut SMTP solution from .NET 9.0 to .NET 10.0 across all projects—examples, core libraries, and tests—with coordinated NuGet package version updates. Two code changes enhance cancellation handling in rule execution and refine the reactive scheduler in theme monitoring.

Example projects framework and dependencies examples/SendEmailTest/*.csproj, examples/SendEmailTestWithBadSSL/*.csproj, examples/SendEmailWithFileLinks/*.csproj, examples/SendEmailWithPdfAttachment/*.csproj, examples/SendEmailWithTls/*.csproj, examples/SendRichEmailTest/*.csproj, examples/SendWordWrapTest/*.csproj	All seven example projects transition to net10.0 with pinned NuGet versions: MailKit/MimeKit to 4.17.0, Microsoft.Extensions.Configuration variants to 10.0.9.
Core library projects framework and dependencies src/Papercut.Common/*.csproj, src/Papercut.Core/*.csproj, src/Papercut.Infrastructure.IPComm/*.csproj, src/Papercut.Infrastructure.Smtp/*.csproj, src/Papercut.Message/*.csproj, src/Papercut.Rules/*.csproj, src/Papercut.Service.TrayNotification/*.csproj, src/Papercut.Service/*.csproj, src/Papercut.UI/*.csproj	Eight core libraries upgrade target framework from net9.0 to net10.0. NuGet updates span mail handling (MailKit, MimeKit, SmtpServer), DI containers (Autofac, Autofac.Extensions.DependencyInjection), reactive extensions (System.Reactive 6.1.0), logging/sinks (Serilog variants), configuration, and system packages.
Test projects framework and dependencies test/Papercut.Core.Tests/*.csproj, test/Papercut.Infrastructure.Smtp.Tests/*.csproj, test/Papercut.Message.Tests/*.csproj, test/Papercut.Rules.Tests/*.csproj	Five test projects upgrade to net10.0 and refresh test infrastructure: NUnit (4.4.0 → 4.6.1), Microsoft.NET.Test.Sdk (18.0.0 → 18.6.0), NUnit3TestAdapter (5.2.0 → 6.2.0), and AwesomeAssertions (9.2.0 → 9.4.0).
Code compatibility adjustments src/Papercut.Rules/App/RulesRunner.cs, src/Papercut.UI/AppLayer/Themes/ThemeManagerService.cs	RunNewMessageRules adds token.ThrowIfCancellationRequested() check during enabled-rule iteration. ThemeManagerService system theme subscription changes from RxApp.MainThreadScheduler to RxSchedulers.MainThreadScheduler for reactive scheduling.

Poem

🐰 From dot-net nine to ten we hop,
Dependencies dance, frameworks don't stop—
Cancellation tokens and schedulers align,
The upgrade pipeline runs so fine!
A rabbit's work, with patience and care,
Builds faster software everywhere! 🚀
