Aaronontheweb / efcore-patternsEntity Framework Core best practices including NoTracking by default, query splitting for navigation collections, migration management, dedicated migration services, and common pitfalls to avoid.
Aaronontheweb / opentelemetry-net-instrumentationProvides guidance for implementing OpenTelemetry instrumentation in .NET codebases, covering tracing (Activities/Spans), metrics, logs, naming conventions, error handling, performance, SDK setup, resources, context propagation, and API design best practices.
Aaronontheweb / package-managementManage NuGet packages using Central Package Management (CPM) and dotnet CLI commands. Never edit XML directly - use dotnet add/remove/list commands. Use shared version variables for related packages.
Aaronontheweb / playwright-blazor-testingWrite UI tests for Blazor applications (Server or WebAssembly) using Playwright. Covers navigation, interaction, authentication, selectors, and common Blazor-specific patterns.
Aaronontheweb / dotnet-project-structureModern .NET project structure including .slnx solution format, Directory.Build.props, central package management, SourceLink, version management with RELEASE_NOTES.md, and SDK pinning with global.json.
Aaronontheweb / r3-reactive-extensionsBuild reactive/event-driven C# with R3 (Cysharp's modern reimplementation of Reactive Extensions). Covers the Observable<T>/Observer<T> model, the OnErrorResume error contract, async dispatch with AwaitOperation, Task/IAsyncEnumerable integration, TimeProvider/FrameProvider scheduling, the concurren…
Aaronontheweb / akka-net-managementAkka.Management for cluster bootstrapping, service discovery (Kubernetes, Azure, Config), health checks, and dynamic cluster formation without static seed nodes.
Aaronontheweb / akka-net-testing-patternsWrite unit and integration tests for Akka.NET actors using modern Akka.Hosting.TestKit patterns. Covers dependency injection, TestProbes, persistence testing, and actor interaction verification. Includes guidance on when to use traditional TestKit.
Aaronontheweb / aot-trimmingGuidelines for making .NET libraries and applications trimming-safe and Native AOT compatible. Covers the trimming/AOT model, the MSBuild properties that enable analysis (IsTrimmable, IsAotCompatible, PublishTrimmed, PublishAot), the trimming attributes (RequiresUnreferencedCode, RequiresDynamicCode…
Aaronontheweb / aspire-integration-testingWrite integration tests using .NET Aspire's testing facilities with xUnit. Covers test fixtures, distributed application setup, endpoint discovery, and patterns for testing ASP.NET Core apps with real dependencies.
Aaronontheweb / mailpit-integrationTest email sending locally using Mailpit with .NET Aspire. Captures all outgoing emails without sending them. View rendered HTML, inspect headers, and verify delivery in integration tests.
Aaronontheweb / aspire-service-defaultsCreate a shared ServiceDefaults project for Aspire applications. Centralizes OpenTelemetry, health checks, resilience, and service discovery configuration across all services.
Aaronontheweb / crap-analysisAnalyze code coverage and CRAP (Change Risk Anti-Patterns) scores to identify high-risk code. Use OpenCover format with ReportGenerator for Risk Hotspots showing cyclomatic complexity and untested code paths.
Aaronontheweb / api-designDesign stable, compatible public APIs using extend-only design principles. Manage API compatibility, wire compatibility, and versioning for NuGet packages and distributed systems.
Aaronontheweb / modern-csharp-coding-standardsWrite modern, high-performance C# code using records, pattern matching, value objects, async/await, Span<T>/Memory<T>, and best-practice API design patterns. Emphasizes functional-style programming with C# 12+ features.
Aaronontheweb / csharp-concurrency-patternsChoosing the right concurrency abstraction in .NET - from async/await for I/O to Channels for producer/consumer to Akka.NET for stateful entity management. Avoid locks and manual synchronization unless absolutely necessary.
Aaronontheweb / csharp-nullable-reference-typesGuidelines for introducing and using nullable reference types (NRT) and System.Diagnostics.CodeAnalysis nullable attributes in C# / .NET codebases.
Aaronontheweb / type-design-performanceDesign .NET types for performance. Seal classes, use readonly structs, prefer static pure functions, avoid premature enumeration, and choose the right collection types.
Aaronontheweb / dotnet-local-toolsManaging local .NET tools with dotnet-tools.json for consistent tooling across development environments and CI/CD pipelines.
Aaronontheweb / microsoft-extensions-configurationMicrosoft.Extensions.Options patterns including IValidateOptions, strongly-typed settings, validation on startup, and the Options pattern for clean configuration management.
Aaronontheweb / dependency-injection-patternsOrganize DI registrations using IServiceCollection extension methods. Group related services into composable Add* methods for clean Program.cs and reusable configuration in tests.
Aaronontheweb / mjml-email-templatesBuild responsive email templates using MJML markup language. Compiles to cross-client HTML that works in Outlook, Gmail, and Apple Mail. Includes template renderer, layout patterns, and variable substitution.
Aaronontheweb / playwright-ci-cachingCache Playwright browser binaries in CI/CD pipelines (GitHub Actions, Azure DevOps) to avoid 1-2 minute download overhead on every build.
Aaronontheweb / sdk-container-publishingPublish .NET services as container images with the built-in SDK tooling (dotnet publish /t:PublishContainer, Microsoft.NET.Build.Containers) - no Dockerfile required. Covers the MSBuild property surface, base-image inference, self-contained and AOT implications, and CI/CD publishing.
Aaronontheweb / serializationChoose the right serialization format for .NET applications. Prefer schema-based formats (Protobuf, MessagePack) over reflection-based (Newtonsoft.Json). Use System.Text.Json with AOT source generators for JSON scenarios.
Aaronontheweb / dotnet-slopwatchUse Slopwatch to detect LLM reward hacking in .NET code changes. Run after every code modification to catch disabled tests, suppressed warnings, empty catch blocks, and other shortcuts that mask real problems.
Aaronontheweb / snapshot-testingUse Verify for snapshot testing in .NET. Approve API surfaces, HTTP responses, rendered emails, and serialized outputs. Detect unintended changes through human-reviewed baseline files.
Aaronontheweb / testcontainers-integration-testsWrite integration tests using TestContainers for .NET with xUnit. Covers infrastructure testing with real databases, message queues, and caches in Docker containers instead of mocks.
Aaronontheweb / verify-email-snapshotsSnapshot test email templates using Verify to catch regressions. Validates rendered HTML output matches approved baseline. Works with MJML templates and any email renderer.
Aaronontheweb / aspire-configurationConfigure Aspire AppHost to emit explicit app config via environment variables; keep app code free of Aspire clients and service discovery.
