Over the years, I've learned one critical lesson: The long-term success of a .NET project is decided in the first few days.
When I start a new Web API project, I don't begin with features. I begin with architecture, discipline, resilience, observability, and quality enforcement.
This is the exact template I use for every project — freelance, SaaS, or enterprise. This is not optional. 𝐓𝐡𝐢𝐬 𝐢𝐬 𝐦𝐲 𝐛𝐚𝐬𝐞𝐥𝐢𝐧𝐞 𝐬𝐭𝐚𝐧𝐝𝐚𝐫𝐝.
Here's what every project gets from Day 1:
𝐅𝐨𝐮𝐧𝐝𝐚𝐭𝐢𝐨𝐧 & 𝐁𝐮𝐢𝐥𝐝 𝐃𝐢𝐬𝐜𝐢𝐩𝐥𝐢𝐧𝐞
• Enterprise-grade Directory.Build.props with centralized configuration
• .NET 10 with latest C# features
• Nullable reference types enforced
• Warnings treated as errors
• Code analyzers: SonarAnalyzer, Meziantou, Roslynator
𝐂𝐨𝐝𝐞 𝐐𝐮𝐚𝐥𝐢𝐭𝐲 & 𝐂𝐨𝐧𝐬𝐢𝐬𝐭𝐞𝐧𝐜𝐲
• .editorconfig with strict formatting rules
• Enforced via dotnet format in CI/CD
• Centralized dependency management (Directory.Packages.props)
• Global using statements for cleaner code
𝐀𝐫𝐜𝐡𝐢𝐭𝐞𝐜𝐭𝐮𝐫𝐞 & 𝐃𝐞𝐬𝐢𝐠𝐧
• Clean/Layered/Vertical Slice Architecture (context-dependent)
• Architecture tests to prevent erosion
• FluentValidation for centralized validation
• Custom guard clauses for domain integrity
• Fluent API for EF Core configurations
𝐒𝐞𝐜𝐮𝐫𝐢𝐭𝐲 & 𝐂𝐨𝐦𝐩𝐥𝐢𝐚𝐧𝐜𝐞
• ASP.NET Core Identity with role & permission management
• JWT-based authentication
• EF Core interceptors for audit trails (CreatedBy, UpdatedBy, timestamps)
• Secure audit logging for regulatory compliance
𝐑𝐞𝐬𝐢𝐥𝐢𝐞𝐧𝐜𝐞 & 𝐏𝐞𝐫𝐟𝐨𝐫𝐦𝐚𝐧𝐜𝐞
• API rate limiting
• Retry policies with exponential backoff
• Timeout policies for external dependencies
• Hybrid caching (in-memory + distributed)
• Manual mapping for performance and clarity
𝐎𝐛𝐬𝐞𝐫𝐯𝐚𝐛𝐢𝐥𝐢𝐭𝐲 & 𝐌𝐨𝐧𝐢𝐭𝐨𝐫𝐢𝐧𝐠
• Structured logging with Serilog
• OpenTelemetry for distributed tracing
• Correlation IDs for request tracking
• Health checks (liveness, readiness, database validation)
𝐀𝐮𝐭𝐨𝐦𝐚𝐭𝐢𝐨𝐧 & 𝐓𝐞𝐬𝐭𝐢𝐧𝐠
• xUnit + NSubstitute + FluentAssertions
• Architecture enforcement tests
• GitHub Actions CI/CD pipeline
• Automated build, test, formatting, and deployment
This is not over-engineering. This is engineering done correctly from Day 1.
Professional software must be: Structured. Secure. Resilient. Observable. Automated. Testable. Maintainable.
If the build is clean, the system is stable.
If CI fails, deployment stops.
Without telemetry, production debugging is blind.
This is my standard baseline for building scalable, production-ready .NET systems.
