SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Software projects often suffer from runtime errors caused by unknown null values and weak typing. This Skill promotes strong typing and proactive checks to catch issues early across C# and TypeScript.

Core Features & Use Cases

  • Nullable reference types enforcement in C# to prevent null dereferences.
  • Static analysis integration for C# (Roslyn) and TypeScript to catch issues at build time.
  • Strong typing patterns including generics, immutable DTOs, and discriminated unions to improve reliability and maintenance.
  • Use cases include codebase migrations to stricter typing, API contract enforcement, and safer cross-language data contracts.

Quick Start

Enable nullable reference types in C#, enable static analysis for both languages, and introduce a small set of strongly-typed DTOs to establish strict contracts.

FAQPage Schema
How do I enforce type-safety and null-safety across C# and TypeScript projects?

To enforce type-safety and null-safety, enable nullable reference types in C# and activate static analysis for both C# and TypeScript. This catches unknown null values and weak typing issues at build time rather than runtime.

What's the best way to prevent null dereferences during a codebase migration to stricter typing?

Preventing null dereferences during a migration requires enabling nullable reference types in C#. This proactive check ensures unknown null values are caught early, improving cross-language maintainability and reliability.

How do I enforce API contract boundaries using strong typing patterns?

Enforce API contract boundaries by introducing strongly-typed, immutable DTOs and discriminating unions. This establishes strict contracts and cross-language data boundaries, preventing runtime errors caused by weak typing.

Can I use Roslyn static analysis to catch TypeScript and C# type errors at build time?

Yes, you can integrate static analysis using Roslyn for C# and TypeScript's built-in static analysis. This catches type-safety and null-safety issues at build time, preventing runtime errors before deployment.

Does this approach require enabling nullable reference types and generics for cross-language data contracts?

Yes, enforcing strict cross-language data contracts requires enabling nullable reference types in C# and adopting strong typing patterns like generics and immutable DTOs to ensure reliability and maintenance.

Why do software projects suffer from runtime errors caused by weak typing, and how do I fix it?

Software projects suffer runtime errors from unknown null values and weak typing. Fix this by adopting strong typing patterns, proactive checks, and static analysis to catch issues early across C# and TypeScript.
