From .NET to TypeScript.
After 7 years of .NET across IBM and Daikin, I rebuilt my delivery stack on Next.js. Here is the migration playbook.
.NETTypeScriptNext.jsMigration
C# developers already think in types. TypeScript structural types map 1:1 to interfaces. Generics and LINQ patterns translate directly to modern array methods.
- LINQ → Array.map/filter
- MVC → Server Components
Favor composition over deep OOP hierarchies. Trade System.Reflection for compile-time Zod schemas. Retrain for async-first I/O.
Days 1-30: Fundamentals. Days 31-60: Pattern Mapping. Days 61-90: Production auth, DB, and deployment.
“The migration isn't about abandoning .NET. It's about adding a second language to your delivery toolkit to bridge the gap between legacy systems and modern interfaces.”
