ASP.NET Core .NET 9 New Features — Complete Guide — ShopNest Capstone
Article 75 of 75 · Module 10: Advanced Topics · ShopNest Upgrade to .NET 9
Target keyword: asp.net core 9 new features · Read time: ~30 min · .NET: 8 / 9 · Project: ShopNest Upgrade to .NET 9

Introduction

Graduate ShopNest to .NET 9 — OpenAPI improvements, Blazor updates, SignalR gains, HybridCache, performance wins, and a safe migration checklist from .NET 8.

After this article you will

  • Summarize ASP.NET Core 9 highlights
  • Migrate ShopNest using dotnet upgrade assistant
  • Adopt HybridCache where applicable
  • Review breaking changes
  • Plan production rollout

Prerequisites

Architecture & design

Key .NET 9 / ASP.NET Core 9 highlights

  • HybridCache — L1 memory + L2 distributed (Redis) unified API
  • OpenAPI — improved built-in document generation
  • Blazor — further Blazor United enhancements
  • Performance — faster JSON, LINQ, GC improvements (benchmark your app)
  • Minimal APIs — new binding and filter improvements
// HybridCache (.NET 9)
builder.Services.AddHybridCache(options =>
{
    options.DefaultEntryOptions = new HybridCacheEntryOptions
    {
        Expiration = TimeSpan.FromMinutes(10),
        LocalCacheExpiration = TimeSpan.FromMinutes(2)
    };
});

// Migration
// dotnet tool install -g upgrade-assistant
// upgrade-assistant upgrade ShopNest.sln

Hands-on build guide — ShopNest Upgrade to .NET 9

  1. Retarget all projects to net9.0.
  2. Run full test suite; fix obsolete API warnings.
  3. Replace IMemoryCache+Redis dual usage with HybridCache on catalog.
  4. Deploy to staging slot; smoke test; swap production.
  5. Update GitHub Actions dotnet-version to 9.0.x.

Common pitfalls

  • Skipping staging validation — breaking changes in third-party packages.
  • Mixing net8 and net9 assemblies — retarget all projects together.

Interview & portfolio questions

Q: HybridCache benefit?
A: One API for local + distributed cache tiers — less boilerplate than IMemoryCache + IDistributedCache.

Q: Upgrade strategy?
A: Staging slot → automated tests → swap; keep rollback slot on net8 until stable.

Summary

  • Article 75 completes the 75-lesson ShopNest track
  • .NET 9 keeps ShopNest current for 2025+ hiring
  • HybridCache + OpenAPI upgrades are quick wins
  • Always test before production swap
