Question 1

.NET vs Java for enterprise backend development?

Accepted Answer

Both are excellent enterprise choices. .NET 8 offers: superior performance (often 2-3x faster than Java in benchmarks), simpler dependency injection, minimal APIs with less boilerplate, and seamless Azure integration. Java offers: larger enterprise talent pool, Spring ecosystem maturity, and broader cloud provider support. Choose .NET when: your team knows C#, you're on Azure, or performance is critical. Choose Java when: you have existing Spring infrastructure, need maximum cloud portability, or your team has deep JVM expertise.

Question 2

ASP.NET Core vs traditional ASP.NET — what's the difference?

Accepted Answer

ASP.NET Core is the modern, cross-platform, open-source rewrite of ASP.NET. It runs on Windows, Linux, and macOS — not tied to IIS. It's modular (pick only the middleware you need), significantly faster, and actively developed. Traditional ASP.NET (4.x) is Windows-only, IIS-dependent, and in maintenance mode. All new .NET projects should use ASP.NET Core. We exclusively work with .NET 6/7/8 — never the legacy framework.

Question 3

How do your .NET developers handle database migrations in production?

Accepted Answer

EF Core Migrations with code-first approach: generate migration scripts in CI, review SQL output before deployment, apply with idempotent scripts that handle partial failures. For zero-downtime migrations on large tables: expand-contract pattern (add column, dual-write, backfill, switch reads, drop old column). We use separate migration pipelines for schema changes vs data migrations, and always test migrations against production-size data in staging before applying to production.

Question 4

Can .NET applications run on Linux and in containers?

Accepted Answer

Yes — .NET 8 is fully cross-platform. Our .NET apps run on Linux in Docker containers as a standard deployment pattern. We build multi-stage Docker images (SDK for build, runtime for production) resulting in images under 200MB. For Kubernetes, we deploy with Helm charts, configure health checks, and use Dapr sidecars for service communication. .NET on Linux with Docker is our default deployment pattern for new projects.

Question 5

What is Blazor and when should I use it?

Accepted Answer

Blazor lets you build interactive web UIs using C# instead of JavaScript. Blazor Server runs UI logic on the server with a real-time SignalR connection — ideal for internal enterprise dashboards. Blazor WebAssembly runs C# in the browser via WebAssembly — ideal for SPAs where you want full-stack C#. Choose Blazor when: your team is C#-heavy, you want to share validation models between frontend and backend, or you're building internal tools. For public-facing consumer apps, React/Vue/Angular still have larger ecosystems.
