Modern .NET Development

I’ve worked with .NET since the first version, and C# is the language I think in.

Lately that means .NET 9 and 10, Aspire and Orleans. I've followed .NET from the first Framework versions through .NET Core to .NET 10, so I know both the new patterns and the older code most teams still live with.

Two examples:

Betsson — Levels application

When we built the Levels application, I introduced .NET Aspire from the start for service composition, observability and local orchestration.

• Integration tests ran against Aspire's orchestrated environment, which was simpler to maintain than an equivalent Docker Compose setup
• New and rotating team members got up to speed faster thanks to a predictable structure
• Local and cloud environments behaved the same

Plejmo (Film2Home)

The platform had a traditional n-tier architecture that struggled under load. I moved it to asynchronous processing with Azure Service Bus and CQRS, separating reads from writes.

• Better performance under load
• Clearer separation of responsibilities
• Easier to change
