Episode notes
Fundamentals Remain A Core Focus
- ASP.NET Core invests in fundamentals: performance, security, observability and OpenTelemetry integration.
- .NET 10 added Blazor-specific metrics and CPU/memory diagnostics for WebAssembly to improve troubleshooting.
Choose The Modern Stack For New Features
- Prefer the modern ASP.NET Core stack (minimal APIs and Blazor) for new investments and features.
- MVC and Razor Pages remain supported but won't receive the same level of new app-model innovation.
Silverlight Fears Persist But Runtime Reuses Exist
- Developers still asked if Blazor will become the next Silverlight long after Silverlight's end of life.
- Daniel noted OpenSilver uses the same WebAssembly runtime to run Silverlight-like apps in browsers today.
