Upgrading Yields Instant Performance Gains
- Upgrading to the latest .NET gives immediate performance and memory improvements without changing your code.
- Daniel Roth highlights .NET 10's runtime and library optimizations that reduce allocations and shrink memory footprints for existing apps.
Upgrade When You Can And Use Modernization Tools
- Do upgrade when possible because the ASP.NET team keeps a high compatibility bar and breaking changes are minimal.
- Use app modernization tooling or GitHub Copilot app modernization to scan and fix remaining breaking-change sites in large solutions.
Async Validation Is Finally Coming
- ASP.NET Core's public GitHub roadmap focuses on four themes including addressing long-standing pain points.
- Daniel calls out async validation as a decades-old top request being implemented across minimal APIs, Blazor, and core abstractions in .NET 11.
