.NET 10 → .NET 11 Migration
Migrate a .NET 10 project or solution to .NET 11, systematically resolving all breaking changes. The outcome is a project targeting net11.0 that builds cleanly, passes tests, and accounts for every behavioral, source-incompatible, and binary-incompatible change introduced in .NET 11.
Note: .NET 11 is currently in preview. This skill covers breaking changes documented through Preview 1. It will be updated as additional previews ship.
When to Use
- Upgrading
TargetFrameworkfromnet10.0tonet11.0 - Resolving build errors or new warnings after updating the .NET 11 SDK
- Adapting to behavioral changes in .NET 11 runtime, ASP.NET Core 11, or EF Core 11
- Updating CI/CD pipelines, Dockerfiles, or deployment scripts for .NET 11
- Fixing C# 15 compiler breaking changes after SDK upgrade
When Not to Use
- The project already targets
net11.0and builds cleanly — migration is done - Upgrading from .NET 9 or earlier — address the .NET 9→10 breaking changes first
- Migrating from .NET Framework — that is a separate, larger effort
