Versioning And Upgrades
Primary docs:
- https://learn.microsoft.com/aspnet/core/release-notes/
- https://learn.microsoft.com/aspnet/core/release-notes/aspnetcore-10.0
- https://learn.microsoft.com/aspnet/core/release-notes/aspnetcore-9.0
- https://github.com/dotnet/AspNetCore.Docs/tree/main/aspnetcore/breaking-changes
Versioning Default
- For new production apps in March 2026, prefer
net10.0 - For existing apps, match the repository's target framework unless the task is explicitly an upgrade
- Before using a new API, confirm it exists in the target framework
Upgrade Workflow
- Identify the current target framework and SDK
- Read the "What's new" and breaking-changes pages for each version hop
- Compile and resolve obsoletions intentionally
- Re-run integration tests and auth flows
- Re-test deployment-specific behavior such as proxies, cookies, and static assets
High-Value Breaking-Change Checks
When moving to ASP.NET Core 10, watch for:
- cookie login redirects disabled for known API endpoints
WithOpenApideprecationWebHostBuilder,IWebHost, andWebHostobsolescence- Razor runtime compilation obsolescence
When moving to ASP.NET Core 9, watch for:
ValidateOnBuildandValidateScopesenabled in development when usingHostBuilder- middleware constructor expectations and DI validation changes
When moving to ASP.NET Core 8, watch for:
- Minimal API
IFormFileantiforgery requirements AddRateLimiter()andAddHttpLogging()requirements when corresponding middleware is used
Migration Principles
- Prefer migration to the modern hosting model when touching startup extensively
- Remove compatibility shims only after tests confirm behavior
- Avoid mixing new framework idioms with old startup architecture in a half-migrated state
- Keep one authoritative target framework in project files unless multi-targeting is deliberate
Preview Feature Rule
Do not introduce preview-only APIs or docs guidance unless the user explicitly asks for preview adoption or the repository is already on preview SDKs.
