ASP.NET Core 2.3 hits end of support

Microsoft says ASP.NET Core 2.3 will reach end of support on April 13, 2027, ending security patches, bug fixes, and technical support for the legacy migration-era package line. The company is steering teams toward currently supported .NET releases and GitHub Copilot modernization to map and execute the upgrade.

// ANALYSIS

This is a maintenance-life-cycle warning, not a launch, but it matters because old web stacks have a way of lingering until the security bill comes due.

–Microsoft quietly updated the date from April 7 to April 13, 2027 to match servicing cycles, so teams should plan against the newer date
–The real message is architectural: ASP.NET Core 2.3 is now considered too stale to remain a migration target
–The migration path is to modern .NET, with .NET 10 LTS called out as the preferred destination
–GitHub Copilot modernization is the notable angle here: Microsoft is pushing AI-assisted migration planning, not just docs and checklists
–The product homepage positions ASP.NET Core as fast, secure, open source, and cross-platform, which makes the upgrade argument straightforward for teams still on old Framework-era dependencies
