• •ASP.NET Core 2.3 support ends on April 7, 2027, with no further updates.
• •Users are advised to upgrade to modern ASP.NET on .NET 10.
• •The versioning strategy has led to confusion and compatibility issues for developers.

Microsoft has announced that ASP.NET Core 2.3, the only supported version on .NET Framework, will reach its end-of-support date on April 7, 2027. After this date, no security patches, bug fixes, or technical support will be provided for this version. Users are encouraged to upgrade to modern ASP.NET on .NET 10. The .NET Framework remains maintained but focuses on stability rather than new features. ASP.NET Core 2.3 was released in early 2025 as a re-release of version 2.1 to address compatibility issues that arose when version 2.2 went out of support. This versioning strategy has caused confusion among developers, particularly those unable to migrate from older Windows Servers. The decision to end support is attributed to the high costs of maintenance and compliance. Statistics indicate that versions 2.2 and 2.3 are still frequently installed, impacting many organizations reliant on these frameworks.
