ASP.NET Core 2.3 support ends April 13

Microsoft says ASP.NET Core 2.3 will reach end of support on April 13, 2027, after which it gets no more security patches, bug fixes, or technical support. The company is steering teams toward supported .NET releases and GitHub Copilot modernization to plan and execute the migration.

// ANALYSIS

This is less a launch than a hard modernization deadline, and Microsoft is being blunt about the tradeoff: stay put and own the risk, or upgrade and reap the gains from modern .NET. The date was also updated from April 7 to April 13, 2027 to align with Microsoft servicing cycles.

–ASP.NET Core 2.3 is now legacy enough that Microsoft no longer recommends it as a migration strategy.
–After support ends, the included Entity Framework 2.3 packages lose support on the same date.
–Teams that stay on it give up security fixes and technical support, which turns maintenance debt into real exposure.
–Microsoft is explicitly pointing developers to currently supported .NET versions, including .NET 10 LTS.
–The Copilot modernization angle matters: upgrades like this are increasingly about inventorying code, planning refactors, and automating migration work.

Global LLM capabilities rapidly converge

A discussion on X highlights the noticeable convergence in capabilities among top-tier Large Language Models, noting that both Western and Chinese models—such as MiniMax's multimodal offerings—are exhibiting highly comparable performance, distinguished primarily by their unique quirks and specialized strengths. As foundation models across developers reach a parity plateau, industry observers are questioning if we have entered a phase of diminishing returns for current architectures and when the next definitive leap forward in artificial intelligence will emerge.
