.NET
- .NET 8 and .NET 9 both reach end of support on 10 November 2026, per dotnet.microsoft.com/en-us/platform/support/policy (Aug 2026), forcing an upgrade to .NET 10 by that date
- Standard Term Support releases get only 2 years of patches versus 3 years for Long Term Support releases, per Microsoft's own support policy page, so teams on an STS release face a shorter upgrade cycle
Astro
- Limited to static site generation and server-side rendering; real-time applications requiring constant client-server communication are unsuitable
- Smaller ecosystem compared to Next.js; fewer third-party component libraries and integrations readily available
- Build time increases with large content volumes (1,000+ pages); incremental builds not yet as optimised as Gatsby or Next.js
- API routes and serverless functions are less mature than Next.js; complex backend integrations require additional tooling
