Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

.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

ESLint

  • Slow performance on large codebases compared to newer tools like Oxlint and Biome
  • Complexity in configuration from scratch, particularly for TypeScript support
  • Limited built-in TypeScript support, requiring separate parsers and coordination with new TypeScript features
