.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

  • SolidJS less familiar to developers with React experience
  • Community documentation not as extensive as larger frameworks
  • Limited third-party UI component libraries compared to React ecosystem
