Description: Overview This PR updates the entire solution from .NET 6.0 (which is now out of support) to .NET 9.0, the latest stable version. All NuGet packages have been updated to their latest compatible versions. Motivation .NET 6.0 reached end of support and is no longer receiving security updates. The build system was showing warnings: warning NETSDK1138: The target framework 'net6.0' is out of support and will not receive security updates in the future. Additionally, many packages were using versions from 2022 and needed to be brought up to date. Changes Made Target Framework Updates All four projects have been updated: DIDemo (main web application) DIDemoServices (service library) DIDemo.Tests (unit tests) DIDemo.Services.Tests (service tests) Updated from net6.0 → net9.0 Package Updates Main Application (DIDemo): Entity Framework Core packages: 6.0.7 → 9.0.1 Microsoft.Extensions packages: 6.0.0 → 9.0.1 ASP.NET Core packages: 6.0.7 → 9.0.1 Services Library (DIDemoServices): Configuration abstractions: 6.0.0 → 9.0.1 Newtonsoft.Json: 13.0.1 → 13.0.3 Test Projects: Microsoft.NET.Test.Sdk: 17.2.0 → 17.12.0 MSTest packages: 2.2.10 → 3.7.0 Code Modernization Updated Program.cs to use the modern .NET hosting pattern: Before: public static IWebHostBuilder CreateWebHostBuilder(string[] args) => WebHost.CreateDefaultBuilder(args) .UseStartup(); After: public static IHostBuilder CreateHostBuilder(string[] args) => Host.CreateDefaultBuilder(args) .ConfigureWebHostDefaults(webBuilder => { webBuilder.UseStartup(); }); This aligns with the recommended .NET hosting model while maintaining full compatibility with the existing Startup class pattern. Verification ✅ All projects build successfully with zero warnings ✅ All unit tests pass (2/2 test projects) ✅ No breaking changes to existing functionality ✅ Minimal code changes - only version updates and hosting modernization Benefits Security: Access to the latest security patches and updates Performance: .NET 9.0 includes numerous performance improvements Support: Active support from Microsoft through November 2026 Modern Features: Access to the latest C# language features and runtime improvements Migration Notes This update is fully backward compatible with the existing codebase. No changes are required to existing services, controllers, or business logic. The Dependency Injection patterns demonstrated in this repository continue to work identically in .NET 9.0. Original prompt This section details on the original issue you should resolve Update Dependencies and .NET Update all packages and dependencies. Take .NET to the latest version.
