Upgrade to .NET 9 - Githubissues

tjementum commented 2 days ago

Summary & Motivation

Upgrade the project from .NET 8 to .NET 9, bringing improved features and simplifying workflows. All .NET projects and the global global.json have been updated to target .NET 9. NuGet packages have also been upgraded to their .NET 9-compatible versions, except for Entity Framework, which remains on the older version due to test failures caused by multiple service registrations.

The Docker image has been updated to use mcr.microsoft.com/dotnet/aspnet:9.0-alpine, and GitHub Actions have been upgraded to use .NET 9. Additionally, the Aspire workload installation step has been removed from GitHub Actions, as it is no longer needed.

The SslCertificateManager has been refactored and simplified with .NET 9’s new cross-platform X509CertificateLoader.LoadPkcs12FromFile method, replacing the now-deprecated new X509Certificate2(certificateLocation, password). This change makes creating self-signed developer certificates for localhost significantly simpler and ensures compatibility across Mac and Windows platforms.
