Modernizing Legacy .NET Apps with Docker
summary
Demos show a legacy ASP.NET WebForms app packaged with Dockerfiles for Windows, a SQL Server container, and an image2docker extraction; synchronous DB writes become an event published to NATS and processed by a small .NET console handler, which removes the DB bottleneck and scales. Front end moves into Umbraco behind an nginx proxy, health checks and a multi-service docker-compose CI pipeline build from an MSBuild image — all run successfully in the demo.
