Create .NET (C#) Web API Backstage Template

[NgocAnhDo26]

Background

We need a template for C# developers to quickly scaffold a .NET Web API that is ready to be deployed to our Kubernetes cluster via Tekton and ArgoCD.

Specific Steps

• Create a basic ASP.NET Core Web API project in apps/portal/examples/dotnet-template/content/source.
• Add a Dockerfile customized for .NET (multi-stage build).
• Add a docker-compose file so dev can start local environment easily for development.
• Configure appsettings.json to read Database connection variables dynamically from environment variables (DB_HOST, DB_USER, DB_PASSWORD, DB_NAME).
• Create template.yaml (copying the structure from existing Node.js templates) and register it in app-config.yaml.

Expected Output

A working Backstage software template where a user can input a name and get a Git repo with a compiled .NET API that automatically parses injected Database credentials.
