Migrate from ASP.NET MVC 5 to ASP.NET Core 7 Web API

Summary

This PR migrates the application from .NET Framework 4.8 / ASP.NET MVC 5 to ASP.NET Core 7 Web API. The AngularJS frontend remains unchanged and is now served as static files from the wwwroot directory.

Key Changes:

• Project File: Converted to SDK-style .csproj targeting net7.0
• Application Entry: Created Program.cs with minimal API setup, static file serving, and CORS middleware
• Static Files: Moved all frontend assets (Content/, WebApp/) to wwwroot/ directory
• HTML Bootstrap: Converted Views/Landing/Index.cshtml (Razor) to wwwroot/index.html (static HTML)
• Dependencies: Copied jQuery and Angular from node_modules to wwwroot/lib/
• Removed: All .NET Framework-specific files (Global.asax, Web.config, BundleConfig, RouteConfig, Controllers, Views, etc.)

What Stayed the Same:

• AngularJS application structure (wwwroot/WebApp/app.js, components, directives) - completely unchanged
• Application port: http://localhost:51267
• npm dependencies and package.json

Review & Testing Checklist for Human

⚠️ Important: I was unable to test this locally as .NET SDK 7.0 is not installed in the development environment. All verification must be done by the reviewer.

• Build Verification: Run dotnet build and confirm it succeeds without errors
• Run Application: Execute dotnet run and verify the app starts on http://localhost:51267
• Visual Verification: Open the app in a browser and confirm:
  • Page loads with title "XLTS for AngularJS with ASP.NET Core 7"
  • test-component displays "AngularJS Version: 1.8.3"
  • test-directive displays "jQuery Version: 3.6.3"
  • No console errors in browser developer tools
• Static File Paths: Verify all CSS and JS files load correctly (check Network tab in browser dev tools)
• Production Considerations: Evaluate whether to add bundling/minification for production deployments (the old app used ASP.NET bundling, which was removed for simplicity)

Notes

• The CORS policy is configured for http://localhost:51267, though it may not be necessary since the frontend is served from the same origin
• The AngularJS directive uses templateUrl: 'WebApp/Directives/test.directive.html' which should resolve correctly from the new wwwroot structure, but verify it loads
• E2E tests in the e2e/ directory may need updates if they expect specific server behavior
