Differences from .net 4.5/MVC 5

Core/net5/net6 has changed design several times

• Project
  • Revised (minimal) version of csproj, including PackageReference(nuget) Pre 2016 it was xproj and project.json
  • References are now Nuget packages (dependencies in project.json csproj)
  • No global.asax
    • Core/net5: program.cs and startup.cs
    • net6: program.cs
  • It is multi-platform (linux servers/containers).
• Asp
  • No Asp lifecycle events- it has OWIN type middleware
  • You can't just deploy the asp project folder. The web root is now the wwwroot folder. You need to Publish (to Release/publish folder) which puts the web.config/exe/dlls top and copies wwwroot below.
  • No bundling - use LigerShark.WebOptimizer.Core or gulp instead
  • Front-end resources (jquery etc) are not nuget any more.
  • Dependency injection is pervasive (not service-locator as before)
  • MVC and WebApi are the same now, not parallel frameworks with misleading similarities (2 different AuthorizeAttributes)
  • Less IIS. For core 2 you used kestrel to IIS, but we're back in IIS now.
  • A minimal, static web.config. All configuration settings are via the configuration system- environment variables, json files..
