Version 3 of the StructureMap Dependency Injection / Inversion of Control library for .NET

Home page: https://structuremap.github.io/

What’s Different and/or Improved in StructureMap 3?

Details taken from http://jeremydmiller.com/2014/03/31/structuremap-3-0-is-live/

  • The diagnostics and exception messages are much more useful
  • The registration DSL has been greatly streamlined with a hard focus on consistency throughout the API
  • The core library is now PCL compliant and targets .Net 4.0. So far SM3 has been successfully tested on WP8
  • Removed strong naming from the public packages to make the world a better place.
  • Nested container performance and functionality is vastly improved (100X performance in bigger applications!)
  • Xml configuration and the ancient attribute based configuration has been removed.
  • Interception has been completely rewritten with a much better mechanism for applying decorators (a big gripe of mine from 2.5+)
  • Resolving large object graphs is faster
  • The Profile support was completely rewritten and more effective now
  • Child containers (think client specific or feature specific containers)
  • Improvements in the usage of open generics registration for Jimmy Bogard
  • Constructor function selection and lifecycle configuration can be done per Instance (like every other IoC container in the world except for SM < 3.0)
  • Anything that touches ASP.Net HttpContext has been removed to a separate StructureMap.Web nuget.
  • Conventional registration is more powerful now that the configuration model is streamlined and actually useful as a semantic model
