StructureMap 4.0 came out earlier this month, thanks to the continuing work of Jeremy Miller. It’s a Big Deal since it supports .NET Core and ASP.NET 5 (among other things), but unfortunately a few things moved around, and Heroic.Web.IoC was broken (your StructureMap-related code was probably broken, too). Fortunately, the fixes are easy, and Heroic.Web.IoC is now compatible with StructureMap 4.0! You can grab it off NuGet at your leisure.
Oh, “What’s Heroic.Web.IoC?” you ask? More on that in a future post!
