I\'m getting below error. I setup it similar to asp.net mvc 4.
No parameterless constructor defined for this object. Description: An unhandled exception
StructureMap (2.6.4.1) is compatible with ASP.NET MVC 5 and you do not have to change anything after the upgrade.
The upgrade process, though, it is not as straightforward as you might think.
Here's a list of all the steps if you have to follow.
PS: I've followed Rick Anderson's tutorial after the upgrade (and he says you should do it before) but it worked, anyway.
Hope it helps.
