Question

I have this code for on ASP.NET MVC website:

x.For<AccountController>().TheDefault.Is.ConstructedBy(() => new AccountController());

This code throws a warning which seems quite self explanatory but for some reason when I use the “Use” method it doesn’t seem to work. I know I am doing something wrong and would appreciate some help.

The warning is:

Warning 1 ‘StructureMap.Configuration.DSL.Expressions.CreatePluginFamilyExpression.TheDefault’ is obsolete: ‘”Prefer the Use() methods”

Thank You.

If you look at the XMLDoc for the third overload on the “Use” method, it says this:

Shorthand to say
TheDefault.IsThis(@object)

Therefore, simply do it like this:

For<AccountController>().Use(() => new AccountController());

Although i’m not sure what the point of this is (injecting a concrete when something requests a concrete), unless this is just an example, and you’re really doing something else.

Normally for the MVC Controllers, you create a ControllerFactory – i haven’t seen a need to “explicitly” inject a concrete Controller.
