Web API 2: HttpServer in-memory server and App/Web.config?

Question

For unit testing, I'm running an in-memory server using the System.Web.Http.HttpServer class. It chokes when attempting to instantiate Enterprise Library objects, because Enterprise Library (v5.0.414.0) is configured in the XML configuration file App.config, which isn't being read.

Is it possible to read in the .config file, or am I forced to start a local server (e.g. WcfSvcHost.exe)?

UPDATE:

I'm able to load the configuration thusly (from How to OpenWebConfiguration with physical path?):

var wcfm = new System.Web.Configuration.WebConfigurationFileMap();
var vdm = new System.Web.Configuration.VirtualDirectoryMapping( @"C:\MyPath\", true, "App.config" );
wcfm.VirtualDirectories.Add( "/", vdm );
var cfg = System.Web.Configuration.WebConfigurationManager.OpenMappedWebConfiguration( wcfm, "/" );

However, I don't know of any straightforward way to pass that data to the HttpServer object (cfg is a Configuration type, apparently of no relation to the HttpConfiguration type found in HttpServer constructors).

I wanted to avoid implementing an IISExpress solution, but it looks as though I'm forced to go that route in order to support Enterprise Library 5 lameness.

Note that I found stackoverflow.com/questions/2368748/…, which works for loading the XML file, but presumably a System.Configuration.Configuration object is incompatible with the HttpServer type. I'm looking for a solution that works for the in-memory HttpServer. — MiloDC

I have Microsoft.VisualStudio.TestTools.UnitTesting tests which test components that rely on settings in the .config file. It's definitely reading the app.config. — Mick

Turns out, the in-memory HttpServer class works fine; no need for the Owin stuff. I just needed to have references to a few Enterprise Library assemblies in my unit test project as well as my Web API 2 project.

Fusion logging saved the day again. Such a great way to debug obscure library resolution errors. ( http://www.hanselman.com/blog/BackToBasicsUsingFusionLogViewerToDebugObscureLoaderErrors.aspx )
