ArgumentNullException Parameter name: httpContext

[alexsaare]

Locally this works as expected using IISExpress however, when deoployed to a Win2k8 R2 server (IIS 7) i'm getting an ArgumentNullException for httpContext in this method

private HttpContextBase HttpContext { get { var ctx = Container.TryGetInstance(); return ctx ?? new HttpContextWrapper(System.Web.HttpContext.Current); } }

Obviously System.Web.HttpContext is null but i'm not sure why. Any thoughts would be appreciated.

This happens for all requests. Full stack trace below (Company information sanitized)

***** UPDATE ***** This only seems to be a problem when built in release configuration.

Kind regards, Alex

OK, so, the problem was that i was replacing the default filter provider in the IoC.Initialize using this

GlobalConfiguration.Configuration.Services.GetFilterProviders()

For some reason this tries to use StructureMapDependencyScope.HttpContext which fails as System.Web.HttpContex is null when built in release mode.

The fix was to move the code to remove the default filter provider to Global.asax Application_Start()

* please close this issue *

Glad this was resolved =)

I have the same problem when a WebAPI controller is called from a client. The WebAPI controllers use constructor injection to inject a repository dependency which should be resolved by StructureMap Ioc. In the Global.asax I don't have the GlobalConfiguration.Configuration.Services.GetFilterProviders(). Interestingly, the same code runs on my another development machine. Here is my stack trace. Thanks for your help.

Do we have the fix for this? I am seeing below exception when saving content in thread which is running in background.
