is related to SPRNET-1443 Support for ASP.NET MVC3 Resolved


Changes in the lifecycle of the the scope of the HttpContext.Request object under IIS7 in integrated pipeline mode result in "Request is not available in this context" exceptions when the Request is depended upon in Application_Start(). This has broken WebContextHandler in this use-case.

See http://mvolo.com/blogs/serverside/archive/2007/11/10/Integrated-mode-Request-is-not-available-in-this-context-in-Application_5F00_Start.aspx for info on a possible pattern employed to address the issue of attempting to access the HttpContext.Request object before its been properly created under IIS7 + integrated pipeline mode. This pattern was successfully employed to resolve a similar issue for the MvcContextHandler under SPRNET-1443.

do you have a stacktrace? as mentioned there is a fix in place, on some occasions it seems though that this fix doesnt catch a particular scenario. I need to know what exactly this scenario is

After further investigation, it turns out this issue was only appearing in mixed WebForms and MVC3 applications and was actually also fixed by the subsequent work in SPRNET-1443 to address the same error condition under MVC3. In MVC3, the container init would (by default) happen too soon in the ASP.NET application lifecycle where the REQUEST object was not yet in scope. Fixing this under MVC3 as in SPRNET-1443 has alredy 'fixed' this for the mixed-use application case as well.

Hi Erich,
In my project, when using the container (ContextRegistry.GetContext()) in Application_Start, I still encounter this dreaded exception. Could you please give me some information about this particular issue? If you need a project that shows the exception, I can send you one.

If you have a project that demonstrates this issue (reliably!) can you please zip it up and attach it to this issue? Thanks~!

There is a new report that this issue still exists, so re-opening it to track it (again).
