DotNetOpen​Auth in IIS7; request not available

问题:

Recently the company I work for has begun implementing OAuth in one of their web services. However, yesterday I came across a rather unusual problem.

When debugging the application on a remote computer, I receive the following error: "System.Web.HttpException: Request is not available in this context". Now, when I first encountered this problem I found out that this usually has to do with the fact that I can't use the HttpContext object in the Application_Start method of Global.cs, so I removed all references to that object from the method (as described here; http://mvolo.com/blogs/serverside/archive/2007/11/10/Integrated-mode-Request-is-not-available-in-this-context-in-Application_5F00_Start.aspx)

However, the problem persists when running the code on the remote computer (which is where IIS7 configuration Manager is installed). What's more, the stack trace refers to a path named "C:\rws\lib \dnoatst.net4\Samples\ZuydOAuthServiceProvider\Code\Global.cs", which makes no sense to me because the actual files are located on the D:\ disk. I cannot find a reference to that path anywhere in the source code.

Does anyone have any experience with this particular issue? Any help would be greatly appreciated!

After some testing, it seems that there is a solution to this issue, albeit not a perfect one. Setting the Application Pool's managed pipeline mode to "Classic" seems to do the trick, however, I am somewhat worried that this will cause problems at a later stage.

If anyone knows how to solve the problem described in my initial post without using Classic managed pipeline mode, I would appreciate you sharing your thoughts.
