I am trying to manipulate the response directly to provide a file to the user by changing the headers and writing the file to the outputstream.
the Response.Headers.Add throws the exception "This operation requires IIS integrated pipeline mode."
I am using VWD 2005 but previously had VS2008 beta 2 installed which has a known issue of breaking (see http://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx?FeedbackID=297517
my problem is that I have uninstalled .net 3/3.5, VS2008 and reinstalled both .net 2.0 and VWD yet the problem still exists.
Anyone managed to un-break this?
