PlatformNotSupportedException when accessing HttpReponse.Headers

[newsgroup.poster]

I encounter the following exception when accessing
HttpResponse.Headers after having installed .net 3.5 SDK:

[PlatformNotSupportedException: This operation requires IIS integrated
pipeline mode.]
System.Web.HttpResponse.get_Headers() +3300614

My server is windows 2003 (iis6), my dev environment is winxppro
(either iis5 or vswebdevserver).

I've saw description of this exception here

http://msdn2.microsoft.com/en-us/library/system.web.httpresponse.headers.aspx#ddueExceptionsToggle

but I don't understand why it should apply because I don't use iis 7.

I'm working arround by hacking ContentType property appending required
headers, but I wonder if there is a way to fix this problem?

Thanks,

Gauthier Segay

The feature you're looking for only works with IIS 7, that's why you're
getting the PlatformNotSupportedException. If you try to run this code on
IIS 6 you'll get this exact error because it's not available. The way you're
doing this is correct for the version of IIS you have available.

Hope this helps,

I got confused because I sure have used headers with asp.net before,
but it seems I was wrong and always relied on this trick.

Thanks for your answer and clarification.
