PlatformNotSupportedException when accessing HttpReponse.Headers

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.httpresp onse.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

Re: PlatformNotSupportedException when accessing HttpReponse.Headers

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,

Re: PlatformNotSupportedException when accessing HttpReponse.Headers

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.
