C# This operation requires IIS integrated pipeline mode.

When trying to add Http Headers to your Response object you may get the error “This operation requires IIS integrated pipeline mode.” This is what looks like a bug in the .net framework. In order to work around this issue you should add the Http Headers to the Response using the following format.

HttpContext.Current.Response.AddHeader("ContentType", "application/x-www-form-urlencoded");
