IHttpAsyncHandl er outputting ashx directive

[=?Utf-8?B?Z2hhdXNl?=]

I'm trying to stream in image from another domain asynchronously.
My ashx looks like this:
<%@ WebHandler Language="VB" Class="Handlers .AsyncImageHand ler" Debug="true"
%>

Here is the vb:
Imports System.net
imports system.io

Namespace .Handlers

Public Class AsyncImageHandl er
Implements System.Web.IHtt pAsyncHandler

Private _context As HttpContext
Private _webreq As HttpWebRequest

Sub ProcessRequest( ByVal context As HttpContext) _
Implements System.Web.IHtt pHandler.Proces sRequest
Throw New InvalidOperatio nException()
End Sub
Function BeginProcessReq uest(ByVal context As HttpContext, ByVal cb
As AsyncCallback, ByVal extraData As Object) As IAsyncResult _
Implements System.Web.IHtt pAsyncHandler.B eginProcessRequ est

' Save a reference to the HttpContext
_context = System.Web.Http Context.Current

_webreq =
DirectCast(WebR equest.Create(" http://www.nws.noaa.go v/weather/images/fcicons/shra20.jpg"), HttpWebRequest)

Return _webreq.BeginGe tResponse(cb, extraData)
End Function

Sub EndProcessReque st(ByVal result As IAsyncResult) _
Implements System.Web.IHtt pAsyncHandler.E ndProcessReques t
Try
Dim response As HttpWebResponse =
CType(_webreq.E ndGetResponse(r esult), HttpWebResponse )
Dim Image As Byte()

Image =
getImageByteArr ay(System.Drawi ng.Image.FromSt ream(response.G etResponseStrea m()))
_context.Respon se.ContentType = "image/jpeg"
_context.Respon se.AddHeader("V ary", "User-Agent")

_context.Respon se.OutputStream .Write(Image, 78, Image.Length
- 78)
Finally

End Try
End Sub

ReadOnly Property IsReusable() As Boolean Implements
IHttpHandler.Is Reusable
Get
Return False
End Get
End Property

Private Function getImageByteArr ay(ByVal image As
System.Drawing. Image) As Byte()
Dim ms As New MemoryStream()
image.Save(ms, System.Drawing. Imaging.ImageFo rmat.Jpeg)
Return ms.ToArray()
End Function
End Class
End Namespace
The baffiling response content (in text format) looks like this:

<%@ WebHandler Language="VB" Class="Handlers .AsyncImageHand ler" Debug="true"
%>
����

What could I be doing that is sending the handler directive in the response?

response?

Sounds like ASP.NET isn't correctly registered for the application.

..ashx should mapped to
C:\WINDOWS\Micr osoft.NET\Frame work\vXXXXX\asp net_isapi.dll

as a script engine.

Try running aspnet_regiis again.
