Problem in Consuming Web Service

Hello

When I write code using WebMatrix as follows

<%@ Page Language="VB" %>
<%@ import Namespace="TestServiceClass" %>
<script runat="server">

Sub Button1_Click(sender As Object, e As EventArgs)

Dim myService as New SecurityWebService()

txtPrice.text = myservice.GetSecurityInfo()

End Sub

Following error occurs :

Compiler Error Message: BC30002: Type 'SecurityWebService' is not defined.


AND When I write code using WebMatrix as follows

<%@ Page Language="VB" %>
<script runat="server">

Imports TestServiceClass

Sub Button1_Click(sender As Object, e As EventArgs)

Dim myService as New SecurityWebService()

txtPrice.text = myservice.GetSecurityInfo()

End Sub

Compiler Error Message: BC30465: 'Imports' statements must precede any declarations.

I have 2 files as follows

1. TestServiceClass.vb in current "work directory"
2. TestServiceClass.dll in "work directory\bin"

Please suggest some solution.

Note : I do not have Microsoft Visual Studio .NET
