I have added the following in my Global class:

    Private Shared Sub InjectTraceExtensionToConfig()
        Dim assBase As Assembly
        Dim webServiceConfig As Type
        Dim currentProp As Object
        Dim propInfo As PropertyInfo
        Dim value As Object()
        Dim myType As Type
        Dim objArray As Object()
        Dim myObj As Object
        Dim myField As FieldInfo

        Try
            assBase = GetType(System.Web.Services.Protocols.SoapExtensionAttribute).Assembly
            webServiceConfig = assBase.[GetType]("System.Web.Services.Configuration.WebServicesCon figuration")

            If webServiceConfig Is Nothing Then
                Throw New Exception("Error ...")
            End If

            currentProp = webServiceConfig.GetProperty("Current").GetValue(Nothing, Nothing)
            propInfo = webServiceConfig.GetProperty("SoapExtensionTypes")
            value = DirectCast(propInfo.GetValue(currentProp, Nothing), Object())
            myType = value.[GetType]().GetElementType()
            objArray = DirectCast(Array.CreateInstance(myType, CInt(value.Length) + 1), Object())
            Array.Copy(value, objArray, CInt(value.Length))

            myObj = Activator.CreateInstance(myType)
            myField = myType.GetField("Type")
            myField.SetValue(myObj, GetType(TraceExtension))
            objArray(CInt(objArray.Length) - 1) = myObj
            propInfo.SetValue(currentProp, objArray, Nothing)
        Catch ex As Exception
        End Try
    End Sub

The Global class is called from Global.asax:

< @ Application Language="VB" Inherits="Framework.GlobalBase"%>

But, as is, it will not do anything. Something has to trigger this method. This is where I am not sure about the proper way to establish a trigger here. When this is in the web.config. the trigger is done by .NET. But, in the code, there is a missing link here.

The reason I want to put this in the code is to have the control over it. Everything that most of the people usually put in Global.asax, I put it in my Global class. Then, from Global.asax, the only thing I have to put is the one line you see above. By that, I do not have to worry about setting up web.config wherever I need a Web site or Web service application. I control everything from the framework and that makes it easier to migrate to another development environment when time comes. This Global.asax is to proprietary to .NET.
