Для тех, кому нужен ответ Брайана Чанса, портированный на VB.NET:
Imports System
Imports System.Web
Imports Elmah
Namespace System
Public NotInheritable Class ElmahExtension
Private Sub New()
End Sub
<System.Runtime.CompilerServices.Extension> _
Public Shared Sub LogToElmah(ex As Exception)
If HttpContext.Current IsNot Nothing Then
ErrorSignal.FromCurrentContext().Raise(ex)
Else
If httpApplication Is Nothing Then
InitNoContext()
End If
ErrorSignal.[Get](httpApplication).Raise(ex)
End If
End Sub
Private Shared httpApplication As HttpApplication = Nothing
Private Shared errorFilter As New ErrorFilterConsole()
Public Shared ErrorEmail As New ErrorMailModule()
Public Shared ErrorLog As New ErrorLogModule()
Public Shared ErrorTweet As New ErrorTweetModule()
Private Shared Sub InitNoContext()
httpApplication = New HttpApplication()
errorFilter.Init(httpApplication)
TryCast(ErrorEmail, IHttpModule).Init(httpApplication)
errorFilter.HookFiltering(ErrorEmail)
TryCast(ErrorLog, IHttpModule).Init(httpApplication)
errorFilter.HookFiltering(ErrorLog)
TryCast(ErrorTweet, IHttpModule).Init(httpApplication)
errorFilter.HookFiltering(ErrorTweet)
End Sub
Private Class ErrorFilterConsole
Inherits Elmah.ErrorFilterModule
Public Sub HookFiltering([module] As Elmah.IExceptionFiltering)
AddHandler [module].Filtering, New Elmah.ExceptionFilterEventHandler(AddressOf MyBase.OnErrorModuleFiltering)
End Sub
End Class
End Class
End Namespace
Однако для регистрации ошибок в базе данных этого будет достаточно:
If System.Web.HttpContext.Current Is Nothing Then
Dim req As System.Web.HttpRequest = New System.Web.HttpRequest(String.Empty, "https://www.domain.tld", Nothing)
Dim res As System.Web.HttpResponse = New System.Web.HttpResponse(Nothing)
System.Web.HttpContext.Current = New System.Web.HttpContext(req, res)
'Dim request As System.Web.Hosting.SimpleWorkerRequest = New System.Web.Hosting.SimpleWorkerRequest("/blah", "c:\inetpub\wwwroot\blah", "blah.html", Nothing, New System.IO.StringWriter())
'System.Web.HttpContext.Current = New System.Web.HttpContext(request)
System.Web.HttpContext.Current.ApplicationInstance = New System.Web.HttpApplication()
Dim ErrorLog As New Elmah.ErrorLogModule()
TryCast(ErrorLog, System.Web.IHttpModule).Init(System.Web.HttpContext.Current.ApplicationInstance)
End If
Как полное решение:
Public parent As Elmah.ServiceProviderQueryHandler = Nothing

А
Elmah.ErrorSignal.FromCurrentContext().Raise(New NotImplementedException("Test"))
будет работать, если он вызывается после Initialize ()
