MVC 5プロジェクトにニュースレター機能を追加して、購読済みのすべてのユーザーに構築済みのメールを送信しました。
私は、public async Task<NewsletterLogResult> SendNewsletters(int? id = null, ControllerContext ControllerContext = null)を持つクラスがpublic async Task<ActionResult>SendMail(int id)
SendNewslettersがViewrenderer実装アクションから呼び出されるこれはMVCに完璧に働いているこのcBody = ViewRenderer.RenderPartialView(ViewRenderer.TemplatePath + "Newsletters/" + record.Newsletter_Template + "Body.cshtml", record, ControllerContext);.NETコンソールアプリケーションでMVC ViewRendererを実装

ような何かをしました。
Webアプリケーションから送信するニュースレターを実行するのは良い方法ではありません。この機能をWindowsサービスに実装したいと考えています。私はそれをテストすることを容易にするためコンソールアプリケーション、ここからSendNewslettersを呼び出す。 Consolappでは、WIndowsServiceと同様に、HttpContextを持っていないので、偽のHttpContextを作成することができます。MVCルーティングにアクセスすることができます（私のカミソリビューはルーティングヘルパーを実装しています、url.action）。
