vb.net調試器跳過調試線

今天早些時候，我問了這個問題debugger in vb.net skips line，但我剛剛發現了一些關於我正在開發的項目的奇怪的東西（或者對vb.net來說可能是正常的）。 我正在編輯vb文件，添加一些方法。 調試原始文件工作正常，我可以進入代碼並通過每行，逐行，沒有任何問題。 現在，當我加了一些方法調試工作確實很奇怪，檢查這兩個截圖：vb.net調試器跳過調試線

  1. 網站未啓動 - >在地方所有斷點：http://gyazo.com/1077b7efbdb2b37174d5960cdff0bda5.png?1348160907

  2. 網站開始 - >斷點在第2行缺少：http://gyazo.com/3051303d6eb27af9ea13bd6e72b81a83.png?1348161507

而且，當我加入了方法的文件，現在調試不走一行行，但在一號線的示例步驟，然後當我點擊f10，它進一步下面20行，它不會到代碼中的下一行。 我第一次編輯vb.net代碼，我一直在使用c＃，並且我不知道編輯文件後是否需要修改某些內容，以便調試器能正常工作。

原始代碼：

如果您使用ASP.net開發服務器託管，我發現即使Visual Studio已停止，該進程仍在執行代碼時發生了這種情況。當您開始一個新的調試會話時，它會嘗試關注兩個會話。我認爲這可能發生在您點擊停止按鈕而不是關閉瀏覽器窗口並且存在長時間運行或異步進程時。

嘗試右鍵單擊任務欄中的ASP.net開發服務器圖標並選擇停止，然後開始調試。
