無法加載文件或程序集“ Microsoft.Data.Service”或其依賴項之一。 該系統找不到指定的文件

Question

我剛切換計算機，但我的項目之一無法正常運行，並在標題中引發了錯誤。 （您可能還會在下面找到完整的錯誤消息）顯然是在尋找錯誤的位置，但是目前我不確定要更改什么。 請指教。

請記住一些事實

• 我沒有更改源代碼中的任何代碼行
• 在由VSTS部署的新生產服務器上運行正常
• 我正在使用IISExpress來運行它
• 我正在使用Visual Studio 2015 v14.0.25431.01更新3
• 與我的上一台計算機的主要區別之一是該計算機上裝有Visual Studio 2017 RC 。 （我不認為這是什么原因，但誰知道呢）

程序和特點

存在以下申請

• WCF數據服務5.6.3工具

Bin目錄

存在以下文件

• Microsoft.Data.Edm.dll
• Microsoft.Data.OData.dll
• Microsoft.Data.Services.Client.dll
• Microsoft.Data.Services.dll

我不得不重新打開該項目，意識到程序集不在加載的模塊中 。 我檢查了為bin\\{Configuration}設置的輸出目錄，將其更改為bin解決了該問題。
