爲什麼我找不到需要引用的企業程序集？

Question

我正在使用Visual Studio應用程序，我想使用數據訪問應用程序塊，它是Microsoft Enterprise庫5.0的一部分。我一直在按照this guide中的步驟安裝數據訪問應用程序塊。還有就是問我引用下面的組件上this page一步：

Microsoft.Practices.EnterpriseLibrary.Data.dll

Microsoft.Practices.EnterpriseLibrary.Common.dll

Microsoft.Practices.Unity .DLL

Microsoft.Practices.ServiceLocation.dll

Microsoft.Practices.Unity.Interception.dll

問題是，當我嘗試添加它們時，我看不到它們在參考管理器中的任何位置列出。

有人可以向我解釋爲什麼我沒有看到他們/我怎麼能找到他們？

感謝

下載你需要的組件，最簡單的方法是使用NuGet安裝Data Access Application Block。

在Visual Studio中（不知道您使用的是哪個版本 - 這是針對Visual Studio 2013的）轉到菜單並選擇工具 - > NuGet程序包管理器 - >程序包管理器控制檯。應該出現控制檯。如果沒有，則選擇View-> Other Windows-> Package Manager Console。

接下來的軟件包管理器控制檯類型：

PM>安裝，包裝EnterpriseLibrary.Data -Version 5.0.505

這將安裝以前（第5版）數據訪問應用程序塊和所有的依賴關係。您應該看到在Package Manager控制檯
