我正在开发Visual Studio应用程序，我想使用数据访问应用程序块，它是Microsoft Enterprise库5.0的一部分。我一直在按照this guide中的步骤安装数据访问应用程序块。 this page上有一个步骤要求我引用以下程序集：
Microsoft.Practices.EnterpriseLibrary.Data.dll
Microsoft.Practices.EnterpriseLibrary.Common.dll
Microsoft.Practices.Unity.dll
Microsoft.Practices.ServiceLocation.dll
Microsoft.Practices.Unity.Interception.dll
问题在于，当我尝试添加它们时，我看不到它们在参考管理器中的任何位置列出。
有人可以向我解释为什么我看不到它们/我怎么能找到它们？

下载所需程序集的最简单方法是使用NuGet安装Data Access Application Block。
在Visual Studio中（不确定您使用的是哪个版本 - 这适用于Visual Studio 2013），转到“菜单”并选择“工具” - >“NuGet包管理器” - >“包管理器控制台”。控制台应该出现。如果没有，则选择View-＆gt; Other Windows-＆gt; Package Manager Console。
接下来在Package Manager控制台中输入：
PM＆GT; Install-Package EnterpriseLibrary.Data -Version 5.0.505
这将安装以前的（版本5）数据访问应用程序块及其所有依赖项。您应该在程序包管理器控制台中看到以下内容

另一种方式是download Enterprise Library，然后从安装位置引用各个程序集。
