C# 无法加载文件或程序集'；Microsoft.SharePoint.Library'；我'；我从来没有加过

我一直在开发一个与SharePoint Online实例连接的.NET Web应用程序。一切都很顺利，直到我突然发现以下错误

Could not load file or assembly 'Microsoft.SharePoint.Library, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c' or one of its dependencies. The system cannot find the file specified.

这是我从未添加到项目中的文件或程序集。我仅通过NUGET添加了以下SharePoint软件包

• JohnHolliday.Caml.Net.SharePoint
• SharePoint.Client
• SharePoint.Client.Runtime
• SharePoint.Client.Search

任何帮助都将不胜感激

更新

已安装SharePoint Server 2013客户端组件SDK，其中包括以下内容

Microsoft.Office.Client.Education.dll
Microsoft.Office.Client.Policy.dll
Microsoft.Office.Client.TranslationServices.dll
Microsoft.SharePoint.Client.dll
Microsoft.SharePoint.Client.DocumentManagement.dll
Microsoft.SharePoint.Client.Publishing.dll
Microsoft.SharePoint.Client.Runtime.dll
Microsoft.SharePoint.Client.Search.Applications.dll
Microsoft.SharePoint.Client.Search.dll
Microsoft.SharePoint.Client.Taxonomy.dll
Microsoft.SharePoint.Client.UserProfiles.dll
Microsoft.SharePoint.Client.WorkflowServices.dll

很遗憾，没有Microsoft.SharePoint.Library

更新

终于解决了这个问题。项目的bin文件夹中有一个SharePoint.dll，一旦删除，项目就可以正常运行。

您添加的一些库，例如

SharePoint.Client

依赖于

Microsoft.SharePoint.Library

安装Sharepoint客户端组件应删除该错误。从

Good shout@Nino下载。已下载并安装SharePoint客户端组件。遗憾的是，错误仍在显示。@SeanDooley签入程序集（只需导航到c:\windows\assembly）如果您有这些库（以及正确的版本），则无法在c:\windows\assembly中找到Microsoft.SharePoint.Library
