无法加载我从未添加过的文件或程序集“Microsoft.SharePoint.Library”

Posted 2021-03-26

我一直在开发一个与SharePoint Online实例连接的.NET Web应用程序。一切顺利，直到我突然开始出现以下错误

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。我只通过NUGET添加了以下SharePoint包

• JohnHolliday.Caml.Net.SharePoint
• SharePoint.Client
• SharePoint.Client.Runtime
• SharePoint.client.search

任何帮助将不胜感激。

UPDATE

已安装的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

不幸的是，没有Microsoft.SharePoint.Library。

UPDATE

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，该项目就能正常运行。

答案

您添加的某些库（例如SharePoint.Client）依赖于Microsoft.SharePoint.Library

安装Sharepoint客户端组件应该删除该错误。从here下载
