C# 获得；System.IO.FileLoadException“；尝试运行WorkItemTrackingHttpClient时出错
我的任务是使用asp.net从我的vsts帐户查询工作项 我使用了所有必需的库。我已经为我的vsts帐户获得了个人访问令牌，以便我可以访问我的工作项。 此外，URI是到vsts项目的链接。 运行时：C# 获得；System.IO.FileLoadException“；尝试运行WorkItemTrackingHttpClient时出错,c#,asp.net,azure-devops,workitem,C#,Asp.net,Azure Devops,Workitem,我的任务是使用asp.net从我的vsts帐户查询工作项 我使用了所有必需的库。我已经为我的vsts帐户获得了个人访问令牌，以便我可以访问我的工作项。 此外，URI是到vsts项目的链接。 运行时： 使用（workitemtrackingttpclient workitemtrackingttpclient=newworkitemtrackingttpclient（uri，_凭据）） 我得到的错误是： System.IO.FileLoadException:“无法加载文件或程序集”System.
使用（workitemtrackingttpclient workitemtrackingttpclient=newworkitemtrackingttpclient（uri，_凭据））我做错了什么吗？请检查项目中的
包文件夹下是否存在System.Net.Http.Formatting.dll
。没有任何其他版本冲突
e、 g:
无论我测试了什么，下面的示例代码对我有用，您都可以按照以下步骤进行尝试：
创建新项目
安装Nuget软件包：
为了这个项目
您可以从软件包管理器控制台安装它：
PM> Install-Package Microsoft.TeamFoundationServer.ExtendedClient -Version 15.112.1
