我在startup.cs上添加装配线后才出现此错误

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using Microsoft.Owin;
using Owin;

[assembly: OwinStartupAttribute(typeof(InnovationInABoxWebApi.App_Start.Startup))]
namespace InnovationInABoxWebApi.App_Start
{
    public partial class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            ConfigureAuth(app);
        }
    }
}

这是package.json

尝试通过

安装此软件包 
Nuget Install-Package Microsoft.IdentityModel.Protocols.WsFederation -Version 5.2.0.0

答案 1 :(得分：1)

  1. 验证Web.Config是否有新旧版本的dependentAssembly“ Microsoft.IdentityModel.Protocols.WsFederation”。 Visual Studio默认模板最后在版本号后附加了一个额外的“ 0”。 例如实际值：oldVersion =“ 0.0.0.0-5.2.1.0.0” newVersion =“ 5.2.1.0.0” 将值替换为：oldVersion =“ 0.0.0.0-5.2.1.0” newVersion =“ 5.2.1.0”

  2. 打开程序包管理器控制台并运行 安装软件包Microsoft.IdentityModel.Protocols.WsFederation -5.2.1.0版

这一步解决了我的问题
