System.IdentityModel.Tokens.Jwt 未找到

Question

我想使用 C#（.Net Framework v 4.5）和 ASP.Net 开发 Sharepoint webhook。为此，我采用以下软件包：

</packages>

但是我在下面的第一个启动后得到class这个消息： TokenValidationParameters 中的编译器错误 CS0246 和 CS7069

Error CS7069 The reference to type "TokenValidationParameters" was supposedly declared in "System.IdentityModel.Tokens.Jwt" but could not be found.

和

Error CS0246 The type or namespace name "TokenValidationParameters" was not found (possibly missing a using directive or assembly reference).

using System;
using System.Collections.Generic;
using System.Configuration;
using System.IdentityModel;
using System.IdentityModel.Tokens.Jwt;
using Microsoft.IdentityModel;
using System.Linq; 
using Microsoft.Owin.Security;
using Microsoft.Owin.Security.ActiveDirectory;
using Owin;

namespace WebApplication
{
    public partial class Startup
    {
        public void ConfigureAuth(IAppBuilder app)
        {
            app.UseWindowsAzureActiveDirectoryBearerAuthentication(
                new WindowsAzureActiveDirectoryBearerAuthenticationOptions
                {
                    Tenant = ConfigurationManager.AppSettings["ida:Tenant"],
                    TokenValidationParameters = new TokenValidationParameters {
                         ValidAudience = ConfigurationManager.AppSettings["ida:Audience"]
                    },
                });
        }
    }
}

我做错了什么？

我在 C# 和 ASP.NET 方面没有太多经验。

Answer 1

错误 CS0246 的原因未找到类型或命名空间名称 “TokenValidationParameters”（可能缺少 using 指令或程序集引用）是 Microsoft.IdentityModel.Tokens .cs 文件中缺少程序集引用。请在 class 文件中导入以下命名空间。

using Microsoft.IdentityModel.Tokens;
