System.IdentityModel.Tokens的命名空间下缺少X509SecurityToken

Question

我为visual studio 2012安装了“用于Microsoft .Net Framework 4.5的JSON Web令牌处理程序”的Nuget包（链接： - http://www.nuget.org/packages/System.IdentityModel.Tokens.Jwt/）。但它不包含“X509SecurityToken”的定义。导致以下方法显示错误的原因......

   private static void ValidateToken(string Token)
   {
        var tokenHandler = new JwtSecurityTokenHandler();
        var validationParameters = new TokenValidationParameters()
        {
            ValidAudience = "<some url>",
            IssuerSigningTokens = new List<X509SecurityToken>() { new X509SecurityToken(
           X509
           .LocalMachine
           .My
           .Thumbprint
           .Find("112233445566xxyy", false)
           .First()) },
            ValidIssuer = "https://my-issuer.com/trust/issuer",
            CertificateValidator = X509CertificateValidator.None,
            RequireExpirationTime = true
        };

        try
        {
            SecurityToken validatedToken;
            var principal = tokenHandler.ValidateToken(Token, validationParameters, out validatedToken);
        }
        catch (Exception e)
        {

            Console.WriteLine("{0}\n {1}", e.Message, e.StackTrace);
        }

        Console.WriteLine();
    }

如果有人能提供任何帮助甚至提示，我将不胜感激，

尝试添加对System.IdentityModel的引用。
