.net-core - System.PlatformNotSupportedException : 'Operation is not supported on this platform.' when upgrading ServiceStack to .netcore 2.0

Question

我们在一个尚未上线的开源项目中使用 ServiceStack(.netcore) 作为我们的 Web 服务层。我们正计划迁移到 .netcore2.0。我们于 11 月 17 日从 https://github.com/ServiceStack/ServiceStack 下载了 servicestacks 的 master 分支。用于检测。但是由于以下异常，我们被卡住了，servicestack 项目没有启动。

我们对此做了一些研究，发现 .Net Core 没有 toXmlString() 和 fromXmlString 方法。请查看 https://github.com/dotnet/core/issues/874和 https://github.com/dotnet/corefx/issues/23686 .

需要服务堆栈社区的帮助。

这是我们的 Startup.cs 中生成异常的行。

var jwtprovider = new MyJwtAuthProvider(AppSettings)
            {
                HashAlgorithm = "RS256",
                PrivateKeyXml = EbLiveSettings.PrivateKeyXml,
                PublicKeyXml = EbLiveSettings.PublicKeyXml,
                RequireSecureConnection = false,
                //EncryptPayload = true,
                CreatePayloadFilter = (payload, session) =>
                {
                    payload["sub"] = (session as CustomUserSession).UserAuthId;
                    payload["cid"] = (session as CustomUserSession).CId;
                    payload["uid"] = (session as CustomUserSession).Uid.ToString();
                    payload["wc"] = (session as CustomUserSession).WhichConsole;
                },
                ExpireTokensIn = TimeSpan.FromHours(10),
                ExpireRefreshTokensIn = TimeSpan.FromHours(12),
                PersistSession = true,
                SessionExpiry = TimeSpan.FromHours(12)
            };

私钥和公钥值从 appsettings.json 加载到 EbLiveSettings。

appsettings.json 中的行是

"JwtConfig": {
    "PublicKeyXml": "<RSAKeyValue><Modulus>ip...7BfGi98ObWqKnD8o4pv....JQklgmblCs=</Modulus><Exponent>AQAB</Exponent><P></P><Q></Q><DP></DP><DQ></DQ><InverseQ></InverseQ><D></D></RSAKeyValue>",
    "PrivateKeyXml": "<RSAKeyValue><Modulus>ip....lss7WqKnD8o4bKTp....IKbK2gaagCQ==</DP><DQ>BKOC....zlic+FQ==</DQ><InverseQ>JeIPWX....A==</InverseQ><D>iHU....cTrKeEGd</D></RSAKeyValue>"
  },

你能不能用 master 的最新源代码重试，因为我已经恢复了一些 RSA polyfills for .NET Core .
