【问题描述】:
我收到以下错误。这似乎是在我升级我的 Visual Studio 2015 以进行第一次更新后才开始的。我在这里阅读了一些关于这与机器密钥有关的问题?我不知道如何解决它并防止它。目前,当我使用 IIS express 在调试中运行此程序时,我在本地计算机上遇到此错误。
Exception Details: System.Security.Cryptography.CryptographicException: Error occurred during a cryptographic operation.
Cache = db.UserTokenCacheList.FirstOrDefault(c => c.webUserUniqueId == userId);
// place the entry in memory
this.Deserialize((Cache == null) ? null : MachineKey.Unprotect(Cache.cacheBits,"ADALCache"));

【问题讨论】:
-
正确的堆栈跟踪将有助于理解您的问题。
-
你能检查一下那个线程吗:blogs.msdn.com/b/webdev/archive/2012/10/23/… .config 文件中有一整节关于与 machineKey 设置的兼容性。
-
谢谢,我去看看。我不明白为什么突然停止工作。如果在生产中发生这种情况,我会担心
-
如果更新以某种方式破坏了您的 iis express 证书/密钥(这可能是您问题的根源),请尝试转到添加/删除程序并选择 IIS Express 上的“修复”选项。这样证书将重新安装。
-
它什么都没有。修复了visual studio和iis,同样的问题
