Zub*_*ana 5 c# key-management azure asp.net-core-identity asp.net-core-2.1
仅当我在共享托管上部署 ASP .NET Core 2.1 Web 应用程序时，才会出现此问题。我将 Azure Key Vault 与 PersistKeysToFileSystem 结合使用。
Web 应用程序在我的开发计算机上以及使用 PersistKeysToFileSystem 的带或不带 Azure Key Vault 的 Azure 应用程序上运行良好。
fail: Microsoft.AspNetCore.DataProtection.KeyManagement.KeyRingProvider[48]
An error occurred while reading the key ring.
