C# 引发异常：根据验证过程，远程证书无效

你好

我正在Visual Studio 2019上的一台PC（Windows 10）上运行ASP.NET CORE Blazor应用程序，它工作正常。我用VS代码在另一台PC（Windows7）上打开了同一个项目，并引发了以下异常

请帮忙

提前感谢。

当您使用VS 2019运行代码时，它会在您的计算机上安装一个自签名证书，用于https重定向。（将显示一个消息框，通知证书安装）

但是VS代码并不适合你

阅读此文档应有助于：

您可以尝试运行此命令

dotnet开发人员证书https--clean
dotnet开发人员证书https--信任

来自火星的agua的回答没有考虑到您还必须生成本地开发证书，然后才能告诉您的操作系统信任它

您可以按此顺序运行命令，然后再次运行应用程序

dotnet dev-certs https --clean
dotnet dev-certs https
dotnet dev-certs https --trust

---

命令

dotnet dev certs https

生成证书。

我已经执行了几次这些命令并重新启动了两次，但是错误仍然发生。还有指针吗？@ChrisBordeman您是否尝试使用

dotnet run

命令启动项目？是的，效果相同。奇怪的是Chrome甚至iexplore都说证书今天早些时候过期了，就在我开始出现问题的时候。我已转到MMC删除个人计算机和本地计算机中的所有本地主机证书，以及两者的受信任根证书。然后我尝试再次清理/安装它们，这似乎是成功的，我甚至清除浏览器缓存并重新启动。Chrome仍然说证书无效，今天过期了！我还清除了SSL名单。无法想象这是从哪里来的。@ChrisBordeman看起来很傻，但你的约会是最新的吗？是的。我最终重新安装了VS和所有SDK/工具。然后是所有的窗户。下一个选择是hara kiri。

dotnet dev-certs https --clean
dotnet dev-certs https
dotnet dev-certs https --trust
