使用 .net Core 3.1 的 Kestrel ssl JSON 配置中的证书问题

我已经看到这个问题的答案，但它似乎不适用于 .net core 3.1 此代码查找证书：

using (var store = new X509Store("Root", StoreLocation.LocalMachine))
{
    store.Open(OpenFlags.ReadOnly);
    var certCollection = store.Certificates;  
    var currentCerts = certCollection.Find(X509FindType.FindBySubjectName, "*.timedesk.com", false);
    if (currentCerts.Count == 0)
        throw new Exception("Https certificate is not found.");
}

这个appsettings.json没有找到证书：

"Kestrel": {
  "Endpoints": {
    "Https": {
      "URL": "https://toast.timedesk.com:443",
      "Scheme": "https",
      "Certificate": {
        "Store": "Root",
        "Location": "LocalMachine",
        "Subject": "*.timedesk.com",
        "AllowInvalid": false
      }
    }
  }
}

给出以下错误：

System.InvalidOperationException: 'The requested certificate *.timedesk.com could not be found in LocalMachine/Root with AllowInvalid setting: False.'

我发现了这个问题，服务器上的证书没有私钥。一旦我得到了私钥，它就开始工作了。显示它现在拥有私钥的证书 https://i.stack.imgur.com/Nl6PC.png
