Question

我正在浏览IdentityServer 3官方教程，我正在使用MVC应用教程（https://identityserver.github.io/Documentation/docsv2/overview/mvcGettingStarted.html），但我遇到了障碍。在“添加启动”部分，它可以让您下载要在应用程序中使用的证书，但我无法使其工作。

本地失败的示例代码是：

X509Certificate2 LoadCertificate()
    {
        return new X509Certificate2(
            string.Format(@"{0}\bin\identityServer\idsrv3test.pfx", AppDomain.CurrentDomain.BaseDirectory), "idsrv3test");
    }

但是，尽管证书在这个位置，我收到一个错误。我甚至尝试将证书复制到临时文件夹，所以我知道路径很好，

X509Certificate2 LoadCertificate()
        {
            return new X509Certificate2("c:\\temp\\idsrv3test.pfx", "idsrv3test");
        }

但它仍然失败并显示相同的消息：

Cannot find the requested object.

  Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

 Exception Details: System.Security.Cryptography.CryptographicException: Cannot find the requested object.

我也尝试使用不同的方法加载证书：

var stx = File.Open(@"c:\temp\idsrv3test.pfx", FileMode.Open);
            using (BinaryReader br = new BinaryReader(stx))
            {
                return new X509Certificate2(br.ReadBytes((int)br.BaseStream.Length), "idsrv3test");
            }

但是这给出了完全相同的错误，因此我认为加载文件本身并不存在问题。

有没有人遇到过这个问题？似乎其他人之前在SO上遇到过类似的问题，但没有发布与上述相符的确切解决方案。

我猜这不是文件的实际定位问题，而是其他问题，但我不知道那可能是什么......

由于

尝试加载新的X509证书时找不到请求的对象
