.Net SDK private key issue

We facing issue with private key in new version dotnet sdk. when we try to signing xml we getting error in the screen shot

We trying putted private key

  • in one line,
  • with include -----BEGIN EC PRIVATE KEY-----
  • and with out header
  • and also in on line with \n.

but also not work.

kindly try the latest version (3.3.2) with the dummy certificate and private key first. The private key should be added without headers.
