3 out of 27 Unit Tests are failing on Windows 7, but run ok on Windows 10

Hi,

The following 3 tests are failing on Windows 7, but run ok on Windows 10:

1. ImportExportRsaPrivateKeyPublicKeyPairPem()
2. ImportExportSingleChainedECPrivateKeyPublicKeyPairPem()
3. ImportExportECPrivateKeyPublicKeyPairPem()

They are all failing with the Excepton:

"Internal.Cryptography.CryptoThrowHelper+WindowsCryptographicException : The specified network password is not correct."

Is there some further preparation to run these Tests successfully on Windows 7, some code changes required, or is this a known limitation of ASPNetCore on Windows 7 (e.g. rather like no .NET ALPN support in Win7)?

Exception stack trace details are listed below.

@jlewis666 thanks for reporting, I would need to look into this, no idea why

This might be a well known issue in Windows 7 where the creation of a X509Certificate2 needs access to the machine key set: https://stackoverflow.com/questions/8286110/asp-net-the-specified-network-password-is-not-correct
