StackExchange.Redis using TLS Certificate Errors

Question

I have installed Redis locally and configured TLS:

redis.conf

tls-cert-file ~/my.crt.pem
tls-key-file ~/my.key.pem
tls-ca-cert-file ~/ca_root.crt

I can use redis-cli to connect to it just fine by:

redis-cli --tls --cert ~/my.crt.pem --key ~/my.key.pem --cacert ~/ca_root.crt

and that works great. How do I setup StackExchange.Redis.ConfigurationOptions properly for TLS to work from a .NET app? No maatter what I do, I get certificate errors or mismatch.
