X509Certificate2Collection.Find( ) documentation - missing information.

### Type of issue

Missing information

### Description

1. The validOnly parameter does not explain what "valid" actually means in the context of the Find operation. For example, does valid mean the current time is within the NotBefore and NotAfter times. Does it need to have a private key to be valid, etc?

2. No type information is given in terms of the expected data type for each of the possible X509FindType enumerations. For example, to use FindByThumbprint do I supply a string as a thumbprint or a byte array?
