In .NET Framework 4.5.2, X509Certificate2 does implement IDisposable

I have code that iterates an array of objects that dispose objects that implement IDisposable. In .net 4.5.2, the certificates do in fact get disposed and all references become invalid. I did not check prior versions. The remarks for this class are wrong/misleading and need to be updated.
