Answer 1

Windows.Security.Cryptography is a WinRT API. Windows Phone 8 still being mostly Silverlight uses the APIs from System.Security.Cryptography, which does not include the SymmetricKeyAlgorithmProvider.

You can still use the AesManaged API on Windows Phone, which may, or may not, be enough for your purpose.

Windows.Security.Cryptography is most likely just the x86 COM abstraction of the Microsoft cryptolib, which is the same as most of System.Security.Cryptography on .NET 3.5-4.0
