Microsoft .NET PRNG

I have read both FoundStone's and @Stakes reviews of the PRNG included with
the Microsoft .NET 1.1 framework (also the Win32 CryptoAPI) , however there
is little information available (that I have been able to locate) that
discusses the actual method used, or an analysis of how reliable it is from
a cryptographic perspective.

I don't profess to be expert enough on random number generation and
cryptography to criticize the implementation, however I would like to know
more about it as most code samples I have seen and now an application I am
auditing is relying extensively on the CryptoAPI to provide facilities for
random key generation.

Does anyone have any technical resources which discuss concerns or
commendations of the implementation?
