I can run express and full.
In object browser of express I see nothing, in full I can see what's inside : a bunch of generic delegate types and some TimeZoneInfo types. I had hoped Numeric would be more "mathematically" inclined:'( It was just by accident I saw it was there and I was curious...
You guys helped me out very well thanks!
Actually System.Numeric contains a member, BigInteger a Value type. I tried IL DASM and found it different from the object browser. Unfortunately it is not accessible now. It contains really cool stuff and you cannot access it:P.See here for details if you have not already seen.
