Kind of strange how this class type has dropped of the F# released with VS2010
Does anyone know where it has gone? or where it is now?
回答1:
It is in the F# powerpack, which is used by the F# team for "unstable" code that will get released and updated more often than the main release of F# and libraries. (Note that the code is still high-quality code, you should ignore most of the connotations that "unstable" has in this case). It's just a way for the F# team to get more experimental code out there quickly, once F# is released for real.
The powerpack is on codeplex
