This is a bug in F# Interactive when used from Visual Studio (or more precisely when used with the --qutoation-data flags, which was on by default when used from Visual Studio in this release).
The problem stems from the last two definitions, but is hard to workaround. Until we get a bug fix release out (which we plan for the next couple of days) the best workaround is to use F# Interactive (fsi.exe) from the command line.

I'm a f# newbie and I just ran into this error with 1.9.1.8. This works fine with the standalone compiler.
I don't really have enough experience to track this down any further and I was wondering if someone might be able to point out what I'm doing wrong. Thanks in advance!
p.s. sorry for the formatting
