CompilerContext is a special SRE mode that enables some extra features that
mcs
used to require. Since the 2.8 release mcs no longer requires it and this is
going away
for the 3.0 release. Else so, this is an internal flag that it's not meant
for general use.

The "Operation is not supported" problem is caused by F# using an instance
of a TypeBuilder
instead of a runtime type. Somewhere in the guts of mono' s SR(E) where
doing something
different from what F# expect and everything breaks.

There is a bugzilla entry tracking this problem:
