Working with nCover to examine the number of code-points represented by any given method, the October CTP made a large number of changes -- some up, some down -- to the code generated by the compiler.
Most interesting is the change to attribute setters, which used to be NOP;assign;return and are now just assign;return. Also the name of the implicit backing field has changed to be the property name with an appended '@', rather than being a case-mangled version of the property name.
(As always, talking about Debug builds).
Later ... This one is a bit too cryptic for me to decipher what I was writing about. Code like this:
Has internal fields like
Line@ still at 220.127.116.11; and property setters as in
compile to the NOP-bearing
with the Feb 2010 CTP.
