Lines marked with 'compile error comment emit a compile error from the c# compiler phase. The earlier lines doing the same thing ( marked #OK) compiles OK.
using int32 ( defaults - no u?? on literals) compiles fine.
if I cast the # compile error lines
- Code: Select all
b1 = (b1 & 31u8) to uint8
get a warning from cobra but compiles and runs fine.
