In C# (3.5) I try the following: byte byte1 = 0x00; byte byte2 = 0x00; byte byte3 = byte1 & byte2; and I get Error 132: "Cannot implicitly convert type 'int' to 'byte'. An explicit conversion exists (are you missing a cast?)". The same happens with | and ^. What am I doing wrong? Why is it asking me about ints? Why can't I do bool...
