Engineering can't use the first layer namespace "System"?


Use process after all xaml files will be an error


But if it is on the second floor, there is no issue, reserved keywords? Naming conflicts?

Although this is not a problem, avoid this name, but especially curious, what leads to the features of that?

Have know friends, don't have much time to study this problem does not affect the work, do not know can also go to a test,

CodePudding user response:

Naming conflicts,
Because the System is bringing some namespace,
You change to MySystem forget it
