与@mythz进行了漫长的交谈之后，事实证明，必须以Admin模式运行VS才能运行"AppHostHttpListenerBase".

After a lengthy conversation with @mythz, it turns out that VS has to be run in Admin mode for the "AppHostHttpListenerBase" to run.

从终端运行./build时，我还必须以管理员身份运行Powershell.

I also have to run Powershell as Admin when running ./build from the terminal.
