Visual Studio 2013 运行项目两次

When I press the "Local Windows Debugger" button when working on any basic C++ project in Visual Studio 2013, the console opens and the program outputs, but when the console closes, another console opens, the UI changes slightly and the program outputs again.

重现步骤:

1. 创建一个新的 C++ 项目

    #include <iostream>

    using namespace std;

    int main() {
        cout << "Hello world!";
        cin.get();
    }
