用法

使用 Spectre.Console.Rx 动画一些状态、表格和进度条的示例。

using System.Reactive.Concurrency;
using System.Reactive.Linq;
using ProgressDemo;
using Spectre.Console.Rx;

// NOTE: This code executes synchronously, only one instance of the console context can be executing at a time.
//       This is because the console context is not thread safe.
//       Remember to call IsFinished() on the console context when you're done with it.
