如何等待 ASP.NET Core 6.0 Runtime 的静默安装

Question

我想等到 dotnet 托管捆绑包安装完成。通常会有某种返回代码：

• 0 -> 好的
• <1 -> 错误

PS D:\app> .\dotnet-hosting-6.0.4-win.exe /install /passive /norestart

Msi不存在，还有其他办法吗？

我们通过循环运行下一个命令来解决这个问题：

using System.ComponentModel;
using System.Diagnostics;

bool found = false;

// 36 * 5s = 180s = 3 minutes 
for (int i = 0; i < 36; i++)
{
  try
  {
    using Process p = new();
    if (!string.IsNullOrWhiteSpace(Environment.GetEnvironmentVariable("SYSTEMROOT")))
    {
        p.StartInfo.WorkingDirectory = Environment.GetEnvironmentVariable("SYSTEMROOT");
    }

    p.StartInfo.FileName = "dotnet";
    p.StartInfo.Arguments = "--list-runtimes";
    p.Start();

    // additionally we can search for desired runtime
    found = true;
    break;
  }
  catch (Win32Exception)
  {
    // command is not available yet
  }

  Thread.Sleep(5000); 
}

运行时示例：
