How to wait for silent installation of ASP.NET Core 6.0 Runtime

Question

I want to wait until dotnet hosting bundle is installed. Usually there would a some sort of return code:

• 0 -> ok
• < 1 -> error

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

Msi doesn't exist, is there any other way?

Answer 1

We solved it by running next command in a loop:

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); 
}

You can try to use Start-Process -Wait to run the installer and wait for it to finish:

Start-Process .\dotnet-hosting-6.0.4-win.exe -ArgumentList "/install /passive /norestart"

I didn't test it on ASP.NET Core Runtime 6.0 but I had similar problem with installing .NET SDK 6.0. Running in Powershell just this command as described in docs:

./dotnet-sdk-6.0.403-win-x64.exe /install /quiet /norestart 

started the installation process but immediately returned to Powershell (the installation continued in the background). It seems that .exe and .msi installers works that way and you need to use start /wait in cmd or Start-Process -Wait in Powershell to wait in terminal/script for the process installation to finish. Like this:

Powershell

Start-Process -Wait 'C:\dotnet-sdk-6.0.410-win-x64.exe' -ArgumentList '/install /quiet /norestart';

cmd

start /w C:\dotnet-sdk-6.0.410-win-x64.exe /install /quiet /norestart
