    "language_worker_restarts": 10
  }
}

3. Save the changes to the hostSettings.json file.
4. In your Startup.cs file, add the following code to configure the language worker process:

public void ConfigureServices(IServiceCollection services)
{
    services.AddLanguageWorker(options =>
    {
        options.RestartCount = 10;
        options.RestartTimeout = TimeSpan.FromSeconds(10);
