Use .Net Core Generic Service and Quartz to Implement Background Schedule Tasks.
Create a console application. And install the package:
PM> Install-Package Quartz.HostedService
These packages may also need:
PM> Install-Package Microsoft.Extensions.Hosting
PM> Install-Package Microsoft.Extensions.Configuration.Json
PM> Install-Package Microsoft.Extensions.Logging.Console
PM> Install-Package Microsoft.Extensions.Logging.Debug
Edit the quartz configuration in the appsettings.json:
{
"Logging": {
"LogLevel": {
"Default": "Warning"
}
},
"quartz": {
"scheduler": {
"instanceName": "Quartz.HostedService.Sample"
},
"threadPool": {
"type": "Quartz.Simpl.SimpleThreadPool, Quartz",
"threadPriority": "Normal",
"threadCount": 10
},
"plugin": {
"jobInitializer": {
"type": "Quartz.Plugin.Xml.XMLSchedulingDataProcessorPlugin, Quartz.Plugins",
"fileNames": "quartz_jobs.xml"
}
}
}
}Write your job(s):
public class TestJob : IJob
{
private readonly ILogger _logger;
public TestJob(ILogger<TestJob> logger)
{
_logger = logger;
}
public Task Execute(IJobExecutionContext context)
{
_logger.LogInformation(string.Format("[{0:yyyy-MM-dd hh:mm:ss:ffffff}]Test job is running...", DateTime.Now));
return Task.CompletedTask;
}
}Prepare the quartz_jobs.xml:
<?xml version="1.0" encoding="UTF-8"?>

</job-scheduling-data>Add generic host, register quartz hosted service and job(s) in the Program.cs:
static void Main()
{
var host = new HostBuilder()
.ConfigureHostConfiguration(configHost =>
{
configHost.SetBasePath(Directory.GetCurrentDirectory());
})
.ConfigureAppConfiguration((hostContext, configApp) =>
{
configApp.AddJsonFile("appsettings.json", true);
})
.ConfigureServices((hostContext, services) =>
{
services.AddLogging();
services.AddQuartzHostedService(hostContext.Configuration);
services.AddSingleton<TestJob, TestJob>();
})
.ConfigureLogging((hostContext, configLogging) =>
{
configLogging.AddConsole();
configLogging.AddDebug();
})
.UseConsoleLifetime()
.Build();
host.Run();
}For more details about generic host please refer:
