Hangfire generates lots of "ObjectDisposedException" exceptions on very simple application
I create very simple application - winforms with NuGet packages Hangfire.Core and Hangfire.SqlServer.
Hangfire initializes with two strings
GlobalConfiguration.Configuration.UseSqlServerStorage(Properties.Settings.Default.ConnectionString);
_server = new BackgroundJobServer();
Jobs are adds with this string
var name = DateTime.Now.Ticks.ToString();
RecurringJob.AddOrUpdate(name, () => Console.WriteLine($"job '{name}'"), Cron.MinuteInterval(1));
Link on the screenshot https://c2n.me/3ZHcBcd
After adding some jobs i see lots of "Exception thrown: 'System.ObjectDisposedException' in System.Transactions.dll" in output window. This problem comes with 1.6.17, 1.6.22, 1.7 versions. Its terrible problem becouse i cant normally work with Output window - i need to analyze information about potentially important exceptions but not about Hangfire transactional games.

Have the same issue:
We use .Net Core in Full Framework 4.7.2. And the config:
"Dashboard": {
"AppPath": "/swagger/index.html?url=/swagger/v1/swagger.json",
"StatsPollingInterval": 2000
},
"Server": {
"HeartbeatInterval": "00:00:30",
"Queues": [ "default" ],
"SchedulePollingInterval": "00:00:15",
"ServerCheckInterval": "00:04:00",
"ServerName": null,
"ServerTimeout": "00:04:00",
"ShutdownTimeout": "00:00:15",
"WorkerCount": 20
}
Happens every minute on one machine and only on start on another.
Hope this can help a bit..

This is the example application - https://c2n.me/3ZXFgmx

Those exceptions are not generated by Hangfire, neither it can choose not to log them. This is how DbConnectionInternal.EnlistedTransactionDisposed is actually implemented:
c#
protected bool EnlistedTransactionDisposed
{
get
{
try
{
Transaction enlistedTransactionOriginal = _enlistedTransactionOriginal;
if (enlistedTransactionOriginal != null)
{
return enlistedTransactionOriginal.TransactionInformation == null;
}
return false;
}
catch (ObjectDisposedException)
{
return true;
}
}
}
You probably have "Enable Just My Code" option disabled in Debugger settings, so it would log exceptions from anywhere, not just those coming from your code. Enabling it back would help.
Alternatively, you can exclude any exception messages from the Output window. It's not like they're very helpful anyways.
