MailKit Dependency Injection With Quartz

[faisalbwn]

Dear Daniel,

I am injecting the MailKitSimplifiedEmailReceiver in QuartzHostedService and using it in Quartz job, but due to following error Quartz job is not firing again, also the log is not being written:

warn: MailKitSimplified.Receiver.Services.LogFileWriterQueue[0]
Log queue cancelled while logs are still being written.
fail: Quartz.Core.QuartzSchedulerThread[0]
Runtime error occurred in main trigger firing loop.
System.ObjectDisposedException: Cannot access a disposed object.
Object name: 'LoggerFactory'.

I thought this might become an issue, but no one had complained about it so I wasn't sure. Here's the reason from Microsoft: "Services resolved from the container should never be disposed by the developer." https://learn.microsoft.com/en-us/dotnet/core/extensions/dependency-injection-guidelines#disposal-of-services

Please check the latest preview release.

Thanks Daniel.
I updated to pre-release and it fixed the issue. But there is one more issue related to it, I am giving the "ProtocolLog" path in appSetttings.json but it is not creating the log files for both sender and receiver.
Can you please guide for sender and receiver logging.

I'd written my own file writer that was set as follows: "ProtocolLogger:FileWriter:FilePath": "Logs\\ImapClient.txt"
I've fixed it in the latest pre-release so you can use the method in the documentation again: "ProtocolLog": "Logs\\ImapClient.txt"

Please check it works and close this issue if it does.

Thanks for helping out Daniel. Closing the ticket and looking forward for stable release.

Jeffrey Stedfast himself (of MailKit fame) replied to our query with some suggestions on how to improve performance by using UniqueIdSet with UniqueIdRange, so please try out the latest release.
