Application Logging in .Net Core with Seq 5 and Serilog

I have used quite a few logging frameworks in the past such as Log4Net and Splunk. However, most of them aren’t particularly useful for tracking down errors and seeing how your service is performing. I started using Seq with Serilog when I was working at my last company and it is amazing what a difference it can make having useful searchable logs.

What is Seq?
