ASP.Net Core 6 Free Error Logging NuGet Package RSEasyExceptionHandler.

Logging in Core 6! We should always add error login in our program and it should be in the better by now.

What do I mean, Logging frameworks and libraries, such as log4net, NLog, elmah, and Serilog, are widely used by developers for debugging code in the .Net ecosystem. These tools are known for their simplicity, ease of use, and effectiveness in capturing log data. However, while these logging tools are valuable, they may not be sufficient on their own and not free.

In this article, I am going to share a free NuGet package which will help you do to the following in the free of cost and package name is RSEasyExceptionHandler.

  1. 1.      Error Logging in Core 6 (API or Web Site)
  2. 2.      Auto save error log in the SQlite database
