Serilog only logging to File with version 3 of Serilog

See original GitHub issue

I couldn’t get Serilog to log to a file with the API template 2.2.0. I upgraded Serilog.AspNetCore from 2.1.1 to 3.0.0 and this fixed the error. Not sure if there was another way to get it to work, but the upgrade worked.


"WriteTo": [
        "Name": "Console",
        "Theme": "Code"
      { "Name": "Debug" },
        "Name": "File",
        "Args": { "path": "%TEMP%\\Logs\\example.txt" }

Yeah I think that’s an issue with our template. Will probably be resolved when we push it to Core 3.

Oh ok that makes sense. I’m only using the appsettings that come with the Api template, and then I’ve just added File as an extra sink without the necessary config. I’ll have a look at that sample config link you sent as there might be some settings I want to bring into my project. Thanks for the quick responses and I’ll close this issue 😃
