RollingFile + JsonFormatter from config = plain text logs

[andersnm]

Am unable to enable the JsonFormatter with RollingFile from a configuration file. Any insight would be appreciated, presumably I'm missing something obvious

Have updated all package versions, made sure to using "formatter" as the type parameter, and carefully pasted the typename per the only documentation I could find:
http://stackoverflow.com/questions/40880261/configuring-serilog-rollingfile-with-appsettings-json
#31

Have tried to delete all Serilog.* packages from my .nuget folder and refresh. Have tried both older/newer version of the serilog and configuration packages. Made no difference though.

project.json:
"Serilog": "2.3.0",
"Serilog.Extensions.Logging": "1.4.0",
"Serilog.Enrichers.Environment": "2.0.0",
"Serilog.Enrichers.Process": "2.0.0",
"Serilog.Enrichers.Thread": "2.0.0",
"Serilog.Sinks.RollingFile": "2.0.0",
"Serilog.Sinks.Seq": "2.0.0",
"Serilog.Sinks.ColoredConsole": "2.0.0",
"Serilog.Settings.Configuration": "2.2.0"

config.json:
"Serilog": {
"Using": [ "Serilog.Sinks.RollingFile" ],
"MinimumLevel": "Debug",
"WriteTo": [
{
"Name": "RollingFile",
"Args": {
"pathFormat": "c:\logs\application\log-{Date}.json",
"formatter": "Serilog.Formatting.Json.JsonFormatter, Serilog",
"retainedFileCountLimit": "7"
}
}
],
"Enrich": [ "WithMachineName", "WithThreadId", "WithProcessId" ]
}

Unexpectedly this generates log files in plain text (altho in the expected location!). The JsonFormatter configuration is silently ignored:

2017-03-14 15:18:51.627 +01:00 [Information] Request starting HTTP/1.1 GET http://localhost:49652/
etc

The app targets the full .NET framework 4.5.1

@andersnm , I think you need upgrade RollingFile package to at least version 2.1.0
see this

Obvious indeed, found my own problem after trying some random stuff

It works when updating the rolling file package:
"Serilog.Sinks.RollingFile": "2.2.0",

Also thanks @skomis-mm
