Support of constructor parameters

[skomis-mm]

Added support for constructor parameters (implementation of second design) including nested configurations and type binding that StringArgumentValue supports.

"formatter": {
  "type": "Serilog.Formatting.Compact.CompactJsonFormatter, Serilog.Formatting.Compact",
  "valueFormatter": {
    "typeTagName": "customTypeTag"
  }
},

"formatter": {
    "type": "Serilog.Templates.ExpressionTemplate, Serilog.Expressions",
    "template": "[{@t:HH:mm:ss} {@l:u3} {Coalesce(SourceContext, '<none>')}] {@m}\n{@x}",
    "formatProvider": "System.Globalization.CultureInfo::InvariantCulture"
}

1. Prefix $ for type is optional to go in line with level/filter swithes declaration syntax
2. Ctor overload matching follows the same algorithm that is used in configuration method matching

• fixes Support Serilog expressions in sink configuration #276, Serilog console logging with JsonFromatter #225, Is it possible to specify value for named parameters of constructor #167

Just had one minor query; looks good to me. Seems like it would be wise for us to queue up a 3.3.0 release shortly after merging - the world needs this! :-D

I apologise given this is an old PR, but how do you pass a constructor argument using config?

I am trying to pass the renderMessage:true argument to the inbuilt JsonFormatter, but cannot see given the example above how to do this (nor by reading the linked issue).

If i try what seems indicated:

"formatter": {
    "type": "Serilog.Formatting.Json.JsonFormatter",
    "renderMessage": true
}

I get:

I've got the same or a simmilar problem as @WattsC-90

This is in my appsettings.json

"Name": "Console",
"Args": {
  "formatter": {
    "type": "Serilog.Templates.ExpressionTemplate, Serilog.Expressions",
    "template": "[{@t:HH:mm:ss} {@l:u3} {Coalesce(SourceContext, '<none>')}] {@m}\n{@x}",
    "formatProvider": "System.Globalization.CultureInfo::InvariantCulture"
  }
}

And this is the exception

System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.

Same for me when using type and template. Works with JSON formatter.

I know this is a late reply, but I got it working with the following code. The difference is including "Serilog" in the type which I'm assuming is the name of the Nuget Pacakge?

"WriteTo": [
  {
    "Name": "Console",
    "Args": {

      }
    }
  }
