asp.net - Using NLog with asp-net layout renderers in AspNet vNext (MVC 6) -

i trying integrate nlog in aspnet 5 (or using new name aspnet core 1.0) web app. not sure if possible @ want log logged in user. nlog config file.

<?xml version="1.0" encoding="utf-8" ?> <nlog xmlns="http://www.nlog-project.org/schemas/nlog.xsd"       xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"       autoreload="true">   <targets>     <target name="logfile"             xsi:type="file"             filename="file.txt"             layout="${longdate}|${message}|${identity}|${aspnet-user-identity}" />   </targets>   <rules>     <logger name="webapplication2.*" minlevel="info" writeto="logfile" />   </rules> </nlog> 

the thing

system.argumentexception: layoutrenderer cannot found: 'aspnet-user-identity'

my project.json file looks like:

  "dependencies": {     .....     "nlog.framework.logging": "1.0.0-rc1-final",     "nlog": "4.4.0-alpha1",     "nlog.config": "4.3.0-beta1",     "nlog.extended": "4.0.0-rc",     "nlog.web": "4.1.0"   }, 

maybe missing something, or not yet supported nlog ?

edit: found out auto load of extensions not supported. so, have modify nlog.config like:

 <extensions>     <add assembly="nlog.web"/>     <add assembly="nlog.extended"/>   </extensions> 

but blank input current user. ideas ?

the internal log give more info why loading extension failed.

there other ways load extensions, assemblyfile attribute , programmatically:

//target configurationitemfactory.default.targets                         .registerdefinition("myfirst", typeof(mynamespace.myfirsttarget));  //layout renderer configurationitemfactory.default.layoutrenderers                         .registerdefinition("hello-world", typeof(mynamespace.helloworldlayoutrenderer )); 

edit: did tests. works in loading assembly:

<extensions> <add assembly="nlog.web" /> </extensions>

but bad nlog.web isn't asp.net 5 compatible, yet. can't use httpcontext.current there.

edit: asp.net 5 compatible version of nlog.web available! see nuget
