NLog provider for Microsoft.Extensions.Logging; DNX and ASP.NET 5.
Routes ASP.NET 5 log messages to NLog.
- Create nlog.config in root of your project file.
- in startup.cs add in
Configure
public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
//add NLog to aspnet5
loggerFactory.AddNLog();
//configure nlog.config in your project root
env.ConfigureNLog("nlog.config");
...- You need to configure where the nlog.config is located (see example above)
- Installing the NuGet packages NLog.config / NLog.schema won't add to your project.
${basedir}refers toC:\Users\...\.dnx\runtimes\dnx-clr-win-x86.1.0.0-rc1-update1\bin- auto load of NLog extensions won't work yet.
- This work only for "Microsoft.Extensions.Logging" RC1 as there are breaking changes in RC2 (not released yet)
- You need NLog 4.4 (alpha now) for CoreCLR
- The levels of Microsoft.Extensions.Logging can be confusing. In Microsoft.Extensions.Logging RC1,
debugis lowest level and notverbose. This has been fixed in Microsoft.Extensions.Logging RC2 - which isn't released yet.
Overview:
| Microsoft RC1 | Microsoft RC2 | NLog |
|---|---|---|
| Critical | Critical | Fatal |
| Error | Error | Error |
| Warning | Warning | Warn |
| Information | Information | Info |
| Verbose | Debug | Debug |
| Debug | Trace | Trace |
So in RC1, debug in Microsoft is trace in NLog!
Please give feedback here!
