NLog logging adapter for OWIN!

## Installation

There's a nuget package you can install this way:

> Install-Package NLog.Owin.Logging

## Using

To use the NLogAdapter with its default configuration:

```C#

using NLog.Owin.Logging;

public class Startup

{

	public void Configuration(IAppBuilder app)

	{

		app.UseNLog();

	}

}

```

The default translation table is:

| TraceEventType	| NLog Loglevel |

|-------------------|---------------|

| Critical			| Fatal			|

| Error				| Error 		|

| Warning			| Warn 			|

| Information		| Info 			|

| Verbose			| Trace 		|

| Start				| Debug 		|

| Stop				| Debug 		|

| Suspend			| Debug 		|

| Resume			| Debug 		|

| Transfer			| Debug 		|

If you'd like to customize this translation table you can supply a `Func` to the extension above.

```C#

using NLog.Owin.Logging;

using NLog;

using System.Diagnostics;

public class Startup

{

	public void Configuration(IAppBuilder app)

	{

		// make a warning out of every log message!

		app.UseNLog((eventType) => LogLevel.Warn);

	}

}

```

## Note / Information

(Added in version 1.1) 

Any `EventId` passed to this `Microsoft.Owin.Logging.ILogger.WriteCore()` implementation is passed down to NLog in the log event's properties, and can be written to output by adding the matching line in the Log appender layout:

```

${event-properties:item=EventId}

```
