c# - How do I use Microsoft Application Insights with NLog (Target cannot be found: 'ApplicationInsights')

I am using Microsoft Application Insights for my Web Application. I used the Application Insights TraceListener NuGet package for logging. That worked perfectly.

Now I would like to switch to NLog. I added the Microsoft.ApplicationInsights.NLogTarget NuGet package and added a new NLog target in my NLog configuration file:

<target name='ai' xsi:type='ApplicationInsights' />

NLog throws an exception:

Target cannot be found: 'ApplicationInsights'

I also tried adding the assembly via extensions like so:

<extensions>
    <add assembly="Microsoft.ApplicationInsights.NLogTarget" />
</extensions>    

But it did not work either.

Any suggestions?

Solution: (thanks to @nemesv for the tip)

Programmatically add the target with

ConfigurationItemFactory.Default.Targets.RegisterDefinition(
    "ApplicationInsightsTarget", 
    typeof(Microsoft.ApplicationInsights.NLogTarget.ApplicationInsightsTarget)
);

and use it with

<target name='ai' xsi:type='ApplicationInsightsTarget' />
