NlogViewer is a simple WPF-control to show NLog-logs. It's heavily inspired by this blog.

Forked from erizet/NlogViewer

Add a namespace to your Window, like this:

    xmlns:nlog ="clr-namespace:NlogViewer;assembly=NlogViewer"

then add the control.

    <nlog:NlogViewer x:Name="logCtrl" /> 

To setup NlogViewer as a target, add the following to your Nlog.config.

  <extensions>
    <add assembly="NlogViewer" />
  </extensions>
  <targets>
    <target xsi:type="NlogViewer"
            name="ctrl"
            autoScroll="true"
            maxLines="100"
            lastSelect="true" />
  </targets>
  <rules>
    <logger name="*" minlevel="Trace" writeTo="ctrl" />
  </rules>

<target xsi:type="NlogViewer"
        name="String"
        autoScroll="Boolean"
        maxLines="Integer"
        lastSelect="Boolean" />
