= Using OPC NET API implementation =
If you want to use the OPC NET API implementation  instead of the native implementation (in OpcCmd for .NET Framework), you can do it interactively as in the following example:
<pre>
OpcCmd -i
aeclient --property InstanceParameters.EnableNativeClient=[Boolean]false
subscribeEvents subscribeEvents OPCLabs.KitEventServer.2
</pre>
If you want to use such setting permanently, you can modify one of the OpcCmd [[Intrinsic Component Configuration]] files (JSON, INI or XML). For example, with the JSON format, put the following into the '''appsettings.json''' or '''appsettings.production.json''' file:
<syntaxhighlight lang="json">
{
  "OpcLabs.EasyOpc.AlarmsAndEvents.EasyAEClient": {
    "InstanceParameters": {
      "EnableNativeClient": false
    }
  } 
}
</syntaxhighlight>
