 You should use [ILogger](/dotnet/api/microsoft.xrm.sdk.plugintelemetry.ilogger) because it will allow for telemetry about what happens within a plug-in to be integrated with the larger scope of data captured with the Application Insights integration. The Application Insights integration will tell you when a plug-in executes, how long it takes to run and whether it makes any external http requests, but Microsoft cannot add any telemetry code within the plug-ins that people write to extend the behavior of the platform.
 
-If you are an ISV with a product that includes plug-ins, your customers who enable Application Insights will appreciate being able to see what is going on within your plug-ins and this data may help you support them if there are issues. But data captured using ILogger will only be sent to the subscribing customer’s resource. You will only be able to see data captured for your own environments when you have Application Insights enabled.

 ## Use ILogger
 
 ILogger is a common interface for capturing log information. The implementation provided with the Organization Service SDK assemblies provides common methods to support establishing a scope and different levels of logging.  There is currently no setting to control what level of logs are written. The levels can be used within Application Insights to filter which logs to view.
 
 The following is an example of a plug-in using both ILogger and ITracingService.Trace.
 
+> [!NOTE]
+> Make sure you include `using Microsoft.Xrm.Sdk.PluginTelemetry;`. Don't use `using Microsoft.Extensions.Logging;`, otherwise the `Ilogger` instance will be null.
