-If you intend on using any of the Serilog semantic logging formats in your logging strings, __you need to use the SerilogLoggingAdapter__ inside your instrumented code or there could be elsewhere inside parts of your `ActorSystem`:
-```csharp
-var log = Context.GetLogger&lt;SerilogLoggingAdapter&gt;(); // correct
-log.Info("My boss makes me use {semantic} logging", "semantic"); // serilog semantic logging format
-```
-This will allow all logging events to be consumed anywhere inside the `ActorSystem`, including places like the Akka.NET TestKit, without throwing `FormatException`s when they encounter semantic logging syntax outside of the `SerilogLogger`.</PackageReleaseNotes>
