<introduction>
<para>The Json.NET serializer supports logging and debugging using the
<codeEntityReference>T:Newtonsoft.Json.Serialization.ITraceWriter</codeEntityReference> interface.
By assigning a trace writer you can capture serialization messages and errors and debug what happens inside the
Json.NET serializer when serializing and deserializing JSON.</para>

<para>Json.NET has two implementations of ITraceWriter: <codeEntityReference>T:Newtonsoft.Json.Serialization.MemoryTraceWriter</codeEntityReference>,
which keeps messages in memory for simple debugging, like the example
above, and <codeEntityReference>T:Newtonsoft.Json.Serialization.DiagnosticsTraceWriter</codeEntityReference>, which writes messages to any
System.Diagnostics.TraceListeners your application is using.</para>
