Child Elements


Parent Elements

Element Description
configuration The root element in every configuration file used by the common language runtime and .NET Framework applications.
listeners Specifies a listener that collects, stores, and routes messages. Listeners direct the tracing output to an appropriate target.
system.diagnostics Specifies trace listeners that collect, store, and route messages and the level where a trace switch is set.
trace Configures the ASP.NET trace service.


[!NOTE] Removing the xref:System.Diagnostics.DefaultTraceListener from the Listeners collection alters the behavior of the xref:System.Diagnostics.Debug.Assert%2A?displayProperty=nameWithType, xref:System.Diagnostics.Trace.Assert%2A?displayProperty=nameWithType, xref:System.Diagnostics.Debug.Fail%2A?displayProperty=nameWithType, and xref:System.Diagnostics.Trace.Fail%2A?displayProperty=nameWithType methods. Calling an Assert or Fail method normally results in the display of a message box, however the message box is not displayed if the xref:System.Diagnostics.DefaultTraceListener is not in the Listeners collection.


The following example shows how to remove the default trace listener from the trace Listeners collection.

      <trace autoflush="true" indentsize="0">  
            <remove name="Default" />
