Linking Custom Config File to Machine Config File

  • Article

There is configSource attribute with help of which content of the Machine.config file can be redirected to the custom config file.

 

Below is the sample

 

<system.diagnostics configSource="GlobalDiagnostics.config">

</system.diagnostics>

 

For the system diganostic section in machine.config file a seperate  config file is been created, file name is GlobalDiagnostic.config. Global diagnostic file can then contain the diagnostics related configurations. Below is the sample content of the  

 

<?xml version="1.0" encoding="utf-8"?>

<system.diagnostics>

  <sharedListeners>

    <add name="CustomTraceListener" type="Instrumentation.Framework.CustomTraceListener, Instrumentation.Framework, Version=1.0.0.0, Culture=neutral, PublicKeyToken=b40e65bd72b277e3" traceOutputOptions="LogicalOperationStack" />

  </sharedListeners>

  <switches>

    <add name="Debug" value="Verbose,ActivityTracing" />

    <add name="TraceSourceSwitch" value="All" />

  </switches>

  <trace autoflush="true" indentsize="4" />

  <sources>

    <source name="TestEventSource" switchType="System.Diagnostics.SourceSwitch" switchName=" TraceSourceSwitch ">

      <listeners>

        <remove name="Default" />

        <add name="CustomTraceListener" />

      </listeners>

    </source>

  </sources>

</system.diagnostics>

 

But this has limitation that config file must be in the same or sub folder, the path has to be below the current path of the machine config file.
