Examples

The following sample configuration file enables tracing of animations, writing the output to a text file called "debug.txt".

<configuration>  
  <system.diagnostics>  
    <sources>  
      <source name="System.Windows.Media.Animation"  
switchName="SourceSwitch" >  
        <listeners>  
          <add name="textListener" />  
        </listeners>  
      </source>  
    </sources>  
    <switches>  
      <add name="SourceSwitch" value="All" />  
    </switches>  
    <sharedListeners>  
      <add name="textListener"  
           type="System.Diagnostics.TextWriterTraceListener"  
           initializeData="Debug.txt" />  
    </sharedListeners>  
    <trace autoflush="true" indentsize="4"></trace>  
  </system.diagnostics>  
</configuration>  

Remarks

Debug tracing is only available when a WPF application is running in full trust mode.

In order to enable tracing, you first must set a registry key, then you must configure trace sources.

  • To create the registry key, set a "ManagedTracing" reg_dword value to 1 under "HKeyCurrentUser\Software\Microsoft\Tracing\WPF".

  • To configure trace sources, create an application config file. This file has a .config extension, for example, XamlPad.exe.config.

Achieving optimal application performance requires forethought in application design and an understanding of best practices for Windows Presentation Foundation (WPF) application development. For more information, see Optimizing WPF Application Performance.
