AutoCAD 2025 System.Windows.Data Error in visual studio output window

We used to be able to suppress these error message by editing the acad.exe.config and adding the following:

<system.diagnostics> <sources> <source name="System.Windows.Data" switchName="SourceSwitch"> <listeners> <remove name="Default" /> </listeners> </source> </sources> </system.diagnostics>

But that does not appear to work for AutoCAD 2025, and the snow of messages is giving me a sore head when I have to wade through the output looking for messages of 'real' interest. is there a new way to suppress these pointless error messages (pointless as there is nothing to be done about them!)

This should do the trick:

void IExtensionApplication.Initialize() { if (PresentationTraceSources.DataBindingSource.Listeners.Count > 0) { PresentationTraceSources.DataBindingSource.Listeners.Remove("Default"); } PresentationTraceSources.DataBindingSource.Listeners.Add(new FilteredTraceListener()); } public class FilteredTraceListener : DefaultTraceListener { public override void Write(string? message) { if (!IgnoreMessage(message)) { base.Write(message); } } public override void WriteLine(string? message) { if (!IgnoreMessage(message)) { base.WriteLine(message); } } private bool IgnoreMessage(string? message) { // Define logic to determine if the message should be ignored return message?.Contains("Cannot find source for binding")==true ||message?.Contains("System.Windows.Data Error")==true ? true: false; } }

Worked like a charm, thank you.
