IronPdfUnsupportedException

Thrown when attempting to use features not supported in the current environment or configuration. Common causes include platform limitations, missing dependencies, or deprecated functionality.

try {
    // Attempt operation that may not be supported:
    pdf.SignWithTimestamp(signature, timestampServer);
}
catch (IronPdfUnsupportedException ex) {
    // Handle unsupported feature gracefully:
    Console.WriteLine($"Feature not available: {ex.Message}");
    // Fall back to alternative:
    pdf.Sign(signature);  // Sign without timestamp
}

// Check platform before attempting:
if (RuntimeInformation.IsOSPlatform(OSPlatform.Linux)) {
    // Some features may not be available on Linux
    Console.WriteLine("Limited features on Linux");
}

Check documentation for platform-specific limitations

Consider fallback options for unsupported features
