 ## Rule description
 
-When logging methods are called, their arguments are evaluated regardless of whether the logging level is enabled. This can result in expensive operations being executed even when the log message won't be written. For better performance, guard expensive logging calls with a check to <xref:Microsoft.Extensions.Logging.ILogger.IsEnabled%2A> or use the `LoggerMessage` pattern.
+When logging methods are called, their arguments are evaluated regardless of whether the logging level is enabled. This can result in expensive operations being executed even when the log message won't be written. For better performance, guard expensive logging calls with a check to <xref:Microsoft.Extensions.Logging.ILogger.IsEnabled%2A> or use source-generated logging with <xref:Microsoft.Extensions.Logging.LoggerMessageAttribute>.
 
 ## How to fix violations
 
 To fix a violation of this rule, use one of the following approaches:
 
 - Guard the logging call with a check to <xref:Microsoft.Extensions.Logging.ILogger.IsEnabled%2A>.
-- Use the `LoggerMessage` pattern with <xref:Microsoft.Extensions.Logging.LoggerMessageAttribute>.
+- Use source-generated logging with <xref:Microsoft.Extensions.Logging.LoggerMessageAttribute>.
 - Ensure expensive operations aren't performed in logging arguments unless necessary.
 
 ## Example
 
 The following code snippet shows violations of CA1873:
 
-```csharp
-using Microsoft.Extensions.Logging;
-
-class Example
-{
-    private readonly ILogger _logger;
-
-    public Example(ILogger<Example> logger)
-    {
-        _logger = logger;
-    }
-
-    public void ProcessData(int[] data)
-    {
-        // Violation: expensive operation in logging argument.
-        _logger.LogDebug($"Processing {string.Join(", ", data)} items");
-
-        // Violation: object creation in logging argument.
-        _logger.LogTrace("Data: {Data}", new { Count = data.Length, Items = data });
-    }
-}
-```
-
-```vb
-Imports Microsoft.Extensions.Logging
-
-Class Example
-    Private ReadOnly _logger As ILogger
-
-    Public Sub New(logger As ILogger(Of Example))
-        _logger = logger
-    End Sub
-
-    Public Sub ProcessData(data As Integer())
-        ' Violation: expensive operation in logging argument.
-        _logger.LogDebug($"Processing {String.Join(", ", data)} items")
-
-        ' Violation: object creation in logging argument.
-        _logger.LogTrace("Data: {Data}", New With {.Count = data.Length, .Items = data})
-    End Sub
-End Class
