+  ChangelogContent: |-
+    #### Breaking Changes
+    * **Default Sampler Changed** ([#54942](https://github.com/Azure/azure-sdk-for-net/pull/54942)): The default sampling behavior has been changed from
+    `ApplicationInsightsSampler` with 100% sampling (all traces sampled) to
+    `RateLimitedSampler` with 5.0 traces per second. This change significantly
+    reduces telemetry volume for high-traffic applications and provides better
+    cost optimization out of the box.
+    **Impact**: Applications with more than 5 requests per second will see fewer
+    traces exported by default.
+    **Migration**: To maintain the previous behavior (100% sampling), explicitly
+    configure the sampler:
+    ```csharp
+    // Option 1: Set SamplingRatio and clear TracesPerSecond
+    builder.Services.AddOpenTelemetry()
+    .UseAzureMonitorExporter(options =>
+    {
+    options.SamplingRatio = 1.0f;
+    options.TracesPerSecond = null;
+    });
+    // Option 2: Use environment variables
+    // OTEL_TRACES_SAMPLER=microsoft.fixed_percentage
+    // OTEL_TRACES_SAMPLER_ARG=1.0
+    ```
+
+    #### Bugs Fixed
+
+    * Fixed performance counter metrics not using configured resource attributes
+    (cloud_RoleName and cloud_RoleInstance), which previously showed
+    "unknown_service:appName" instead of the configured values.
+    ([#54944](https://github.com/Azure/azure-sdk-for-net/pull/54944))
