<summary>Release notes</summary>

_Sourced from [Azure.Monitor.OpenTelemetry.AspNetCore's
releases](https://github.com/Azure/azure-sdk-for-net/releases)._

## 1.5.0

## 1.5.0 (2026-04-30)

### Features Added

* Add ability to specify EnableStandardMetrics and
EnablePerformanceCounters
  ([#​56438](Azure/azure-sdk-for-net#56438))

### Breaking Changes

* **Default Sampler Changed**: 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()
      .UseAzureMonitor(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 an issue where Azure Container Apps instances were showing VM
instance GUIDs
  instead of replica names in the Role Instance field.
