When using `ExcludeFromCodeCoverage`, always provide a reason for the exclusion. This helps with code maintenance and is part of the documentation that helps other engineers understand why the code is excluded from coverage.

## Non-Compliant Code Examples{% #non-compliant-code-examples %}

```csharp
class MyClass {
    [ExcludeFromCodeCoverage]
    public void MyMethod()
    {
    }
}
```

## Compliant Code Examples{% #compliant-code-examples %}

```csharp
class MyClass {
    [ExcludeFromCodeCoverage(Justification = "Code used by some flaky test that will be removed soon")]
    public void MyMethod()
    {
    }
}
```
