🟡 Changes recommended
The examples need valid generated API calls, and migration guidance must explain wrapper regeneration.

| ```csharp | ||
| // The generated ServiceCollection type did not implement IDisposable. | ||
| Service.ServiceCollection services = service.SelectAll(); |
|
|
||
| ## Recommended action | ||
|
|
||
| Dispose generated collection and enumerator wrappers when they are no longer needed, preferably with `using` or `using var`. |
|
|
||
| ## Previous behavior | ||
|
|
||
| The collection and enumerator types emitted by <xref:System.Management.ManagementClass.GetStronglyTypedClassCode%2A> did not implement <xref:System.IDisposable>. A generated collection could not be used in a `using` statement, and consumers could not deterministically release the WMI resources held by its wrapped <xref:System.Management.ManagementObjectCollection> or enumerator. |
