HttpClientHandler.Dispose Method (Boolean)
Releases the unmanaged resources used by the HttpClientHandler and optionally disposes of the managed resources.
Assembly: System.Net.Http (in System.Net.Http.dll)
This method is called by the public Dispose() method and the Finalize method. Dispose() invokes the protected Dispose(Boolean) method with the disposing parameter set to true. Finalize invokes Dispose with disposing set to false.
When the disposing parameter is true, this method releases all resources held by any managed objects that this HttpClientHandler references. This method invokes the Dispose() method of each referenced object.
