Here are two code issues of the warning type that might be helpful in detecting objects of a class that have not undisposed. Such objects may lead to temporary unmanaged resource leaks.
The IDisposable Pattern is used to release and close unmanaged resources such as files, streams, and handles as well as references to managed objects that use unmanaged resources, held by an instance of the class. For classes that require a resource cleanup, we recommended following the IDisposable pattern, which provides a standard and unambiguous pattern. The pattern has been designed to ensure reliable, predictable cleanup, and to prevent temporary resource leaks.
