This handle type represents an opaque handle, meaning you cannot resolve the address of the pinned object through the handle.

This enumeration member is useful when an unmanaged client holds the only reference, which is undetectable from the garbage collector, to a managed object.

This handle type is similar to , but allows the address of the pinned object to be taken. This prevents the garbage collector from moving the object and hence undermines the efficiency of the garbage collector. Use the method to free the allocated handle as soon as possible.

This handle type is used to track an object, but allow it to be collected. When an object is collected, the contents of the are zeroed. Weak references are zeroed before the finalizer runs, so even if the finalizer resurrects the object, the Weak reference is still zeroed.
