Remarks

A developer can access an object that implements the IPinnable interface without pinning it only through managed APIs. Pinning is required for access by unmanaged APIs.

Call this method to indicate that the IPinnable object cannot be moved by the garbage collector so that the address of the pinned object can be used.
