How does garbage collection work in C# and VB.NET for data returned from COM
object? For example, a COM object written in C++ returns a SAFEARRAY to C#
or VB.NET, will this SAFEARRAY (mapped to type in C# or VB.NET) be garbage

COM method invocation, will this...

Any and all:
Is there an efficient way to pass a large array from .NET to COM? Can
references (or pointer) be passed from COM to NET and NET to COM without the
object it refers to being copied?
