Default Marshaling Behavior
Interop marshaling operates on rules that dictate how data associated with method parameters behaves as it passes between managed and unmanaged memory. These built-in rules control such marshaling activities as data type transformations, whether a callee can change data passed to it and return those changes to the caller, and under which circumstances the marshaler provides performance optimizations.
This section identifies the default behavioral characteristics of the interop marshaling service. It presents detailed information on marshaling arrays, Boolean types, char types, delegates, classes, objects, strings, and structures.

| Marshaling of generic types is not supported. For more information see, Interoperating Using Generic Types. |
