Compilers use the NativeCppClassAttribute attribute when building assemblies to indicate that a type is an unmanaged type defined in C or C++. This attribute is used later to correctly handle the unmanaged type when it is imported during interop.


Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
