DisableRuntimeMarshallingAttribute Class

Definition

Disables the built-in runtime managed/unmanaged marshalling subsystem for P/Invokes, Delegate types, and unmanaged function pointer invocations.

Remarks

The built-in marshalling subsystem has some behaviors that cannot be changed due to backward-compatibility requirements. This attribute allows disabling the built-in subsystem and instead uses the following rules for P/Invokes, Delegates, and unmanaged function pointer invocations:

  • All value types that do not contain reference type fields recursively (unmanaged in C#) are blittable.
  • Value types that recursively have any fields that have [StructLayout(LayoutKind.Auto)] are disallowed from interop.
  • All reference types are disallowed from usage in interop scenarios.
  • SetLastError support in P/Invokes is disabled.
  • varargs support is disabled.
  • LCIDConversionAttribute support is disabled.

Constructors

DisableRuntimeMarshallingAttribute()
