StandardOleMarshalObject Class

Replaces the standard common language runtime (CLR) free-threaded marshaler with the standard OLE STA marshaler.

Namespace:  System.Runtime.InteropServices
Assembly:  System (in System.dll)

public class StandardOleMarshalObject : MarshalByRefObject

The StandardOleMarshalObject class prevents calls made into a hosting object by OLE from entering threads other than the UI thread.

You should derive your class from the StandardOleMarshalObject class to gain this functionality.


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