DotNetLoadObject Function

Action

Loads a .NET Assembly and creates an instance of a .NET type. A handle to this created object will be returned. When creating the object, the default constructor will be called. If you want to call a constructor that takes parameters you have to set these parameters with the DotNetSetXX functions prior to the call to DotNetLoadObject.
