Invoking an Object Service
Volt MX provides you with programmatic access to backend data. Access is gained in two steps:
- Acquire a current instance of your object service.
- Use the object service instance together with data objects to communicate as needed with your backend.
To know more about how to acquire a current instance of your object service, refer to Creating an ObjectService Object documentation.
To know more about the methods that act on the Volt MX Foundry endpoint directly, refer to ObjectService Class documentation.
To know more about the usage of the data transfer objects, refer to DataObject Class documentation.
Note: The .NET SDK does not support Offline Object Services.
