Hi Namita,
For each Class in the Module you want to enable synchronization for, you need to configure the type definition by enabling content staging. The documentation describes how to do this.
But essentially you need to copy the Code of the class into your project and then you can configure it by adding:
SynchronizationSettings =
{
LogSynchronization = SynchronizationTypeEnum.LogSynchronization,
ObjectTreeLocations = new List<ObjectTreeLocation>()
{
// Adds the custom class into a new category in the Global objects section of the staging tree
new ObjectTreeLocation(GLOBAL, "Custom")
},
},
