NCache 4.6 - Online Documentation

Data Source Providers (Backing Source)

While working with data sources, it is important to transparently fetch the required data from the master data source if it is not available in the cache and vice versa. Read-Through and Write-Through are provided by NCache for this purpose. Now you can add multiple Read-Through and Write-Through providers with your applications.
If you are adding a custom object in NCache through backing source providers then you should place dlls local to the NCache service.
