I want to build Sitecore packages programmatically. Can you tell me what class I can use for this? Or tell me about any manuals about this?
In many manuals I can read only about create packages from Package Designer, but I don't need this...
In addition you should also take a look at Sitecore Courier and Unicorn.
You can try to use Continous deployment with Powershell Console.
You can also check Sitecore.Install.PackageGenerator
class in the Sitecore.Kernel
.
