ProjectCollection equivalent for Clickonce

Microsoft created ProjectCollection (BuildEngine on frameworks below 开发者_如何学编程4) to use MSBuild directly on code.

Is there any equivalent to publish applications through clickonce or do we have to call Mage.exe by command line?

AFAIK, you can use msbuild to build and publish the apps; mage is used to create the manifests required by ClickOnce. There is no change to this with .NET 4.
