To enable multiple build configurations in a single deployment
- In the project’s properties page, set the Isolate Configuration property to Yes.

- Give a unique name to each configuration.

- Add application elements that correspond to each of the configurations in the project to Package.appxmanifest, which is the default manifest file.
[!NOTE] You can specify different visual elements if you want the configurations to appear differently in the launcher.
- Add the
<Extensions>node to the manifest if your project contains a reference to a WinRT project and you would like to deploy multiple configurations of the WinRT project.
<Extensions> configured for two WinRT projects.
