I created Windows Phone 8.1 Silverlight app, and I can't to upload it into WP store. I want to use Create App Packages tool in Visual Studio 2013 Professional, but it's impossible for Silverlight apps. I read many guides on dev.windows.com. It's necessary to upload only .appx, .appxbundle or .appxupload files, but I have .xap file only in Bin\ARM\Release folder. May anyone help me?
