Hi I want to add a starter project to my company's app store but do not know what I need to select as the Source File. Is it the projects .mpk file or do I need to zip up my whole project? I can't seem to find an answer in the documentation. Thanks in advance.
The AppStore expects .mpk files as source for both modules and projects.
For a project you can open the File menu and choose 'Export project package...' and follow the dialog. For a module, you can right click on the module you want to export and then choose 'Export module package...'.
