I'm trying to package my program that I have made in Visual Studio. I can't seem to package it into an Appx file using the recommended settings in Visual Studio. I am trying to add it to the windows store and I am wondering whether there is any other ways to change a .exe file into a file that is suitable for the windows store.
Thanks for any help that you have, FBR Studios
Yes, you can repackage your .exe as an .appx package. Windows 10 has the infrastructure for it called the Desktop Bridge. You can repackage your installer either with Desktop App Converter, a free tool from Microsoft or with any of many third-party tools that repackage .exe into various formats, including .appx.
Microsoft website has a nice page about the Desktop Bridge technology, Desktop App Converter and about and third-party tools - I suggest checking it out: https://learn.microsoft.com/en-us/windows/uwp/porting/desktop-to-uwp-root
