Create a valid MSIX deployment project with auto-update for .NET Core WPF sample app

*Goal* Given a sample WPF .NET Core 3.1 solution with a single project, add a packaging project to the solution that enables publishing of the app as an MSIX package with auto-update option. The project should be conducted with Visual Studio Community 2019. The resulting application should be compatible with Windows 10. *Input* WPF .NET Core 3.1 sample application (see attached .zip file) This application includes several points that could make MSIX packaging non trivial: - Reference to a NuGet package, - DLL import of `[login to view URL]`, - Use of "embedded resource in output assembly" option for a sample file, - Use of "Copy to output folder" option for a sample file Make sure the app runs correctly before you start working on it. See attached screenshot of running application. *Expected delivery* - WPF .NET Core 3.1 sample application which is ready for MSIX publishing into a local publish folder. - Command line to publish/deploy the project from the command line. *Test procedure to review delivery* When I receive your delivery, I will: - run the provided command line in the solution folder, - upload the published folder to an FTP server, - install the application on a test computer using the uploaded files, - check that the application runs correctly on the test computer, - make a change in the source code and upload a new published version, - verify that the application updates on the test computer.
