Run sideloaded WPF Core 3.0 app from command line

Question

I've run into a problem while publishing a WPF Core 3.0 app. I created a Windows Application Packaging Project in my solution and then published the WPF app as sideloaded. It was published correctly and I can run it without any problems. However, now I need to start the sideloaded WPF app from another application (WinForms) programmatically with line arguments. Is there any way to do that? Thanks

You can define an app execution alias extension for your packaged app. Please refer to the docs and this blog post for more information.

<Package
  xmlns:uap3="http://schemas.microsoft.com/appx/manifest/uap/windows10/3"
  IgnorableNamespaces="uap3">
    <Applications>
        <Application>
            <Extensions>
                <uap3:Extension
                Category="windows.appExecutionAlias"
                Executable="exes\launcher.exe"
                EntryPoint="Windows.FullTrustApplication">
                    <uap3:AppExecutionAlias>
                        <desktop:ExecutionAlias Alias="Contoso.exe" />
                    </uap3:AppExecutionAlias>
                </uap3:Extension>
            </Extensions>
        </Application>
    </Applications>
</Package>
