like it gave to me solution input into project's properties this

I build and publish as a single file app.

You have to set a few different things for MSBuild to actually produce a single file executable. Here is a link to the most recent Workflow run with the build artifact.

• .csprojj
• Directory.Build.props
• Directory.Build.targets

thanks your reply and I will do your solution. Actually , I resolved that problem before through try ~ catch.
I debugged and found basePath became null when execute exe file not in the visual studio's ctrl+f5.
nomally in the vs when execute(ctrl+f5), That path is that my program path(Dbug / Release Mode path) .
but I execute exe file, basePath is null. so I just add try catch since basePath is null so can't go next logic.
but Im wondering basePath is important part for starting app. but why basePath is null, is continue with logic and no problem?
Im just add try ~ catch. and not set basePath, it is status just 'null' from exceute program to exit program.

private static readonly IHost _host = Host.CreateDefaultBuilder() .ConfigureAppConfiguration(c => { var basePath = Path.GetDirectoryName(AppContext.BaseDirectory) ?? throw new DirectoryNotFoundException( "Unable to find the base directory of the application." ); _ = c.SetBasePath(basePath); }) .ConfigureServices( (context, services) => { // App Host
.....
}

Ctrl + F5 is start without debugging.

F5 is start debugging.

The same reproduction from the latest stable version of the VS2022 community by expanding the newly created Compact Navigation template.
The problem is pinpointed to a null path for _host in App.xaml.cs of the template code

Non-null object, but empty string information

Path.GetDirectoryName(AppDomain.CurrentDomain.BaseDirectory)! or Path.GetDirectoryName(AppContext.BaseDirectory)! should be used

[MNDIA]

Expect the template to be fixed soon

[syntax-tm]

Single file deployments cannot use the Location property (source). You can use AppContext.BaseDirectory instead.
