Running ASP.NET Core exe from MacOS Finder produces error: "The WebRootPath was not found"

Question

I have published an ASP.NET Core app for MacOS. If I run it from the terminal (./BlazorApp1) it works fine. But if I try to run the exe from Finder I always get this error message:

The WebRootPath was not found: /Users/scott/wwwroot. Static files may be unavailable

Is it possible to run the exe produced from Finder?

You can fix the issue by using below settings in MacOS.

// For OSX
if (System.Runtime.InteropServices.RuntimeInformation.IsOSPlatform(System.Runtime.InteropServices.OSPlatform.OSX))
{
    app.UseStaticFiles(new StaticFileOptions
    { 
        FileProvider = new PhysicalFileProvider(Path.Combine(System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetEntryAssembly().Location), "wwwroot")), RequestPath = "" });
    }
// For Windows
else {
    app.UseStaticFiles();
}
