Using Launcher in .NET MAUI to open a file opens the "share" menu on a Mac

[johnandrewoehler]

Description

When using the example provided in the documentationa "share" dialog opens up instead of the text file with default viewer (or open file extension dialog).

It does this with the exact code from the docs:

string popoverTitle = "Read text file";
string name = "File.txt";
string file = System.IO.Path.Combine(FileSystem.CacheDirectory, name);

System.IO.File.WriteAllText(file, "Hello World");

await Launcher.Default.OpenAsync(new OpenFileRequest(popoverTitle, new ReadOnlyFile(file)));

This is very similar to this issue for Xamarin.

Steps to Reproduce

1. Clone the sample repo.
2. Run it on a Mac.
3. Click on the "Click me"
4. Observe that it brings up the 'share' extensions menu and not the file or a menu to select which app to open it with (such as Previewer, Chrome, etc.)

Any update on this please? I'm getting the same issue when opening a simple JPG or PDF file. Still showing the same edit action window instead of opening the default app for the specific file. I already passed the MimeType.

Happning in iOS 17.2

FileInfo fi = new FileInfo(path);
var mimeType = MimeTypeHelper.GetMimeTypeFromExtension(fi.Extension);
return await Launcher.Default.OpenAsync(new OpenFileRequest
{
    File = new ReadOnlyFile(path, mimeType)
});
