Visual Studio has the clear message about what's going on: there is Note class in both namespaces - Melanchall.DryWetMidi.Interaction and Melanchall.DryWetMidi.MusicTheory. If you search the error (c# is an ambiguous reference between), you'll find that it's a common situation in .NET world and there are several ways to resolve it.

In your short example you can just write:

IEnumerable<Melanchall.DryWetMidi.Interaction.Note> notes = file.GetNotes();

or

var notes = file.GetNotes();

or

using InteractionNote = Melanchall.DryWetMidi.Interaction.Note;

...

IEnumerable<InteractionNote> notes = file.GetNotes();

Thank s a loot for your support. I am simply new in C# and visual studio world.

I tried this part of code

var notes = file.GetNotes();

working well

but when I put this

using InteractionNote = Melanchall.DryWetMidi.Interaction.Note;
..
IEnumerable notes = file.GetNotes();

and this

IEnumerable<Melanchall.DryWetMidi.Interaction.Note> notes = file.GetNotes();

In visual studio code terminal return
can not find file. in file.GetNotes();

@2311627BorisBacic Show please the full content of the file.

Of course the file variable cannot be found, because you use midiFile variable. This works great:

var notes = midiFile.GetNotes();
IEnumerable<Melanchall.DryWetMidi.Interaction.Note> notes2 = midiFile.GetNotes();
IEnumerable<InteractionNote> notes3 = midiFile.GetNotes();

Please be more attentive. I'm not a C# teacher :-)

Thank s lot I am started before one month in C# first with visual studio 2022 now I change to Visual Studio Code I am moving but moving very slow. I want to do something with mid file and I found your GitHub and I started.
