✅ which .net version should I be starting with?

i downloaded the latest version from the dotnet website, 9.0, and attempted to use this -> https://github.com/gui-cs/Terminal.Gui to build out a simple console app with a TUI, but I got an error saying that i need to be on .net 6, which is marked as end-of-support. is it fine to stick with 9.0, or should I roll back to 8.0? its not terribly important that I be able to use Terminal.Gui, I just don't want to be locked out of using other libraries because the version of .net i'm using is too new.

where are you seeing that error? the library is supported on .net 9 just fine

so i've followed the instructions on the github and when I try to dotnet run it gives me this

wasabi•2w ago

That sounds like YOU built a .NET 6 app.

what? i don't see how I could've done that, unless i was supposed to pass some argument into new so I got the demo to run by doing dotnet run --roll-forward LatestMajor i'm more interested in seeing if I did something wrong in the setup dotnet --version shows 9.0.202

@enrico11011 share your csproj and the output of dotnet --info.

yeah that seems to have done it. i'm guessing its a bug that the original command puts out 6.0 as opposed to 9.0? or is this sort of thing normal in the C# world?

canton7•2w ago

What was the "original command" you refer to?

ero•2w ago

dotnet new tui

canton7•2w ago

Yeah, looks like v1 of the template project uses .NET 6: https://github.com/gui-cs/Terminal.Gui.templates/blob/v1.0.3/templates/basic/MyGuiCsProject.csproj#L5

Yeah, the readme says that V2 is in alpha but you can use it if you want, while V1 is stable and receiving maintenance updates
