✅ which .net version should I be starting with?

enrico11011 · 2025-04-09T01:36:48.673Z

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

dotnet run

dotnet run

it gives me this

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

new

so I got the demo to run by doing

dotnet run --roll-forward LatestMajor

dotnet run --roll-forward LatestMajor

dotnet run --roll-forward LatestMajor

dotnet run --roll-forward LatestMajor

i'm more interested in seeing if I did something wrong in the setup

enrico11011OP•4/9/25, 3:31 AM

dotnet --version

dotnet --version

dotnet --version

dotnet --version shows 9.0.202

yeah change that

    <TargetFramework>net6.0</TargetFramework>

<TargetFramework>net6.0</TargetFramework>

    <TargetFramework>net6.0</TargetFramework>

<TargetFramework>net6.0</TargetFramework>
to

    <TargetFramework>net9.0</TargetFramework>

<TargetFramework>net9.0</TargetFramework>

    <TargetFramework>net9.0</TargetFramework>

<TargetFramework>net9.0</TargetFramework>

E

enrico11011OP•4/9/25, 6:39 AM

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?

What was the "original command" you refer to?

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

TeBeCo•4/9/25, 8:12 AM

TeBeCo•4/9/25, 8:12 AM

and their new lib

T

TeBeCo•4/9/25, 8:12 AM

open an issue on their repo and ask if there's limitation

C

canton7•4/9/25, 8:16 AM

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

T

TeBeCo•4/9/25, 9:12 AM

gotta ask them if the readme / roadmap is up to date

T

TeBeCo•4/9/25, 9:12 AM

because net6 is dead, net10 is around the corner (6month)
