Just getting into F#, finally figured out how to add .NET packages to projects, but the way I managed to get it to work doesn’t make sense. Once the package is installed (either with nuget
or paket
), I have to manually add a reference to the project file (either by editing it directly or with dotnet add package
(https://learn.microsoft.com/en-us/dotnet/core/tools/dotnet-add-package
). This extra step is usually automated with other languages, so I presume that I’m doing something wrong.
These are the steps I did on a Mac M1:
-
“Install” F#
nix-shell -p dotnet-sdk_7
-
Follow all the steps in Get started with F# with command-line tools - .NET | Microsoft Learn. (No errors.)
-
Install
paket
following the install guide (https://fsprojects.github.io/Paket/get-started.html#NET-Core-preferred
). -
Follow the walkthrough (
https://fsprojects.github.io/Paket/learn-how-to-use-paket.html#Walkthrough
) on adding dependencies.Specifically:
- added
nuget FSharpPlus
topaket.dependencies
- created the
src/App/paket.references
with the the lineFSharpPlus
- ran
dotnet paket install
Once done, simply added
open FSharpPlus
tosrc/App/Program.fs
, and randotnet restore
followed bydotnet build
, which blew up witherror FS0039: The namespace or module 'FSharpPlus' is not defined.
- added
The fix was simple enough,
dotnet add src/App/App.fsproj package "FSharpPlus" --version "1.5.0"
but it’s hard for me to believe that one has to add these references manually for each package.
After all this, just out of curiosity, I added open Giraffe.Htmx
to src/App/Program.fs
, then ran
dotnet add src/App/App.fsproj package "Giraffe.Htmx" --version "1.9.6"
dotnet build
and everything worked… So what is the point of using paket
or nuget
then?
(The thread What benefits do FAKE and PAKET provide over traditional ways? explains the benefits quite well, and I guess that my woes are stemming from doing this on a Mac and/or using Nix.)
