How to automatically add package reference into project file after installing .NET package?
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). 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
paketfollowing the install guide. -
Follow the walkthrough on adding dependencies.
Specifically:
- added
nuget FSharpPlustopaket.dependencies - created the
src/App/paket.referenceswith the the lineFSharpPlus - ran
dotnet paket install
Once done, simply added
open FSharpPlustosrc/App/Program.fs, and randotnet restorefollowed 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.
update: Alright, I'm officially clueless. 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?

You don't have to do that. Paket isn't really user-friendly so you may think you have to add reference to a package twice.
Paket is a dependency manager for .net projects but it's not the most used one.
Using just dotnet cli (or edit .fsproj manually) is more than enough for most cases. So best to avoid Paket until you get some confidence in dotnet world.
