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:
1. "Install" F#
```
nix-shell -p dotnet-sdk_7
```
2. Follow all the steps in [Get started with F# with command-line tools - .NET | Microsoft Learn](https://learn.microsoft.com/en-us/dotnet/fsharp/get-started/get-started-command-line). (No errors.)
3. Install `paket` following the [install guide](https://fsprojects.github.io/Paket/get-started.html#NET-Core-preferred).
4. Follow the [walkthrough](https://fsprojects.github.io/Paket/learn-how-to-use-paket.html#Walkthrough) on adding dependencies.
Specifically:
1. added `nuget FSharpPlus` to `paket.dependencies`
2. created the `src/App/paket.references` with the the line `FSharpPlus`
3. ran `dotnet paket install`
Once done, simply added `open FSharpPlus` to `src/App/Program.fs`, and ran `dotnet restore` followed by `dotnet build`, which blew up with
```
error FS0039: The namespace or module 'FSharpPlus' is not defined.
```
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/cli/cli.fsproj package "Giraffe.Htmx" --version "1.9.6"~~
dotnet build
```
and everything worked... So what is the point of using `paket` or `nuget` then?

How to automatically add package reference into project file after installing .NET package?
