How to have multiple SDKs/Runtimes at the same time ?

[kedare]

Hello.

I was trying to compile identity server ( https://github.com/DuendeSoftware/IdentityServer ) but it requires both SDK 5.0 and 3.1.0 to be available, I installed them both with asdf and set 5.0 as the global one but I am getting the following error

bash build.sh 
Tool 'signclient' (version '1.2.17') was restored. Available commands: SignClient
Tool 'dotnet-ef' (version '3.1.0') was restored. Available commands: dotnet-ef

Restore was successful.

It was not possible to find any compatible framework version
The framework 'Microsoft.NETCore.App', version '3.1.0' was not found.
  - The following frameworks were found:
      5.0.0 at [/home/kedare/.asdf/installs/dotnet-core/5.0.100/shared/Microsoft.NETCore.App]

You can resolve the problem by installing the specified framework and/or SDK.

The specified framework can be found at:
  - https://aka.ms/dotnet-core-applaunch?framework=Microsoft.NETCore.App&framework_version=3.1.0&arch=x64&rid=linuxmint.20-x6

A few info:

dotnet --list-sdks
5.0.100 [/home/kedare/.asdf/installs/dotnet-core/5.0.100/sdk]

dotnet --list-runtimes
Microsoft.AspNetCore.App 5.0.0 [/home/kedare/.asdf/installs/dotnet-core/5.0.100/shared/Microsoft.AspNetCore.App]
Microsoft.NETCore.App 5.0.0 [/home/kedare/.asdf/installs/dotnet-core/5.0.100/shared/Microsoft.NETCore.App]

asdf list dotnet-core
  3.1.404
  5.0.100

How can I fix that ?

Thanks

Hmm, my guess is that you just need the 3.1 sdk. You can set it to local with:

asdf local dotnet-core 3.1.404

or globally with:

asdf global dotnet-core 3.1.404

You can have have multiple sdk's using the local feature of asdf.

I'm running into a similar issue trying to install FsAutoComplete for neovim LSP.

projects/fsharp/demo via .NET v5.0.400 🎯 netcoreapp3.1
➜ asdf local dotnet-core 3.1.412
projects/fsharp/demo via .NET v3.1.412 🎯 netcoreapp3.1
➜ dotnet tool install --global fsautocomplete
error NU1202: Package fsautocomplete 0.47.1 is not compatible with netcoreapp3.1 (.NETCoreApp,Version=v3
.1) / any. Package fsautocomplete 0.47.1 supports: net5.0 (.NETCoreApp,Version=v5.0) / any
The tool package could not be restored.
Tool 'fsautocomplete' failed to install. This failure may have been caused by:

* You are attempting to install a preview release and did not use the --version option to specify the ve
rsion.
* A package by this name was found, but it was not a .NET Core tool.
* The required NuGet feed cannot be accessed, perhaps because of an Internet connection problem.
* You mistyped the name of the tool.

For more reasons, including package naming enforcement, visit https://aka.ms/failure-installing-tool

➜ asdf local dotnet-core 5.0.400

➜ dotnet tool install --global fsautocomplete
Tools directory '/home/jesse/.dotnet/tools' is not currently on the PATH environment variable.
If you are using bash, you can add it to your profile by running the following command:

cat << \EOF >> ~/.bash_profile
# Add .NET Core SDK tools
export PATH="$PATH:/home/jesse/.dotnet/tools"
EOF

You can add it to the current session by running the following command:

export PATH="$PATH:/home/jesse/.dotnet/tools"

You can invoke the tool using the following command: dotnet-fsautocomplete
Tool 'fsautocomplete' (version '0.47.1') was successfully installed.

I then run into fsprojects/fantomas#412

Should dotnet and dotnet-core be two different asdf plugins so we can have access to both?
