How to install dotnet (NET Core) 3.0 Preview6?

mblataric

Hi,
I am trying to jump on linux wagon and Solus really caught my eye, but I am having some issues in setting it up as my development environment.
I need dotnet preview version (3.0) which is not available for installation in snap, so I have to do it manually.
I managed to install Visual Studio Code and NET Core 3 Preview6, but I am getting an error when running dotnet restore:
Unable to load the service index for source https://api.nuget.org/v3/index.json.
This has been discussed in Jamie Phillips blog, but it seems this no longer applies because liblttng-ust package is no longer available in eopkg (and neither in snap).

Any idea how to get around it?
Thanks.

You can download the tarball for .net core 3.1 here.

The recommendation on the page is to install it in your home directory but I install it into /opt:

sudo mkdir -p /opt/dotnet && sudo tar xf dotnet-sdk-*.tar.gz -C /opt/dotnet

then add the following to your _/.bashrc

export DOTNET_ROOT=/opt/dotnet
export PATH=$PATH:/opt/dotnet

If you are running VS Code you should make a symlink otherwise omnisharp will STB
sudo ln -s /opt/dotnet/dotnet /usr/bin/dotnet
