Install .NET Core SDK in Manjaro Linux

export DOTNET_ROOT=/usr/share/dotnet
export MSBuildSDKsPath=$DOTNET_ROOT/sdk/$(${DOTNET_ROOT}/dotnet --version)/Sdks
export PATH=${PATH}:${DOTNET_ROOT}

dotnet --list-sdks

To use the extra tools, such as dotnet ef, you will want to add a line to your .bashrc file.

nano ~/.bashrc

And add the following at the end:

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

source ~/.bashrc
