Installing dotnet dependency

1. Download and install the .NET Core SDK for your platform (tested with .NET 6). For me this looked like the following:

   $ cd ~/Downloads/
   $ wget https://dot.net/v1/dotnet-install.sh -O dotnet-install.sh
   $ chmod +x ./dotnet-install.sh
   $ ./dotnet-install.sh
   dotnet-install: Attempting to download using aka.ms link https://dotnetcli.azureedge.net/dotnet/Sdk/6.0.415/dotnet-sdk-6.0.415-linux-x64.tar.gz
   dotnet-install: Remote file https://dotnetcli.azureedge.net/dotnet/Sdk/6.0.415/dotnet-sdk-6.0.415-linux-x64.tar.gz size is 186298830 bytes.
   dotnet-install: Extracting zip from https://dotnetcli.azureedge.net/dotnet/Sdk/6.0.415/dotnet-sdk-6.0.415-linux-x64.tar.gz
   dotnet-install: Downloaded file size is 186298830 bytes.
   dotnet-install: The remote and local file sizes are equal.
   dotnet-install: Installed version is 6.0.415
   dotnet-install: Adding to current process PATH: `/home/eric/.dotnet`. Note: This change will be visible only when sourcing script.
   dotnet-install: Note that the script does not resolve dependencies during installation.
   dotnet-install: To check the list of dependencies, go to https://learn.microsoft.com/dotnet/core/install, select your operating system and check the "Dependencies" section.
   dotnet-install: Installation finished successfully.

2. Update your $PATH environment variable so you can access dotnet from the CLI: .bashrc

   # For .NET dotnet, C# (csharp)
   # https://learn.microsoft.com/en-us/dotnet/core/install/linux-scripted-manual#set-environment-variables-system-wide
   export DOTNET_ROOT=~/.dotnet
   # export MSBuildSDKsPath=$DOTNET_ROOT/sdk/$(${DOTNET_ROOT}/dotnet --version)/Sdks
   export PATH=$PATH:$DOTNET_ROOT:$DOTNET_ROOT/tools
