Installing .NET on Android

This runs .NET natively
not in a vm
not in a container
no need to have root access or jailbreaking your android
.NET runs natively on android in user space

Install Termux apk on android

pkg install proot
pkg install proot-distro

proot-distro allows to install linux which runs along with android os. This is not a vm so we get native performance.

proot-distro commands:

    proot-distro list - show the supported distributions and their status.
    proot-distro install - install a distribution.
    proot-distro login - start a root shell for the distribution.
    proot-distro remove - uninstall the distribution.
    proot-distro reset - reinstall the distribution.

Following linux flavours are supported:

1. Alpine Linux (edge)
2. Arch Linux / Arch Linux 32 / Arch Linux ARM
3. Debian (stable)
4. Fedora 35
5. Manjaro AArch64
6. OpenSUSE (Tumbleweed)
7. Ubuntu (22.04)
8. Void Linux

Following are the steps for Ubuntu

proot-distro install ubuntu
proot-distro login ubuntu  --termux-home 
su
apt install wget -y
apt install ssh -y
apt-get install -y net-tools

Manual installation of .NET: https://learn.microsoft.com/en-us/dotnet/core/install/linux-scripted-manual#scripted-install

wget https://dot.net/v1/dotnet-install.sh -O dotnet-install.sh

cd ~/.dotnet
echo 'export DOTNET_ROOT=$HOME/.dotnet' >> ~/.bashrc
echo 'export PATH=$PATH:$DOTNET_ROOT:$DOTNET_ROOT/tools' >> ~/.bashrc
source ~/.bashrc

Now the dotnet CLI can be used, more on this: https://learn.microsoft.com/en-us/dotnet/core/tools/dotnet
