I absolutely love .NET development. I also love working in Linux. So the .NET Core project was a real blessing for me, and now .NET Core has become .NET 6. It’s very mature, stable, and empowers you to build endless ideas. If you want to run or develop .NET applications in Manjaro Linux, you may notice no instructions for it. So, I decided to document my setup.

We’ll cover running .NET applications and building .NET applications in Manjaro.

If you want to run .NET applications:

If you just want to run .NET applications on Manjaro, it’s pretty easy. Here’s how you get the latest runtime. You’ll need to download the dotnet-install.sh file and make a change to a file.

At a command prompt, get the script:

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

and make it executable:

chmod +x dotnet-install.sh

Then, you can run it and grab the latest version of the .NET runtime.

sudo ./dotnet-install.sh --install-dir /usr/share/dotnet -channel Current -version latest

It should look something like this:

Great! Now you’re up and running.

Then, you’ll need to create /etc/profile.d/dotnet.sh and add the following:

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

Now, you’re ready to go. Log out and log back in.

Run

dotnet --list-sdks

And it should look something like this:

And we can see our SDK. Now you can run .NET applications on your Manjaro machine.

If you want to develop .NET applications

If you want to develop applications, the best way is to use the Arch repositories and install the .NET Core SDK

You can install this with Pacman:

sudo pacman -S dotnet-sdk

if you want the ASP.Net Runtime also, you can run this:

aspnet-runtime

You will also need to run this:

Create /etc/profile.d/dotnet.sh and add the following:

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

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

open it up:

vim ~/.bashrc

And add the following at the end:

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

Now reload the file:

source ~/.bashrc

And you’re ready to go. Let’s test it out!

Create a new application

Let’s create a new Blazor application to test the .NET SDK on our Manjaro machine. Type in the following:

dotnet new blazorserver -o BlazorTest --no-https

This will create a new Blazor application. You should see something like this:

Let’s run it:

cd BlazorTest
dotnet watch

And here it is!

Using dotnet watch you can run your application and use hot reload. This way you can make changes in real time.
