Done!
- Installation complete!
- What next?
- Let's write some C♯
Let's Compile some C♯!
Package Management
- Most Linux distributions use a package manager
- Everything is a package - from your kernel to the software that you use
- Debian-based distributions use
apt
Mono
- Mono is the .NET runtime on Linux
- Mono isn't available in the default
apt
repositories on Ubuntu - ...so we need to add a new apt repository!
- https://www.mono-project.com/download/stable/
Installation
- We have the
apt
repository - Now we can install
Mono
sudo apt install mono-devel
Usage
- The Linux terminal is similar to the Windows command prompt
- Download a Visual Studio solution now if possible
- Use a text editor to write a quick program otherwise
Usage (cont.)
- We can use
csc
andmsbuild
to compile just like we do on Windows csc MyFile.cs
msbuild
Monodevelop
What's Monodevelop?
- Writing C♯ code in a text editor is old-school
- Like Visual Studio, but on Linux
- Actually the base of Visual Studio for Mac
Installing
- Same prodecure as with Mono
- Challenge: Can you install Monodevelop using what you've learnt?
- https://www.monodevelop.com/download/
