xbuild on Ubuntu fails

[staspika]

Attempting to build using xbuild on Ubuntu results in the following error:

OBKDeviceAPI.cs(125,61): error CS0012: The type System.Configuration.ConfigurationSection' is defined in an assembly that is not referenced. Consider adding a reference to assembly System.Configuration, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'

Any ideas how to make it build successfully?

Try msbuild instead.

sudo apt install gnupg ca-certificates
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF
echo "deb https://download.mono-project.com/repo/ubuntu stable-bionic main" | sudo tee /etc/apt/sources.list.d/mono-official-stable.list
sudo apt update
sudo apt install mono-roslyn mono-complete mono-dbg msbuild
