mono-complete - 5.18.0.240+dfsg-3+deb10u1 main

Mono is a platform for running and developing applications based on the
ECMA/ISO Standards. Mono is an open source effort led by Xamarin.
Mono provides a complete CLR (Common Language Runtime) including compiler and
runtime, which can produce and execute CIL (Common Intermediate Language)
bytecode (aka assemblies), and a class library.
.
This is a metapackage and pulls in the Mono runtime, development tools and
all libraries.
.
Install this package if you want to run software for Mono or Microsoft .NET
which you are not installing from a Debian package.
.
For packagers: This package is not to be used as dependency for packages!
You should build-depend on cli-common-dev and the needed libraries instead.
