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 package contains the mono system.data.linq library which implements linq to sql. linq to sql allows one to query relational databases using the language-integrated query (linq) extension of the c# programming language.
