Thus, their usage is optional (but required when compiling said libraries yourself).\n\n * A C# 5 compiler\n   * csc or [Roslyn](https://github.com/dotnet/roslyn) on Windows\n   * [mcs](http://www.mono-project.com/docs/about-mono/languages/csharp/) on Mono\n * A somewhat recent D# compiler\n   * [dsc](https://github.com/jonathanvdc/Flame/releases)\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjonathanvdc%2Fdfasm","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fjonathanvdc%2Fdfasm","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjonathanvdc%2Fdfasm/lists"}
