  1. Research Languages on the .NET PlatformNick Benton Microsoft Research,Cambridge UK

  2. The Programming Language Landscape • C, C++, Visual Basic, Java, JScript, Perl, Cobol,... account for most commercial and industrial programming • but occupy only part of the space of programming language designs: • Domain-specific • Graphics • Music • Text-processing • Database Queries • Functional • Logic • Constraint • Concurrent • Component • Distributed

  3. The Problem (1) • For programming language researchers • Lots of work to implement a compiler for a new programming language. Much of it often not very specific to the language in question • garbage collection • threading • linking • development environment • backend optimizations • And if you want to be able to do anything in the new language, you have to implement a rich collection of libraries as well

  4. The Problem (2) • For developers • Libraries & interlanguage working features in research compilers are never good enough. Gluing new code to old often involves • autogenerated stubs • lowest common denominator data representations • hairy make scripts • so might just as well write the whole thing in C++ • And the development environments are usually pretty feeble too

  5. The Opportunity • The .NET Common Language Runtime provides a rich set of services to compiler writers • So it's much easier to get a working system with good performance • Sharing a sophisticated type system, memory manager, loader, etc. makes high-level interlanguage working easy • So you can access useful libraries and application components written in other languages straight away

  6. The Project • Microsoft has been working with leading programming language researchers from around the world, with the aim of • Getting their favourite languages to target the .NET platform • Demonstrating interlanguage working • Providing early feedback
