OK... you've heard the Erlang success stories, you know the sweet spots, and you're convinced that Erlang is for you. Where does that leave you as a C# developer? In a pretty good spot actually. A team of C# and Erlang developers is a force to be reckoned with because Erlang and .NET are complements--each is lousy at what the other is exceptional at. Realizing this can save you and your company a lot of time, money and headaches. Many C# developers write both JavaScript and SQL scripts; adding Erlang to the mix should be just as natural. So how is it done? What are the best interop strategies? What are the development tools? Can it all be done on Windows? How about unit testing and deployment? What are the risks? How can they be avoided?

Would you like to build massively parallel, distributed, fault-tolerant, cross-platform, easily maintainable systems with less code and look cool doing it? If so, the opensource programming language Erlang has some real sweet spots for you. If you're unfamiliar with Erlang you may be surprised to learn how battle tested it is: Facebook's chat backend, CouchDB, RabbitMQ, GitHub's backend and Amazon's SimpleDB are all written in Erlang, and every phone call you make is likely helped along by some Erlang somewhere. So how does a functional programming language with Prolog and telecom roots solve so many of the big problems that Enterprisey languages famously stink at? What's so darn special about Erlang? What are the pieces and the tools? What does it look like? How do I (as a C# developer) even get started with Erlang?
Three anti-hero technologies (Microsoft's new Windows 8 Metro tablets, the Command-Query Responsibility Separation architectural pattern, and the opensource functional programming language Erlang) snap together to form a delightful, maintainable and scalable system. It's not a mainstream or obvious choice, but I'll show you in an opensource end-to-end application how they fit. This will be my technology stack of choice for years to come, and I look forward to showing you why.
