A blog post from Mindscape about the development experience of creating the Web Workbench product for Sass, Less and CoffeeScript in Visual Studio 2010. Like most .NET projects, it contains a fair chunk of C#. But quite a bit of the core is written in F#, and it also invokes a large amount of external Ruby and JavaScript code. While using all these languages definitely made it far easier to develop the product, it did also throw up a few challenges and surprises. This post looks at those challenges and surprises.
