F# Support for Web Projects

In December of last year, I announced a few templates that made it easy to create pure-F# MVC 5 and Web API 2 projects in Visual Studio 2012 and 2013. In a parallel stream, the F# team was working closely with the F# community to improve the F# web development experience by adding features such as publish-to-web. It's exciting to see that this great work is now available as a Visual F# Tools Preview. You can read more about this at This, as well as the recent announcement regarding the acceptance of contributions to the Visual F# Tools, is a huge step forward in the evolution of web development with F#.

TypeScript in First-Class F# Web Projects

I was recently asked about how best to use TypeScript within a pure F# web project. Currently, there are two steps that are needed to make this happen. 

1. Add the TypeScript item template by downloading and installing the latest version of the F# Web Item Templates extension from

2. Modify your project file to allow the TypeScript files to compile to JavaScript when the project is compiled. To do this, you need to do the following:

- Edit your fsproj file. 

- Add the TypeScriptToolsVersion element and specify the appropriate TypeScript version that you have installed.

- Add 3 new commands to the BeforeBuild target.

- Save and re-open your project. You should now be good to go.

I plan to work on a solution to reduce the pain of step 2 in the near future, so stay tuned...
