There is a new F#/C# ASP.NET MVC 3 template now available on Visual Studio Gallery.
This template requires the ASP.NET MVC 3 Tools Refresh to be installed on the target machine and it provides functionality slightly similar to that which the Tools Refresh adds for C#/VB. Information on installing the ASP.NET MVC 3 Tools Refresh can be found at http://www.asp.net/mvc/mvc3.
With this project template, you will be able to create an empty ASP.NET MVC 3 Web Application. During the creation process, you will see a screen similar to the following with options that allow selection of ASPX or Razor view engine. Additionally, you can optionally choose to include a project which can be used to contain unit tests.
As usual, you can find the full source on my GitHub. Note: This template is an enhanced version of a template that is described in the MSDN Magazine article entitled "Authoring an F#/C# VSIX Project Template". I will be posting something about this article very soon.
