ASP.NET MVC 4 includes many new features including, but not limited to:
- New Web API support built in
- New project templates such as the mobile project template.
- Support for Mobile apps
- Support for Recipes (similar to, but not quite, like recipes in the Orchard CMS)
- Support for Async methods (think new async features)
Be sure to check out both. I’ll be posting more on it later on.
