Run webapi without installing .net4.5

Question

I have a website running aspx pages, under asp.net4.0. I also have some DevExpress controls, that I purchased 4 years ago. I now want to add an API to the web application, however I understand that needs .net4.5 to be running. The DevExpress controls don't work under 4.5 - so I would need to renew them at considerable cost. - it possible, after installing .net4.5, for my site to continue to use .net4 - and not the new 4.5? so that I can have the site operate under 4.0, and the API under 4.5? - Or is it possible to have the API (using the Entity Framework) run under .net 4.0 Thank you, Mark

Accepted Answer

You can use both web-api and entity framework without installing .net4.5.

You can add web-api to an existing project by installing the nuget package "Microsoft.AspNet.WebApi" (release candidate)
