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.

1. 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?
2. Or is it possible to have the API (using the Entity Framework)
   run under .net 4.0

Thank you,

Mark

Answer 1

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)
