Add 4.5 project inside a solution with 4.0 projects

Question

Can I add a 4.5 project inside a solution with only 4.0 projects?

Example:

-ProductSolution
   -Product.Domain.csproj (4.0)
   -Product.Web.csproj (4.0)
   -Product.WebApi.csproj (4.5)

I can't migrate my projects right now. And I want to add an Web Api and reference it to my Product.Domain project.

Thanks for any help.

You can't. A 4.0 project can't reference a 4.5 project so the end goal is unachievable.

It's the inverse man. A 4.5 project will reference a 4.0 proj. – wallybh Jan 29 '15 at 20:43
I would now delete this answer except for wallybh's comment. That makes two of us who got it backwards. – Joshua Jan 29 '15 at 21:15

You can have projects with multiple .Net versions in a single solution under Visual Studio,

BUT, you can't refer a .Net framework 4.5 version project inside an older version's project.

So your project Product.WebApi.csproj (4.5) is based on 4.5, you can't add reference to it in Product.Domain.csproj (4.0)
