How to start ASP.net 4.0 app on server that has only ASP.net 2.0?

Is it possible? 开发者_运维技巧(without installing asp.net 4.0)

It is not possible without having ASP.net 4.0 on the server unless you rebuild your app for ASP.net 2.0.

---

It's not possible if there is no 4.0 framework installed. Ask your provider to change it to .net 4.0 if possible.

Not possible

You should install .net 4.0

app written in .net 2 will work on .net 4 but the reverse is not possible
