Convert a web app created in VS 2010 ASP.NET 4.0 to ASP.NET 3.5

Question

I've made a web app in VS 2010 and by default, I think it uses the .NET Framework 4.0. Problem is, the server that's going to run it doesn't have 4.0.

Is there a way to downgrade the project? I'm not really knowledgeable with web hosting or web servers so I don't really know which is easier, downgrading the project or upgrading the web server. It's a company web server by the way, so I'm not sure about the legalities and stuff. It's free though, right?

Answer 1

Just right-click on the project in the Solution Explorer and go to properties. Under the "Application" tab, change the "Target Framework" from 4.0 to 3.5. That should do it provided you are not using any code features unique to 4.0.

If you can update the server easily, I would recommend that so that you have the 4.0 framework available to you going forward. The .NET framework is a free download.

Answer 2

Right-click on the project name and select Properties On the Application tab, you should see a Target framework: dropdown.
