How do I tell what version of .net i am compiling with, and how would I change it?

I'm using VS2010 Premium. I am compiling and running an application locally. When i upload it a hosted server, I'm not seeing the results I am expecting. I think this might be cause my the host not having the same ver开发者_运维问答sion of .net I have. then are on .Net 2.

How can I tell what version of .Net I am compiling against? How can I change that version to another (in this case .Net 2)?

Thanks,

For each project, look in the project properties screen, Application Tab, there is a drop down labeled Target Framework...

You can also try Solution Properties from VSCommands 2010 extension. It allows you to edit Target Framework, Reference Paths and other settings for all projects from one place (instead of going to properties screen of each project separately):
