Can I use Visual Studio 2010 and not upgrade to .NET Framework 4.0?

Question

I have many Visual Studio 2008 web projects targeted at the .NET Framework 3.5. I want to start using Visual Studio 2010, but the .NET Framework 4.0 isn't very well supported by web hosting companies just yet. It seems to make sense to stick with the .NET Framework 3.5 for now. If I open my projects in Visual Studio 2010 and leave them targeted at the .NET Framework 3.5, am I going to have problems?

Answer 2

Answer 3
