Can I open old Visual Studio Solutions (2005,2008, 2010,2013) in Visual Studio 2015 without upgrading the projects?

Question

I read on Scott Hanselman's Blog , "I'm using Visual Studio 2015 to edit even .NET 2.0 apps so I'm not using older versions of VS," .

I also support old .Net solutions that open in previous versions of Visual Studio (2005, 2008, 2010, 2013). Is it possible with VS2015 to open these old solutions with out upgrading them?

I don't mind if they don't target the latest framework, it would just be handy to use a single version of Visual Studio rather than have 5 versions installed side by side.

You can use VS2015 to open or change apps that use older .NET framework (without having to upgrade to newer .NET framework).

Also, you can install VS2015 and run it side by side older VS.
