title: Using ASP.NET MVC 4 and Web API components within a .NET f/w 4.0 and VS2010-constructed app
body: <p>I'm a little confused about one thing with version levels of various .NET software components related to ASP.NET MVC and the web api.  Now I know VS2012 and .NET f/w 4.5 are going RTM "real soon now", but I don't want to make that up-transition for awhile (as in 6 months or longer).  I am coding a new app right now whose initial incarnation (dictated by consulting client) has to be .NET f/w 4.0 and utilizing VS2010 (yes I know you can target downwards with VS2012 but that is not an option for me in this case - as a consultant you are sometimes dictated the tools/versions etc that you MUST use for a contract).  So finally to the crux of my question - I just came across an article on MSDN by Mike Wasson, written in Jan/Feb 2012 timeframe, and it looks as if he used VS2010 and .NET f/w 4.0, but demonstrating the new-ish Web API technology utilizing ASP.NET MVC 4.  So it IS possible to install the ASP.NET MVC 4 component within the context of .NET f/w 4.0 and VS2010, AND utilize the Web API component?  Which, if that is true, I might want to do with this particular project rather than just using ASP.NET MVC 3 (and without using the Web API stuff at all), which is what i thought I would need to do.  It's just that I thought to use ASP.NET MVC 4 and/or the Web API stuff, one HAD to use .NET f/w 4.5 RC and VS2012 RC prior to Sep 12 (or their RTMs after Sep 12).  Is that not correct?</p>
