Does ASP.NET MVC 3 Preview 1 (or the eventual RTM) supports .NET 3.5

Question

I've been looking for information regarding if the third version of ASP.NET MVC will support .NET 3.5 or not.

I haven't been able to find anything that either confirms it or denies it.

Answer 1

No.

Some parts of ASP.NET MVC 3 Preview are heavily tied to .NET 4.

System Requirements Supported Operating Systems:Windows 7;Windows Server 2003;Windows Server 2008;Windows Vista

.NET 4, ASP.NET 4, Visual Studio 2010 or Visual Web Developer 2010 are required to use certain parts of this feature.

For further reference: Comment by Scott Guthrie Microsoft VP .NET Framework
(direct link to the comment doesn't seem to work)

The changes all look great, Scott. But do you need Visual Studio 2010 for MVC3 or will it work in 2008?

ASP.NET MVC 3 takes a dependency on .NET 4 (for a lot of the features I listed above), so you do need VS 2010 since that is the only version of VS that works with .NET 4. You can though use Visual Web Developer 2010 Express (which is free) if you don't have VS 2010 installed.

Hope this helps,

Scott

Answer 2

In Scott Hanselman's interview with Phil Haack, Phil Haack stated that ASP.NET MVC 3 would be .NET 4.0 only.

From the transcript:

Scott Hanselman: So does this mean that there's no using MVC 3.0 outside of .NET 4.0?

Phil Haack: Correct.

Scott Hanselman: Okay. So 2.0 people can keep doing their thing but MVC 3.0 is a more than just a gentle nudge in the direction of moving towards .NET 4.0.

Phil Haack: Correct and Visual Studio 2010. So you won't be able to build MVC 3.0 apps using Visual Studio 2008.
