What version of .net will MVC 2 require?

Will MVC 2 run on .net framework versio开发者_运维知识库n 4.0 or 3.5 sp1? Has Microsoft even made an announcement yet as to what the requirements are?

Also, Will MVC 2 be an installation separate from .net 4.0 or will it be installed with 4.0?

Per Scott Guthrie, ASP.NET MVC 2 is designed to work with both VS 2008 / .NET 3.5, as well as with VS 2010 / .NET 4.

for the mvc 2 installation question

ASP.NET MVC 2 is a built-in component of VS 2010 / .NET 4 – which means you will not have to download or install anything to get it once you install any version of Visual Studio 2010. The current public VS 2010 Beta 2 release includes the ASP.NET MVC 2 Preview 2 release. The upcoming VS 2010 Release Candidate that will be available for download next month will have a more recent ASP.NET MVC 2 RC built-in.

It will run on .NET 3.5 SP1 and higher

MVC 2 will be fine with either. The next version of MVC will require 4.0 or later, but this new "2" is fine either way.

The final Visual Studio 2010 will have MVC 2 included. For now the MVC 2 release candidate is a download, available here.
