Can ASP.NET MVC 3 run inside a ASP.NET 3.5 web site?

I would like to know if it is at all possible to get an MVC3 solution wrapped in a CWAB (Composite Web Application Block) solution built in 3.5?

I'm aware that in IIS, 2.0/3.5 and 4.0 sites can run next to each other (but in different application pools) but because of the CWAB layer I do not have this luxu开发者_高级运维ry. I got MVC2 running successfully before but MVC2 is on the 2.0 runtime if what I've read is true.

I would really like to use Razor as well so going back to MVC2 in this scenario is not really an option.

It should be possible. Just set your application pool runtime to 4.0 instead of 2.0.

.NET 4.0 runtime will be able to handle .NET 3.5 assemblies.

Razor requires features in .NET 4.0. However Tom Clarkson has a post called ASP.NET MVC 3 Razor View in SharePoint that talks about a (not-so-pretty) work-around. Basically, generate the view code from the cshtml files in .NET 4 and you can use them in .NET 3.5 (with a modified RazorEngine).

I'm encountering the same issue. The way I'm going to handle it is to write a WCF "front end" to SharePoint (.Net 3.5) and this will allow me to write the MVC app using MVC 3.
