Does SharePoint 2007 have assemblies for .NET 4 or newer?

I have a MVC4 web application on the same servers as my SharePoint 2007 farm.

I want to use search and lists from SharePoint, which seems like it has to use web services.

Very slow and no support for strongly typed data and LINQ queries.

Can (or when) can I use a .NET 4 or newer app to access SharePoint usnig binaries not web services?

Thanks.
