Can I use views in folders linked from other projects? - asp.net-mvc

Question

I have several MVC projects in one solution.
Following this accepted answer: "Add as Link" for folders in Visual Studio projects, I am attempting to reuse .cshtml views across these proejcts by placing reusable views in a base project. So far, I have set up location formats in the "consuming" projects for the view-engine like this:
var locationFormats = new string[]
{
"~/Views/{1}/{0}.cshtml",
"~/Views/Shared/{0}.cshtml",
"~/Views/Common/{1}/{0}.cshtml",
"~/Views/Common/Shared/{0}.cshtml"
};
I have set up a recursive, linked directory in consuming projects' .csproj files to include common views like this:
<ItemGroup>
<Content Include="..\..\..\common.cms\CommonViews\**\*.*">
<Link>\Views\Common\%(RecursiveDir)%(FileName)%(Extension)</Link>
<CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
</Content>
</ItemGroup>
...and all the views are appearing in the consuming projects with the linked-file/cshtml(#) icon, so the paths are correct. For example, the following file is very clearly present in my test consuming project:
\Views\Common\Home\Index.cshtml
But when I run the project, I'm getting:
The view 'Index' or its master was not found or no view engine supports the searched locations. The following locations were searched:
~/Views/Home/Index.cshtml
~/Views/Shared/Index.cshtml
~/Views/Common/Home/Index.cshtml
~/Views/Common/Shared/Index.cshtml
Question
So I am wondering: is it even possible to link views in this way? What is missing, or what could be inhibiting this from working?
More generally, what about any non-compiled files I'd like to share? Is this technique never going to work?

I've found that this as a known bug in visual studio: Linked files in Web Application projects are not deployed properly. This goes back to VS-2008 but still affects VS-2010 and 2012 (not sure about 2013).
A workaround is detailed in this blog-post:
Using Linked Files with Web Application Projects.
If you just want the fix wihtout the explanation, you just need to paste the code below at the end of the .csproj file for your project (just before the closeing </project> tag). This will fix the problem for any linked, un-compiled files:
<!--
============================================================
_CopyWebApplication
MODIFIED: Ignores linked files as part of normal deployment logic.
This target will copy the build outputs along with the
content files into a _PublishedWebsites folder.
This Task is only necessary when $(OutDir) has been redirected
to a folder other than ~\bin such as is the case with Team Build.
