CSHTML rendering text only - static page?

This is a continuation of my previous question (.CSHTML pages will not render), but I am no longer getting a 500 error, thus the new post. My pages are now just rendering plain text / html (regardless of what I do).

I can get the pages to work correctly if I try to view them through WebMatrix3, but I cannot view them from the browser (either localhost or through the web).

I recently realized that my pages were set up for ASP.NET v2.0, which I am guessing does not support .cshtml. So, I changed everything to v4.0 but I still don't have any luck view the pages correctly. It's just plain text.

I have:

• MVC 3 installed
• IIS 7.5 on Win7 Home Premium
• The dir of the pages that I want to load converted to application
• web.config functioning, though I am not sure what else, if anything I need to have it in
• My server functioning normally with HTML, .css, .php, python, etc... But I am having horrible luck with any ASP.NET functionality (this includes .aspx).

I really don't know what other information I need to put here, but if you ask for it, I shall provide it.

EDIT 1:
Now I am just getting 404 errors on any .cshtml page I try to view. This happened before when I didn't have the MIME types in, but was corrected (to at least plain text) when I entered the MIME type in. I have no idea what is going on... at this point I am almost ready to just uninstall everything and try to start over. =\

EDIT 2:
Okay, so I have gotten rid of my 404 and 500 errors. I ended up adding a privileged user to the application pool (advanced settings > process model > Identity). It was set as defaultAppPool before. Now I am getting this:

Type 'ASP._Page_default2_cshtml' does not inherit from 'System.Web.WebPages.WebPage'.

Any more ideas? Oh, and creating a new application didn't help, but it was a good idea.

It could be that an older version of System.Web.WebPages.dll is loaded to memory, and it tries to cast the your cshtml page to a version of WebPages class from that dll.

To test this, try to see what http modules are currently registered:

var allModules = HttpContext.Current.ApplicationInstance.Modules;
for( int i = 0; i < allModules.Count; i++ ) {
    Trace(allModules.GetKey(i));
}

In my case that was:

....
__DynamicModule_System.Web.WebPages.WebPageHttpModule, System.Web.WebPages, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35_bca8e05a-5746-45b0-be95-2b920b455ccf

__DynamicModule_System.Web.WebPages.WebPageHttpModule, System.Web.WebPages, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35_c1a67b42-31a9-47f1-8483-9e712fabe2a7

To fix the problem you need to replace the older version of System.Web.WebPages.dll in your /Bin folders, or some other dlls that might be referencing it.
