Which version of MVC am I using?

Open web.config file and find the System.Web.Mvc assembly definition:

assembly="System.Web.Mvc, Version=3.0.0.0 ..."

It's an MVC3 as you see. Via web you can use MvcDiagnostics which is similar to phpinfo() functionality in PHP.

Select the System.Web.Mvc assembly in the "References" folder in the solution explorer. Bring up the properties window (F4) and check the Version

Reference Properties

Another solution is to search for mvc in nuget (right click on your MVC project in visual studio and select "Manage Nuget Packages").

This will show you the version currently installed - enter image description here

And it'll also allow you to update the MVC version - enter image description here

typeof(Controller).Assembly.GetName().Version

Gives the current version programmatically.

I had this question because there is no MVC5 template in VS 2013. We had to select ASP.NET web application and then choose MVC from the next window.

You can check in the System.Web.Mvc dll's properties like in the below image.
