Check what version of T4MVC is available:

Trying to update:

PM> Get-Package -Updates
No package updates are available from the current package source.   

What's broken in my installation?

Update:

• I use VS Express 2012 for Web Update 2 and NuGet 2.2.40116.9051
• The package updates are not shown in NuGet GUI too.

Answer 1

It seems to be a bug in NuGet, here is a bug report from somebody else: http://nuget.codeplex.com/workitem/3289

The workaround is simple: updates are working for individual projects, not for the solution.

Answer 2

When I tried on a test solution, I actually saw the same thing as you. But after cleaning my solution and restarting VS, it started working correctly.

So I'm not sure what the deal is, and it probably is a NuGet bug, but at least that might provide a workaround.
