MVC3 EF5 query plan caching

I have MVC3 project with target framework 4.0. I am developing under VS2010. I have .NET 4.5 installed of my machine. I use PostgreSQL as database server.

I read that EF4 and DbContext does not support compiled query and query plan caching.

So i just changed referenced library from EF4 to EF5, because this version caches query by default and i am still using MVC3 and VS2010.

In VS2010 i cannot set target framework 4.5 for my web project, but i set it in web.config file.

SO my question is:

How can i determine, if EF5 in my MVC3 really caches autocompiled LINQ queries? Is there any static class or tool, which contains these queries or?

Thanks. Regards
