VS 2010 : Ado.Net Entity Data Model Error

Recently encountered an error when trying to add an item on Ado.Net Entity Data Model in a Visual Studio 2010 project.

error01

The problem was I couldn't find the particular project item after i created the project. As usual in situations like this, I googled a few articles, all of which advise to re-install the particular tool or  to re-install Visual Studio. After several attempts at re-installing the tool, i finally found out the reason the particular item was not there.

error02


Silly me, but the application target framework was actually set to ".Net Framework 4 Client Profile" instead of the standard ".Net Framework 4". After changing the target framework, everything was fine.
