If you open the references folder and locate system.data.entity, click the item, then check the runtime version number in the Properties explorer, you will see the sub version as well. Mine for instance shows v4.0.30319 with the Version property showing 4.0.0.0.

Another way to get the EF version you are using is to open the Package Manager Console (PMC) in Visual Studio and type Get-Package at the prompt. The first line with be for EntityFramework and list the version the project has installed.
<pre><code>PM> Get-Package

Id Version Description/Release Notes 
-- ------- ------------------------- 
EntityFramework 5.0.0 Entity Framework is Microsoft's recommended data access technology for new applications. 
jQuery 1.7.1.1 jQuery is a new kind of JavaScript Library.... </code></pre>
It displays much more and you may have to scroll back up to find the EF line, but this is the easiest way I know of to find out.

blocks|key|970107|text|可以在packages.config文件中查看它。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|970108|<?xml+version="1.0"+encoding="utf-8"?>

can check it in packages.config file.

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;packages&gt;
&lt;package id="EntityFramework" version="6.0.2" targetFramework="net40-Client" /&gt;

I believe there are two versions 1 and 2? And version 2 is referred to as Entity Framework 4.0?

How can I tell what version is being used in an application? 

This is in my web.config does this mean I am using version 2?

<pre><code>&lt;add assembly="System.Data.Entity, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" /&gt;

Determine version of Entity Framework I am using?
