Don't see Entity Framework Template after Visu

问题:

I just install Visual Studio 2010 on a 64 bit VM with Windows 7 64 bit. The VM is on an ESXi Hypervisor. When I tried to create my first project I don't see the Entity Framework template (ADO .NET Entity Framework). Am I missing a step here? Any and all help is appreciated.

@Will thanks for all the help. I was able to solve this problem by using the following steps:

1. Reinstall Visual Studio 2010 Professional a. Select Add New Components b. Click until you get to the comnponents selection screen c. de-select and re-select Visual Basic .NET and C#
   d. Click Update
2. Log back into Visual Studio 2010 Professional and you will have access to the ADO .NET Entity Framework

Thanks to all!!

I just had the very same problem. Actually, you have to check "SQL Server 2008 express" in Visual Studio installation, or Entity Framework won't be installed.

Make sure you're targeting 4.0 and not 3.5.

Unless I misunderstood your question, you have to start a project (web application, wpf application etc), and then add ado.net entity data model.
