Answer 1

if you use EF6, you should using System.Data.Entity.Core.Metadata.Edm.

Answer 2

You need to add the reference System.Data.Entity.dll.

You can also check which assembly is need to some class in msdn

For example, for the EntityType:

http://msdn.microsoft.com/en-us/library/system.data.metadata.edm.entitytype.aspx

And you will see there the information about the assembly:

Assembly: System.Data.Entity (in System.Data.Entity.dll)

Answer 3

Make sure you have referenced System.Data.Entity.dll in your project.
