and I enter the . Metadata does not appear as an option....any suggestions

I am new at this.

I am using .NET Framework 3.5

Please use the following namespace if you are upgrading from EF5 to EF6 Replace System.Data.Metadata.Edm.RelationshipMultiplicity with System.Data.Entity.Core.Metadata.Edm.RelationshipMultiplicity, need not change anything else apart from above because it solves my problem

If you're using EF6, then you need to add a reference to System.Data.Entity.dll

After than you must include the namespace System.Data.Entity.Core

Basically, from EF6 all classes in System.Data have been moved to System.Data.Entity.Core.

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

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)

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