Exhibit: Server generated keys are only supported for identity columns
There is MS Visual Studio 2010 and MS .NET Framework 4 application PassGuideApp.
To access employee data from PassGuideDB ADO.NET Entity Framework is used to model
entities.
PassGuideApp includes an Employees entity.
The Employees entity include a EmployeeKey, a primary key field, with type Guid.
However, there is a problem when PassGuideApp uses the Save Changes method to save a
new instance of Employee entity.
How can you remedy the problem?
