Lync Cracker - MVC 5 Demo
Database tables:
CREATE TABLE [dbo].[Student]([ID] [int] IDENTITY(1,1) NOT NULL,
[FirstName] [varchar](100) NULL,
[LastName] [varchar](100) NULL,
[StudentNumber] [varchar](100) NULL,
[IsActive] [bit] NOT NULL,
[CreatedBy] [varchar](100) NULL,
[DateCreated] [datetime2](7) NULL,
[UpdatedBy] [varchar](100) NULL,
[LastUpdated] [datetime2](7) NULL,
[Timestamp] [timestamp] NOT NULL
)
CREATE TABLE [dbo].[Subject](
[ID] [int] IDENTITY(1,1) NOT NULL,
[StudentID] [int] NULL,
[SubjectName] [varchar](500) NULL,
[Credits] [float] NULL,
[IsActive] [bit] NOT NULL,
[CreatedBy] [varchar](100) NULL,
[DateCreated] [datetime2](7) NULL,
[UpdatedBy] [varchar](100) NULL,
[LastUpdated] [datetime2](7) NULL,
[Timestamp] [timestamp] NOT NULL
)
Create that EDMX for the database & Create partial Classes for Data Annotation.
[MetadataType(typeof(StudentMetaData))]public partial class Student
{
}
public class StudentMetaData
{
[Display(Name = "Student_FirstName_Label", ResourceType = (typeof(Resources.Resources)))]
[Required(ErrorMessageResourceName = "Student_FirstName_Required", ErrorMessageResourceType = (typeof(Resources.Resources)))]
public string FirstName { get; set; }
}
Implement Provider Classes:
1. ProviderBase.cspublic class ProviderBase

public LyncCrackerTestEntities DB
{
get
{
if (_db == null)
{
_db=new LyncCrackerTestEntities();

2. StudentProvider.cs

Add Unity.MVC5
public static class UnityConfig
