Entity Framework: Version 6.1.3
Unity: Version 4.0.1
Unity.MVC: Version 4.0.1

This Example is using Hybrid Model for ORM. Here tabels, Stored procedures are created in database, then they are map with configuration mannually.

Stored Procedure Mapping Example:

public partial class DatabaseContext : IDatabaseContext
{
	public IEnumerable<CustomerOrderHistory> CustomerOrderHistory(string customerID)
	{
		var customerIDParameter = customerID != null ?
			new SqlParameter("@CustomerID", customerID) :
			new SqlParameter("@CustomerID", typeof (string));

		return Database.SqlQuery<CustomerOrderHistory>("CustOrderHist @CustomerID", customerIDParameter);
	}
}

Note: Here DatabaseContext class is a partial class. And CustOrderHist is name of stored procedure you want to pass.

Specifications basic:

public static class QuerySpecifications(){
	public virtual Expression<Func<TEntity, bool>> Query(int id)
	{
		return Expression<Func<TEntity, bool>>(a=>a.Id==id);
	}
}

Utility (Demo.Common.Utils):

1. CustomCrypto class:
	Provides methosd for encypting and decrypting text.
2. XmlSerializer class:
	Provides methods to serializa and deserialize object and xml string, also from file.

Extended classes (Demo.Common.ExtendedClass):

1. BaseController Class:
	Base controller class to inherit by controllers in MVC.
	Filter Attributes are added.
	Also extends controller class of System.Web.MVC.
2. CustomJsonResult Class:
	Extends ActionResult class.
	Used to return data in JSON format.

Fault Exception in WCF

1. Add  [FaultContract(typeof(ServiceException))] on contract
2. Add fault using below code
	
	throw new FaultException<ServiceException>(ExceptionManager.
                    HandleException("Product ID does not exist in system."));

	throw new FaultException<ServiceException>(ExceptionManager.
                    HandleException(ex));

Note: Exception manager itself log exception details. So no need to add logs in WCF methods.

Handling Session Authentication in Javascript side:

$(document).ajaxError(function (e, xhr) {
	if (xhr.status == 401)
		window.location = "/Account/Login";
	else if (xhr.status == 403)
		alert("You have no enough permissions to request this resource.");
});
