in this article, I will show how to take a medium-small demo app written using Visual Studio 2013, ASP.NET 4.5, VC 5, and Entity Framework 6 and turn it into a working ASP.NET 5 app employing Visual Studio 2015, MVC 6 and Entity Framework 7. And the new app will happily run on either the .NET 4.6 CLR or the .NET Core CLR. Let's get started.
public static void PrintSum(int a, int b)
{
Console.WriteLine("Sum of a {0} b {1} is {2}", a, b, a + b);
} Console::WriteLine(string, object, object, object)
public static void PrintA(int a)
{
Console.WriteLine("a is " + a);
} 
public static void PrintA(int a)
{
Console.WriteLine("a is {0}", a.ToString());
} 
public static int Sum(IEnumerable<int> list)
{
var sum = 0;
foreach (var number in list)
{
sum += number;
}
return sum;

و میخواهید توسط outer join لیست تمامی پرسنل و محل تولد و محل صدور را (در صورت وجود) داشته باشید.
در sql گرفتن نتیجه ذکر شده بصورت زیر به راحتی قابل انجام است
SELECT
dbo.tbl_Personnel.ID,
dbo.tbl_Personnel.FirstName,
dbo.tbl_Personnel.LastName,
dbo.tbl_GeographyPosition.Title AS IssuanceLocation,
tbl_GeographyPosition_1.Title AS BirthLocation
FROM dbo.tbl_Personnel LEFT OUTER JOIN
dbo.tbl_GeographyPosition AS tbl_GeographyPosition_1 ON
dbo.tbl_Personnel.BirthLocationGeographyPositionID = tbl_GeographyPosition_1.ID LEFT OUTER JOIN
dbo.tbl_GeographyPosition ON dbo.tbl_Personnel.IssuanceLocationGeographyPositionID = dbo.tbl_GeographyPosition.ID اما در ef با توجه به خواص راهبری کمتر از join استفاده میکنیم در ضمن به هیچ وجه از Left Outer Join و Right Outer Join استفاده نمی‌شود و باید کوئری فوق را با کد زیر شبیه سازی کرد
var contex = new PersonnelEntities();
var Query = from Personnel in contex.tbl_Personnel
join IssuanceLocation in contex.tbl_GeographyPosition on
Personnel.IssuanceLocationGeographyPositionID equals IssuanceLocation.ID into AIssuanceLocation
from IL in AIssuanceLocation.DefaultIfEmpty()
join BirthLocation in contex.tbl_GeographyPosition on

}; This guest blog post is the first of a 3-part series written by Windows MVP Jani Nevalainen.
When I tell my fellow computer scientists or software developers that I'm interested in philosophy of science, they first look a bit confused, then we have a really interesting discussion about it and then they ask me for some interesting books they could read about it. Given that Christmas is just around the corner and some of the readers might still be looking for a good present to get, I thought that now is the perfect time to turn my answer into a blog post!
