Develop Reference

Protobuf-net object graph reference with surrogate

As far as I know, protobuf-net starting from v2 supports references but they cannot be used in conjunction with surrogate (exception "A reference-tracked object changed reference during deserialization" is thrown in this case)
I'm wondering if there is some workaround that I didn't consider to make it works.
Here following the code of my test case that reproduces the above exception.

I think for now this is just an unsupported scenario and I'm unaware of a way to make it magically work; it may be something that I can get back to at some point, but there are many much higher priority things that would take precedence.
My usual advice here - and this applies to any serializer, not just protobuf-net: any time you find yourself hitting a limitation of the serializer, or even just something that is awkward to configure in the serializer: stop fighting the serializer. This kind of problem almost always arises when people try to serialize their regular domain model, and something in the domain model isn't a perfect fit for their chosen serializer. Instead of trying arcane magic: split your model - have your domain model be a good fit for what you want your application to see, and create a separate model that is a great fit for your serializer. Then you don't need concepts like "surrogates". If you're using multiple serialization formats, or have multiple different "versions" of layout in the same serialization format: have multiple serialization models.
It really isn't worth the headache of trying to make on model serve multiple masters.

Since I understand that will be not a supported scenario, I found a way to handle this and I'd like to share my complete solution, in case someone else needs this (or if someone else wanted to share a better solution or improve my approach)

Get specific property from all items from the list

public class Contact

private string _firstName;
private string _lastName;
private int _age;
/// <summary>
/// Constructor
/// </summary>
/// <param name="fname">Contact's First Name</param>
/// <param name="lname">Contact's Last Name</param>

public Contact(string fname, string lname, int age)
{
_firstName = fname;
_lastName = lname;
_age = age;
}
/// <summary>

{

{
return _lastName;
}
set
{
_lastName = value;
}

{

}
set
{
_firstName = value;
}
}
/// <summary>
/// Contact Age
/// </summary>
public int Age
{
get
{
return _age;
}
set
{
_age = value;
}
}
}
and here I am creating my list:
private List<Contact> _contactList;
_contactList = new List<Contact>();
_contactList.Add(new Contact("John", "Jackson", 45));
_contactList.Add(new Contact("Jack", "Doe", 20));
_contactList.Add(new Contact("Jassy", "Dol", 19));
_contactList.Add(new Contact("Sam", "Josin", 44));
Right now I am trying to get all the first names of all the contacts in separate list using LINQ.
So far I tried:
public List<string> FirstNames
{
get
{
return _contactList.Where(C => C.FirstName.ToList());
}
}

You want to use the Select method, not Where here:
_contactList.Select(C => C.FirstName).ToList();
Further, the need for the ToList() only exists because the property demands it. You could return an IEnumerable<string> instead if you wanted to get rid of that.

public List<string> FirstNames
{
get
{
return _contactList.Select(C => C.FirstName).ToList();
}
}

AddObject is not working

In my .net (3.5) application with EF I use following code to insert new record, but AddObject() is not working.
I am surprise because it happens first time, even before when I had worked on EF at that time its was working.

e.SaveChanges();

And its give following error
Error 1 'System.Data.Objects.ObjectQuery' does not contain a definition for 'AddObject' and no extension method 'AddObject' accepting a first argument of type 'System.Data.Objects.ObjectQuery' could be found (are you missing a using directive or an assembly reference?)

.NET version 3.5 exposes ObjectQuery<T> versus ObjectSet<T> in .NET 4.0. Therefor you will need to use either e.AddTotbAirLines(tbAirLine) or e.AddObject("tbAirLines", tbAirLine). Both can be found on line 185 of the submitted generated code. In .NET 4.0 they decided to implement it like you were showing in your question.

NopCommerce / Entity Framework: Migration Error With Products Table

I currently have a very annoying issue with updating a NopCommerce database from Entity Framework.
BACKGROUND:
I am writing a small tool to migrate one type of outdated ecommerce app to nopCommerce.
THE ERROR:
The conversion of a datetime2 data type to a datetime data type resulted in an out-of-range value.
The statement has been terminated.
WHAT I HAVE DONE TO TRY RESOLVE IT
In the past, this sort of error came up when I had a DateTime property that was uninitialized (year 0001).. but in this case, that is not the issue. I looked and made sure all the DateTime properties were being set. As that didn't work, I also tried making the db column datetime2(7) but no luck. Finally I set it to NULLABLE but it still gave me the same error. So, there's obviously something else going on here and EF is throwing some unhelpful error. I had wondered if there was perhaps an insert trigger (or any trigger for that matter) on the table which was trying to perhaps create an entry in the product variant table or another table where the datetime error was then coming from, but that is not the case.
THE CODE:
foreach (var piloProduct in piloProducts)
{
var product = new Models.Nop.Product
{
Name = piloProduct.Name,
ShortDescription = piloProduct.ShortDescription,
FullDescription = piloProduct.FullDescription,
ProductTemplateId = 1,
ShowOnHomePage = false,
MetaKeywords = piloProduct.MetaKeywords,
MetaDescription = piloProduct.MetaDescription,
MetaTitle = piloProduct.MetaTitle,
SeName = piloProduct.SeName,
AllowCustomerReviews = false,
ApprovedRatingSum = 0,
NotApprovedRatingSum = 0,
ApprovedTotalReviews = 0,
NotApprovedTotalReviews = 0,
Published = true,
Deleted = false,
CreatedOnUtc = DateTime.UtcNow,
UpdatedOnUtc = DateTime.UtcNow
};
nopDb.Products.AddObject(product);
}
nopDb.SaveChanges();
I'm at a complete loss with this one, as the above code is really simple and straightforward. Any help much appreciated.
UPDATE
I have just tried using Linq-To-SQL classes instead of Entity Framework EDMX, but had the exact same problem. The strange thing is, I ran an "INSERT INTO" statment on the table directly from SQL Management Studio but it worked.. go figure... is there any way to see exactly what "INSERT" statements are being generated by either EF or Linq-To-SQL?
And here's the EDMX generated model requested by Mark Oreta:

Right, I figured out what was going on.. basically, I am running this all in a Transaction and I was exporting other entities (categories) before the products. The problem is that i did not call SaveChanges() after adding all the Categories... so the error that was coming up was with regards to the Categories table and not the Products table, but I only got the message when I called SaveChanges() which was after I added the Products as well.. very confusing.. I hope in future they will make it clearer by saying which table the error was coming from.. that would save a lot of time.
This is my situation and not you can see why I didn't immediately pick up what was wrong:
using (var transactionScope = new TransactionScope(TransactionScopeOption.Required, TimeSpan.FromMinutes(30)))
using (var piloDB = new PiloEntities())
using (var eSalesDB = new ESalesEntities())
{
ExportCategories(piloDB, eSalesDB); //SaveChanges() not called in here
ExportProducts(piloDB, eSalesDB); //SaveChanges() is called in here
//export other...
