Entity fram work with WCF

Posted By:      Posted Date: October 17, 2010    Points: 0   Category :WCF

I have one visual studio 2010 solution which have four projects Data access layer(Entity framework), Business Logic, business entity and Service layer. I have write nice code for each layer including test and I have check whether it write and read data on database by calling business logic . but what I face is when I write service layer... I just include bussinses logic and bussiness entity using add reference then I call the function(metho) inside bussiness logic by just creating object of it. I have bulid the soultion, there is no error so I just run but it displlay some excetpion inside the data access layer that I donot face during when I call using console application. that is

"The specified named connection is either not found in the configuration, not intended to be used with the EntityClient provider, or not valid."

this exception is displayed inside the the .cs file inside edmx (entity framwork desinger).

please forward me some suggestion.

Server-side validation on an Entity Framework required field (property) does not work!

Has anyone had issues getting server-side validation on an Entity Framework required field (property) to work? The data type is a string (nvarchar). Server-side validation for required fields of other data types WORK fine. Only string fields have issues. I get the following error on UpdateModel(obj); of my POST method within the controller. Exception Details: System.Data.ConstraintException: This property cannot be set to a  null value.Source Error: Line 4500:                OnTextChanging(value);Line 4501:                ReportPropertyChanging("Text");Line 4502:                _Text = StructuralObject.SetValidValue(value, false);Line 4503:                ReportPropertyChanged("Text");Line 4504:                OnTextChanged(); I've even tried data annotations like this but it seems to get ignored.     [MetadataType(typeof(ObjMD))]     public partial class Obj     {

An Entity Relationship Diagram Example

An Entity Relationship Diagram conveys a lot of information with a very concise notation. The important part to keep in mind is to limit what you're reading using the following technique:

Choose two entities (e.g. Company and Employee)
Pick one that you're interested in (e.g. how a single Company relates to employees)
Read the notation on the second entity (e.g. the crow's feet with the O above it next to the Employee entity).

Multiple database support with Entity Framework

One of the features introduced in Entity Framework is being database independent. Which mean each database provider can support Entity Framework by implementing its provider.

This feature allows you build applications independent from the underplaying database provider. In this post I'm going to show how to build an application that support multiple databases using same conceptual model made by Entity Framework.

Creating a Generic Entity Framework 4.0 Repository

With .NET 4.0 right around the corner, I thought it would be cool to download Visual Studio 2010 beta 2 and start playing around with the next release of Entity Framework.

The initial release of Entity Framework came with a great deal of criticism. To make matters worse, there was a large uproar when it was rumored that Microsoft would be abandoning LINQ to SQL, in favor of Entity Framework. This was because, at the time, many developers felt Entity Framework was an inferior technology to LINQ to SQL. To set things right, Microsoft proactively moved forward with improving Entity Framework, in time for the 4.0 release of the .NET Framework. This is good news because my initial impressions, so far, have been nothing but positive.

Entity Framework 4 Tips for WinForms Development

I've been recently working on a smart client (WinForms) application backed by Entitiy Framework 4 (EF4) on Visual Studio 2010. In this blog post I will try to give you some tips regarding some limitations and points to be careful about EF4.

Looking for guidance: wanting to work with AJAX architecture



I'm starting a small website that will be backed by a database, and will allow a small number of users to authenticate and select an entry in the database, and then view (and optionally update) a corresponding entry (think master-detail).

I have some flexibility in how I'll do this, but I'd really like to incorperate some newer AJAX style coding, eliminating some page postbacks. I think this is a great opportunity to learn the concepts well.

I'll probably go with an ASP.NET 4.0 site. From what I've seen there are MANY ways to go about this:

-WCF Data Services to expose the data, and consume in ASP.NET

-Page methods to expose the data, separate method to update the data

-I'd rather avoid the UpdatePanel because I'm really looking for a full hands-on approach, with learning client side scripting being an objective as well.

Beyond that, it seems that one can use jQuery to build clientside templates, but also one can use the ASP.NET AJAX template engine (in ASP.NET 4.0 I believe).

A concern I have: users should only be able to work with the data exposed via these endpoints if they are logged into the website. Hopefully I can somehow reuse the ASP.NET forms authentication cookie for this purpose. 

Well, I hope I've posted enough to a

animate effect work but the render items are messed up.


Hi all,

     I have a very unique problem, humm i think. I am using a jquery effect that animate bounce effect, i have a line in my javascript pageLoad function $("#UserBrowserInfoDIV").show('bounce'); - the effects run smoothly but what it does is mess up the bolded text in the div. I have try the items inside the div without bolding and it works fine and no render problem but when bolded the text that are bolded is quite messed up, and barely readable.

Please let me know is there anything else i can do i really would like use this effect.

P.S all the effect have the same render problem, and i am using ie8 under compatibility mode.

Can I replace the EntityObject as base-class in Entity Designer 3.5 sp1?


I'm using EF3.5sp1 for a project, and I've been working around many of its problems... as such, my entity partial classes have a lot of logic in them for change-tracking and whatnot.  Obviously, I'd like to factor this logic out into a common base class, but of course all my objects must derive from EntityObject.  Is it possible to tell them to derive from some class of my own invention (which would actually likely derive from EntityObject themselves)?

I'd rather avoid editing the EDMX file unless the changes will be safe on entity-model-update, since I'm still making changes to the database schema in this early state of my project.


Also, is there any good workaround for the fact that the change isn't tracked when you change EntityReference.EntityKey?

Data accessors or Entity framework


The entlib 5 sugest me to use with data accessors for mapping data from database to my data objects (ORM).

But in .NET 3.5 and especially in .NET 4, I can use in entity framework as ORM methodology for data objects.

What data accessors uses advantages over the entity framework?

What differences that should be affect on my using decisions?

Category attribute of user control property does not work correctly in categories tab.



I have a User Control (ascx) and a property which a want to display in my categories tab in Visual Studio in the category named "Styles".

[Category("Styles"), DefaultValue(""), Description("The value for formating something.")]
public String MyFormatProperty
set { /* the code for set */; }
get { /* the code for get */; }

And here is the problem: Actually I do not need a get, because I only have to set the property (write only property). But when I omit the get, the property is displayed in the "Misc" category in the categories tab in Visual Studio. Only when I code the get as well, then the property is displayed correctly in the "Styles" category in the categories tab in Visual Studio.

Does anybody know why? How can I display the category correctly only with set?

Thanks, S.
