Cascade Delete and 1-to-1 (or 1-to-0..1) Relationships Here’s another episode in my ongoing mission to help folks be successful using the Entity Framework, as well as to learn more about how folks use the Entity Framework so that each release will be better than the last.  Today’s task: Using cascade delete with 1-to-1 relationships.The problem I got an email from a customer asking for help with getting cascade delete to work properly in his application.  After going through the normal obvious potenti...

Defining Constraints in an EF4 model that don’t exist in the database : Don't Be Iffy

In the first version of Entity Framework, if you wanted to create a PK/FK association between entities where there was no such constraint defined in the database you have to manually edit the SSDL (and lose that edit if you update the model from db). Why would you want to do this? The typical use case is when you are stuck with a database that is poorly designed and you are not allowed to make changes to it. In Entity Framework 4, as long as the Primary Keys are defined in the db (otherwise the entitie... (more)

When developing software that works with time stamped information, it is common to show the date and time at which an item was created or last updated. A user-friendly alternative is to display a relative time, such as "Two Hours Ago". (more)

Innovation Showcase : Confused about Windows Azure Billing?
published 1196 days, 5 hours, 18 minutes ago posted by wzackwzack 1196 days, 21 hours, 21 minutes ago
Monday, February 15, 2010 1:08:43 PM GMT Sunday, February 14, 2010 9:05:16 PM GMT
Confused about Windows Azure Billing? The Windows Azure Platform is based on an Operational Expenditure (OPEX) model as opposed to the on-premise Capital Expenditure (CAPEX) model that most of us are used to. This means that means that, while you pay nothing up front for using Azure storage and computational resources, you do have to understand how your use of those resources will be billed to you. This blog post does a pretty good job of explaining how this works. If you want to expl... (more)

Monitoring Applications in Windows Azure Hedgehog’s Cloud Application Monitor was created to fill a gap in creating application for the Azure Cloud. There is no easy way to monitor applications running in the cloud, and no quickly accessible repository of historical data. The Cloud Application Monitor downloads diagnostic information from the cloud and stores it in a local SQL server database. Hedgehog has posted this application on Codeplex as a free download. (more)

How to use Validation Controls in ASP.NET
published 1195 days, 7 hours, 8 minutes ago posted by KhaledKhaled 1197 days, 9 hours, 19 minutes ago

Using Validation Controls is faster than doing validation on the server side. Please note that there are some cases where you can’t set a rule. In that Case you will add those types of validation to your Business Logic Layer, when you validate in your Class Library before sending the Data to the Data Layer to be executed. There is only one reason why Microsoft created Validation controls. The Reason is simple “Never Trust the user input” (more)

When using model binding in an ASP.NET MVC application we make sure that our user interface elements matches with the domain object. But sometimes this is not possible as user interface contains elements which does not make any sense on the domain objects. In this article we will demonstrate how to implement ViewModels which closely reflects the elements on the interface (more)

When you first create a .NET 4.0 project inside VS 2010 and add reference to a .NET 3.5 DLL (say log4net or Rhino.Mocks), the project tends to not build. You can get errors as shown below. It might appear to be a CLR version issue – unable to run 2.0 DLL inside a 4.0 App Domain. And i thought that is what it was until now. You can get over this :) By default, VS 2010 creates the projects with Target Framework on the properties set to “.NET Framework 4 Client Profile”. You would have to change that... (more)

In this episode, guest Mark Pollack joins Peter to discuss the Spring.NET application framework. In a world driven by POJOs and POCOs, Mark tells us about how he originally created Spring.NET for a team of Java developers to enable a similar development experience in .NET. Since then, the framework has grown from a simple IoC container to a more powerful framework capable of separating cross-cutting concerns from business application logic. Also, Dmitry and Peter discuss Snoop, FastCGI 1.5, Windows Mob... (more)

Compiling this information was an interesting challenge. I could have simply copy-pasted from MSDN, but that would have been extremely tedious.
